Two mobile apps being built with a visual editor

TL;DR: Choose a mobile app builder by weighing native store publishing against cheaper but limited PWAs, core features, editability, and total cost. Budget for Apple’s $99 yearly fee, Google’s $25 one-time fee, and usage-based scaling charges.

The mobile app builder you pick decides whether you can publish to the App Store and Google Play Store, what you’ll pay as your user base grows, and how much of the app you can change yourself once customers start asking for things. Native apps cost more to build and publish. Progressive web apps cost less, but they don’t have all the device features you might need.

The tool you choose matters, too. AI coding tools get a first version up fast, but the logic and data live in code. As the app grows, it can drift from what you imagined and get harder to change without a developer.

Template-based visual builders don’t leave you with code to maintain, but they can hold you back when your idea doesn’t fit their patterns. You could also hire a team to build a native app from scratch, which often costs tens of thousands of dollars (or more).

Below, you’ll learn the difference between native apps and PWAs and the core features every app needs. You’ll compare seven builders on pricing, publishing, hidden scaling costs, and how much of each app you can change yourself. Then you’ll estimate your total cost, including Apple and Google fees, and see how testing, store review, and updates work after you build.

What is a mobile app builder?

A mobile app builder is a platform that lets you build and publish a mobile app without writing the code yourself or hiring a developer. Depending on the builder, you end up with a true native app in the App Store and Google Play Store, a progressive web app (PWA) that runs in the browser, or a mobile-optimized website. You build by prompting an AI, editing in a visual editor, or both, and the right builder depends on the kind of app you need, what it costs as you grow, and how much of it you can change yourself.

AI coding tools, often called vibe coding tools, turn your prompt into code, and you’ll need programming skills to edit that code directly. Visual app builders usually keep the code out of your way, and you work in a drag-and-drop visual editor instead. Some of those no-code tools also use AI and let you work with prompts as well.

What to consider before you pick a mobile app builder

Before choosing a mobile app builder, consider eight factors: distribution type, core features, total cost, publishing workflow, timeline, scalability, security, and editability. The lowest sticker price rarely delivers the lowest total cost, so comparing platforms accurately means looking beyond the subscription fee.

Distribution type and core features

The format you choose shapes your publishing path and what the app can do. There are two options:

  • Progressive web apps (PWAs): Mobile-optimized websites that run in browsers and can be saved to home screens. They skip app store approval, but they can’t match everything a native app supports, and device access varies by browser and operating system.
  • Native iOS and Android apps: Published directly to the App Store and Google Play Store. They let your app tap into device capabilities like push notifications, camera, GPS, and store-based monetization.

Every app needs a baseline set of features. Here’s what to check for before you end up paying extra for the basics:

  • User authentication: People need to create accounts and log in securely. Almost every app needs this, and if a platform doesn’t offer it, you’ll end up patching together a third-party workaround.
  • Database functionality: Your app needs somewhere to store and retrieve user data across sessions, or it won’t remember users, save preferences, or hold onto any state between visits.
  • Push notifications: These bring users back when they have drifted away from your app. Native apps handle them directly through Apple and Google’s notification systems. PWAs usually need a workaround, and some platforms don’t support them at all.
  • Payment processing: This is how you make money from your app. Some platforms build in Apple and Google in-app purchases, while others rely on web payment tools like Stripe, so check which purchase types (subscriptions, one-time purchases, or both) a platform supports.
  • Offline capabilities: Your app should keep working even without a connection. That matters a lot for field workers, travelers, or anyone using your app somewhere signal is unreliable.

Cost, publishing, scalability, and editability

These six factors decide what you’ll pay and how well the app holds up after launch:

  • Total cost: Your monthly bill rarely stops at the subscription fee. Data storage limits, API call caps, AI credit or token allowances, collaborator seats, template purchases, and app store build fees can all add up fast.
  • Publishing workflow: With direct publishing, the platform packages and submits your app to Apple and Google for you. Manual export means downloading code, setting up Xcode or Android Studio, and submitting it yourself, which is a much bigger technical lift.
  • Timeline: It depends on the platform and how complex your app is. Prompt-based tools can get something working in minutes, though native apps still need app store review time. Template-based builders can launch in days if your app fits their patterns, while building from scratch usually takes longest.
  • Scalability: Check for auto-scaling infrastructure and clear usage limits. They show how the platform holds up as your user base grows past early testing.
  • Security: Look for version control so you can roll back a change that breaks something, plus privacy and security checks you can see and adjust yourself. If you’ll handle customer data, check for compliance standards like SOC 2 Type II.
  • Editability: Check whether you can change the app’s logic and data yourself, or only the screens. If changes to how the app works only happen through prompts or code, every fix depends on the AI or a developer.

Bubble: Best for web and native mobile apps from one fully visual editor

Bubble is a fully visual app builder for web apps, and Bubble for native mobile apps brings the same editor to iOS and Android. Building on Bubble starts with a conversation with the Bubble AI Agent. Describe your idea, and the Agent opens with a planning session, asking clarifying questions before it generates your design, database, and workflows, with privacy rules for each kind of data your app stores.

With native mobile app generation (beta), the Agent builds and edits iOS and Android apps end to end. It can also connect your app to third-party services by setting up API calls and installing plugins. You can publish to the web, the App Store, and the Google Play Store.

You can chat with the Agent to get a first version, or work in the visual editor yourself on design, database structure, privacy rules, or business logic. The Agent asks when a request could mean more than one thing, shows what it’s about to do, and summarizes what changed. Everything it builds shows up as visual elements and workflows you can read and edit yourself, with no code to hand off to a developer.

If you already work in Claude, ChatGPT, or Codex, you can build your Bubble app from there through the Bubble MCP (beta). With universal import, you can bring an app built with an AI coding tool into Bubble as a fully visual app. The beginner’s guide to AI and Bubble is a good place to start.

Bubble packages your app for the app stores, and you don’t need Xcode or Android Studio. You’ll still go through store setup, testing, and review before your app goes live.

Web and native mobile share one editor, one database, and one backend, so your web and mobile apps live in a single project. Hospitality operations platform SuiteOp built its native app on Bubble in two months, compared with an estimated 6–8 months, on the same backend and database as its web app. Co-founder Jean-Emmanuel Losi says, “Being able to use the same backend workflows, the same database — those things were really big time savers.”

Built-in hosting, a security dashboard on paid plans, and auto-scaling support your app as it grows. Bubble is SOC 2 Type II compliant and includes version control with rollback, so you can undo a change that breaks something.

Best for:

  • Founders who want to know how their app works: Workflows read as plain-language steps, like “When someone signs up, do this,” and the Agent explains what it built. When something behaves unexpectedly, you can see why and fix it without a technical co-founder.
  • Builders who want the app to work the way they imagined: You can generate a workflow with the Agent, then open it in the editor to inspect and adjust each step. It’s how you keep the app from drifting as you add features.
  • Projects that need custom business logic or specific design beyond templates: Bubble’s visual editor supports conditional logic, dynamic data, and pixel-level design control. Your app doesn’t have to look like everyone else’s.
  • Teams that want web and native mobile from one platform: A single project can power your marketing site, web app, and iOS and Android apps from the same backend. Traffic growth and new features don’t force a rebuild on another tool.

Limitations:

You’ll invest some time learning to read visual logic in Bubble’s editor. The Agent explains what it builds in plain language, and as you learn, you can see how your app works and make changes yourself. That understanding pays off when a customer asks for a new feature or you need to fix something without handing it to a developer.

Native mobile apps on Bubble support camera and photo library access, location services, and push notifications. In-app purchases (beta) currently cover subscriptions only, so one-time purchases like credits or tokens aren’t supported yet.

Pricing:

Bubble pricing is based on monthly workload units, which measure the server work your app does, instead of user counts. Rates differ depending on whether you publish web only, mobile only, or web and mobile, and every plan includes a monthly AI credit allowance.

  • Free plan: Getting started is free, with no time limit on building. Free plan apps can’t go live, and Bubble’s pricing page lists current workload allocations and any credit-card requirements.
  • Starter plan: Starter Web is $32/month billed annually or $39/month billed monthly. Starter Mobile is $42/month billed annually or $49/month billed monthly, and Starter Web & Mobile starts at $59/month billed annually. Includes app publishing with a custom domain.
  • Growth plan: From $119/month (web only), $169/month (mobile only), or $209/month (web and mobile), billed annually. Higher workload capacity for growing apps.
  • Team plan: From $349/month (web only), $449/month (mobile only), or $549/month (web and mobile), billed annually, for larger organizations.
  • Enterprise plan: Custom pricing for dedicated infrastructure and support.

Native iOS and Android publishing needs a paid Mobile or Web & Mobile plan, and higher tiers add more capacity, builds, and live-version limits. You can monitor workload usage, manage overages, and buy more workload when you need it.

You never depend on AI credits to build your app. Generating an app with the Agent doesn’t use them, and neither does editing in the visual editor. If you run out, nothing is charged automatically, the editor keeps working, and paid plans can buy more anytime.

Replit: Best for AI-first development with code access

Replit is an AI development platform where Agent writes your app in code, including the frontend, backend, and database. You build by chatting with Agent, and you can open any file in the workspace to read or edit what it wrote.

Deployment and hosting come built in, and Agent can set up a PostgreSQL database, authentication, and API connections, which you can also change in the code.

Replit also builds native mobile apps through Agent, as React Native apps with Expo. You can preview them in a browser-based iOS simulator or Android emulator, or on your phone in Expo Go. Replit guides you through preparing builds for TestFlight and App Store submission, but it doesn’t publish to Google Play yet.

Best for:

  • Builders who want AI to handle the full stack in code. Agent plans and builds the frontend, backend, and database, with deployment and hosting built in.
  • Builders who want to learn from what the AI writes. You can follow Agent’s work file by file and step in on a specific change when you’re ready.
  • Projects that need specific languages, packages, or libraries. Replit supports languages like Python alongside JavaScript and TypeScript, so a stack that depends on a particular library is within reach.
  • iOS apps with a guided path to the App Store. Replit prepares builds for TestFlight and App Store submission without setting up Xcode locally.

Limitations:

Replit doesn’t publish to Google Play yet, so an Android release means taking the code outside Replit to build and submit it yourself. Because the app’s logic and data live in code, changing how it works means prompting Agent again or editing the code directly. You can start without writing code, but debugging and precise changes go much faster if you can read TypeScript, Python, or JavaScript.

Pricing:

The free Starter tier covers basic projects with limited Agent access. Replit Core is $20/month, or $18/month billed annually, and includes full Agent with Plan and Build modes, one parallel Agent task, up to five collaborators, unlimited published apps, and a seven-day database restore window.

Replit Pro is $100/month, or $90/month billed annually, for up to 15 builders. It adds pooled, tiered credits, access to more capable Agent models, up to 10 parallel Agent tasks, credit rollover, and priority support. An Enterprise plan adds SOC 2 compliance, SSO/SAML, single-tenant environments, and dedicated support.

Bolt: Best for fast AI prototypes in code

Bolt, a product of StackBlitz, builds apps from a conversation with AI. It writes your app in JavaScript and shows a live preview beside the chat. You can make visual edits to properties like text, colors, and font size, or open the code and change it directly. Hosting and Bolt Database are built in for web apps.

For mobile, Bolt builds React Native apps with Expo. Ask for a mobile app in your first prompt, since web projects don’t switch to mobile easily. You can test on your phone by scanning a QR code from Bolt’s preview into the Expo Go app. Publishing happens outside Bolt: You download the code, install Expo’s command-line tools, and build and submit to the App Store and Google Play Store with an Expo account and your own Apple and Google developer accounts.

Best for:

  • Builders comfortable with code who want AI to write a JavaScript app. You get full access to the code, and you can download it or sync it to GitHub.
  • Rapid prototypes and demos. Bolt’s first drafts are visually polished, with detailed sample data, which helps when you need to validate an idea quickly.
  • Projects you plan to host elsewhere or hand to a developer. Because the app lives in code, you can move it anywhere.
  • Teams that already publish with Expo. If you know your way around EAS builds, App Store Connect, and Google Play Console, Bolt’s output fits that workflow.

Limitations:

Native builds, app store submission, and in-app purchases all happen outside Bolt, so plan time for Expo’s tools and a third-party service like RevenueCat for subscriptions. Beyond visual edits to properties like text and colors, changes to logic and data go through prompts, which use tokens, or through the code. If you don’t read JavaScript, a fully visual platform lets you see and change more of the app yourself.

Pricing:

As of October 29, 2026, the Free plan includes 1 million tokens a month with a 300,000-token daily cap, website hosting, and Bolt branding on published sites. Pro is $25/month billed monthly, with 10 million tokens a month that roll over, a custom domain, and no Bolt branding. Teams is $30 per member per month billed monthly and adds centralized billing, admin controls, and SSO. Enterprise pricing is custom. Expo’s build service has its own free and paid tiers, and Apple’s and Google’s developer fees are separate.

Thunkable: Best for simple native publishing

Thunkable builds native iOS and Android apps through drag-and-drop blocks and AI-assisted building, with publishing built in. Pre-built UI components and templates speed up initial builds, and direct integration with Apple and Google publishing tools removes technical barriers.

The visual block-based programming feels familiar to anyone who has used Scratch or similar educational coding tools. Thunkable supports data sources, cloud database features, Firebase-based user authentication, and Web API integrations, though you’ll need to configure Firebase yourself for authentication. You can test apps on real devices through the Thunkable Live mobile app before submitting to stores.

Best for:

  • Native apps where template-based UI patterns and basic CRUD operations meet your needs. A local business directory or event schedule app fits well here.
  • First-time app creators who want a fast path to app store approval. Direct publishing skips the manual export and configuration some alternatives require.
  • Individual builders or very small teams who don’t need real-time collaboration features or version control. Solo makers avoid Thunkable’s collaboration limits entirely.
  • Projects with straightforward, linear user flows that fit within Thunkable’s block-based logic system. Think tip calculators or simple habit trackers.

Limitations:

Thunkable covers most common app patterns, but check its capabilities first if your UI or architecture needs are unusual. The same goes for data-heavy apps: Confirm query, sync, and performance limits before building something data-intensive.

Plans cap AI tokens and screens, and publishing needs your own Google and Apple developer accounts. Let your subscription lapse and published apps may stop working, so check Thunkable’s terms before relying on this for a live product.

Pricing:

As of September 2026, the free tier includes 2,000 AI tokens, three public projects, and five screens per project. The Accelerator plan at $19/month (billed monthly) includes 20,000 AI tokens, five public projects, one private project, and 10 screens per project.

The Builder plan at $37/month (billed yearly) or $59/month (billed monthly) includes unlimited public projects, 10 private projects, unlimited screens, one live published app, 50,000 AI tokens, custom branding, and chat support. The Advanced plan at $99/month (billed yearly) or $189/month (billed monthly) includes 100,000 AI tokens and unlimited live published apps. Enterprise and Education plans are available with custom terms.

Glide: Best for spreadsheet-based PWAs

Glide turns spreadsheets into mobile-optimized progressive web apps. Connect a Google Sheets or Airtable base, apply a template, and Glide generates a functional PWA with data-driven UI automatically.

Hosting and updates run through the platform, and spreadsheet changes sync to your Glide app automatically, though it can take a few seconds or minutes depending on the data source. Pre-built components like lists, forms, calendars, and maps let you build interfaces without custom design work. Glide is SOC 2 Type II compliant and encrypts sensitive information in transit.

Best for:

  • Internal business tools, team directories, or operational dashboards built from existing spreadsheets. A field-service team can turn a Google Sheet of job sites into a searchable mobile view in an afternoon.
  • Projects where you already maintain data in Airtable or Google Sheets. Glide layers a mobile UI on top without asking you to migrate your data model.
  • Apps that don’t require app store distribution or deep device feature integration. Home-screen installation on a phone is often enough for internal or B2B tools.
  • Quick internal prototypes or concept-validation apps. Glide is useful when speed matters more than long-term customization, scale, or native app store distribution.

Limitations:

Because Glide builds PWAs, native-device capabilities are limited. Glide deprecated its Push Notification feature in December 2024 due to inconsistent PWA support across devices and browsers, and offline/background sync remains limited. Glide does support App Interactions and custom workflows, but advanced or external workflows may need third-party integrations or APIs.

Pricing:

As of September 2026, the Free plan for personal projects includes unlimited drafts, one editor, and up to 25,000 rows. The Explorer plan starts at $19/month billed annually for small solo projects, and the Maker plan starts at $49/month for internal-tool builders who need more editors and a higher update allowance.

The Business plan starts at $199/month (billed yearly) and includes 30 users and 5,000 updates, with overage pricing of $5–6 per additional user and $0.02 per additional update. Row limits range from 25,000 to 100,000 depending on tier and data source type. Storage varies by plan, with 500MB on lower tiers, 500GB on Business, and custom storage on Enterprise.

FlutterFlow: Best for Flutter code export with design flexibility

FlutterFlow gives you a visual interface for building apps with Google’s Flutter framework, with pixel-level design control and exportable Flutter code. It sits between traditional Flutter development and template-based builders: You build visually most of the time and drop into code when you need to. AI generation runs through DreamFlow, a separate tool.

You can dial in specific brand guidelines or complex UI through the design system. Built-in animations, transitions, and state management handle more complex mobile interactions. If your app outgrows the visual builder, you can download the full Flutter codebase and keep working in VS Code or Android Studio.

Best for:

  • Teams that specifically need the Flutter framework for technical requirements or plan to hand off to Flutter developers later. Flutter’s cross-platform rendering fits when consistent UI across iOS and Android matters.
  • Projects requiring Flutter-specific packages, widgets, or libraries unavailable in other visual builders. Direct access to pub.dev packages expands what you can integrate.
  • Development workflows where exporting Flutter code for further customization is a core requirement. Agencies that hand off finished code to clients often need this escape hatch.
  • Apps where you need to work directly in Flutter’s widget tree. Fine-grained widget control matters for animations and custom UI.

Limitations:

FlutterFlow has a steeper learning curve than pure template builders, since you’ll need to understand Flutter’s widget structure and state management. You can export a Flutter codebase to work with outside FlutterFlow, but changes you make externally may not round-trip back into the visual builder.

Pricing:

As of September 2026, the free tier includes two projects, five AI requests per lifetime, and one editor. The Basic plan at $39/month (or $29.25/month billed annually) includes unlimited projects, 50 AI requests per month, one editor, code download, APK download, one-click Apple and Google Store deployment, up to 20 free subdomains, and one free custom domain connection.

The Growth plan at $80/month for the first seat (or $60/month billed annually) includes up to two editors, 200 AI requests per month, real-time collaboration, up to two open branches, Push to GitHub, and VS Code Extension. The Business plan at $150/month for the first seat (or $112.50/month billed annually) includes up to five editors, 500 AI requests per month, up to five open branches, up to three automated tests, Figma Frame Import, custom typography, and CLI Access.

Adalo: Best for small business apps with templates

Adalo gives you a visual multi-screen canvas plus templates and UI kits for common patterns like booking systems, directories, marketplaces, memberships, and simple commerce. You can prompt it to generate an app, or start from a template and connect your own data. It works best when your app fits one of these patterns and doesn’t need much beyond what the templates already offer.

Adalo publishes native iOS and Android apps, generating Android AAB files for Google Play alongside web deployment. It supports device features like geolocation and push notifications, but check current Adalo documentation before relying on camera or biometric authentication support.

Pre-built integrations for Stripe, Google Maps, and other popular services add common functionality without custom development.

Best for:

  • Small businesses building standard apps like booking systems, directories, or membership platforms. A yoga studio booking app or neighborhood directory maps directly onto Adalo’s templates and canvas.
  • Founders who want to start from either an AI-generated app or a template that closely matches their vision. Starting from a working scaffold beats a blank canvas when timeline is the top priority.
  • Projects where speed to launch matters more than deep custom design or unique workflows. Get to launch quickly, then iterate on what your users actually need.
  • Apps with straightforward monetization through subscriptions or one-time purchases. Standard Stripe integration handles most small-business billing.

Limitations:

Adalo’s performance can slow down as your database grows, so test load times with a realistic amount of data before you commit. Complex, logic-heavy workflows can also hit a ceiling, since Adalo’s visual logic builder is built for straightforward conditions instead of deep branching or custom automations. If your app doesn’t fit one of Adalo’s standard patterns, customization options are limited, and building something more unique can mean working against the grain of its templates and canvas.

Pricing:

As of September 2026, the Free plan includes zero published apps, unlimited test apps, one app collaborator, and 500 records per app storage. The Starter plan at $36/month (billed annually) includes one published app, unlimited test apps, one app collaborator, 5GB team storage, and unlimited app actions with no usage-based charges.

The Professional plan at $52/month (billed annually) includes two published apps, five app collaborators, and 25GB team storage. The Team plan at $160/month (billed annually) includes five published apps, 10 app editors, 125GB team storage, priority support, Xano integration, App and Collections API, version history, and white labeling. There are no per-user or per-action charges across tiers.

How much does it cost to build a mobile app?

Building a mobile app with an app builder costs a monthly platform subscription plus app store fees. The lowest paid tiers in this comparison start between $19 and $42 a month, native publishing adds $99 a year for Apple and a one-time $25 for Google Play, and usage-based charges grow as your app does. Hiring a team to build a native app from scratch often costs tens of thousands of dollars (or more).

Each of those pieces has its own math.

What you’ll spend on the platform itself

What you pay depends a lot on your publishing path. PWA-only builders tend to be cheaper, since they skip the app stores entirely, while native iOS and Android publishing usually pushes costs up. The lowest paid tier isn’t always the cheapest plan that gets you into the app stores:

Builder Lowest paid tier Lowest plan with app store publishing
Bubble Starter Web, $32/mo billed annually (web only) Starter Mobile, $42/mo billed annually or $49/mo billed monthly
Replit Core, $20/mo or $18/mo billed annually Check Replit’s current plans. App Store publishing is guided, but Google Play publishing isn’t supported yet.
Bolt Pro, $25/mo billed monthly None in Bolt. Native builds publish through Expo’s tools outside Bolt.
Thunkable Accelerator, $19/mo billed monthly Builder, $37/mo billed yearly or $59/mo billed monthly, with one live published app
Glide Explorer, $19/mo billed annually Not available (PWA only)
FlutterFlow Basic, $29.25/mo billed annually or $39/mo billed monthly Basic, with one-click Apple and Google Store deployment
Adalo Starter, $36/mo billed annually Starter, with one published app

Native publishing on any of these platforms also requires Apple’s and Google’s developer fees.

Fixed costs: Apple and Google publishing fees

Publishing native comes with fees you can’t avoid: $99 a year for the Apple Developer Program, and a one-time $25 for Google Play. Publishing to both stores costs $124 in your first year and $99 a year after that. Apple and Google set these fees themselves, so they apply no matter which platform you use (and can change whenever Apple or Google decides to).

Hidden costs to watch for before you commit

This is where a lot of first-time builders get caught off guard. Grow past a certain point and you might hit limits on storage, API calls, AI usage, or how many people can collaborate on your project. A plan that felt cheap for your first users can jump fast once you scale up, so check the next tier up before you commit.

How publishing and updates work after you build

Publishing turns your app from a test project into a product anyone can download from the app stores. On any platform, the process has four stages:

  • Developer accounts and store listings: Complete the required developer account setup with Apple and Google, and provide your store listing content. For traditional development, you also generate a signing key and upload your app through the Google Play Console or App Store Connect.
  • Testing: Testing reveals issues before your users run into them. A simulated device in a web preview catches layout and flow problems early, while testing on a real phone shows how push notifications and other hardware features behave.
  • Store review: Apple and Google review your app before it goes live, so build review time into your launch plan. Native apps go through this on every builder in this comparison.
  • Updates: Your work continues after launch. Major updates or native-code changes need a new build and another round of app store review, while platforms that support over-the-air (OTA) updates let you push minor changes like text edits and design tweaks without resubmitting.

On Bubble, you publish from the editor: Bubble packages the build, validates your developer keys and IDs, and sends the build to the app stores. Bubble’s OTA updates push supported minor changes, and users get them silently the next time they open your app.

On the Free plan, you can test with the Simulated device option in web preview. On paid plans, you can test on a real device with dev builds, which require an App Store or Google Play Store connection and stay synced with the editor.

Which mobile app builder is right for you?

Here’s a quick way to match your needs to the right platform:

  • Bubble: Choose it if you want to generate an app with AI and still change the logic and data yourself. One fully visual editor handles web and native iOS and Android apps, with a shared database and backend.
  • Replit: Choose it if you want AI to build your app in code and you’re comfortable reviewing what it writes. Agent handles the frontend, backend, and database, with a guided path to the App Store, though Google Play publishing happens outside Replit.
  • Bolt: Choose it if you’re comfortable with code and want a prototype quickly. Bolt writes a JavaScript app you can download or sync to GitHub, and native mobile apps publish through Expo’s tools outside Bolt.
  • Thunkable: Choose it if you want native store publishing for basic apps. It supports App Store and Google Play Store distribution for apps that fit its block-based logic patterns.
  • Glide: Choose it if a progressive web app meets your needs and you’re building from spreadsheet data. It turns Google Sheets or Airtable data into mobile-optimized PWAs and fits when you don’t need app store distribution.
  • FlutterFlow: Choose it if you need Flutter code export with design flexibility. It gives you visual customization for Flutter apps and access to code, which can help if you plan to hand the app off to Flutter developers.
  • Adalo: Choose it if your app matches standard business templates and you prioritize a quick launch. Its AI generation, visual canvas, and templates support use cases like booking systems, directories, and membership sites.

If you already have an app built with an AI coding tool, you can bring it into Bubble with universal import. Bubble generates a fully visual app you can keep building, including adding native iOS and Android apps.

Start building your mobile app

The cheapest platform isn’t always the best value. Hidden costs like storage limits, API caps, and scaling fees can erase the savings fast. The builder worth paying for gives you an app you can maintain and keep growing.

On Bubble, you build with AI without giving up control. The Agent gets you to a first version, and every part of what it builds, including the logic, data, and privacy rules, is visual and editable.

The app works the way you imagined, and you can change it as fast as your business changes. Use AI when you want speed or edit by hand when you want precision.

Build web and native mobile together in one project, with a shared database and backend, and one subscription covers both. Native app builds submit right from the editor.

Get started for free by describing your app to the Agent and shaping the plan together in a planning session. Bubble apps already transact more than $1 billion a year, and yours can keep growing on the same platform you start it on.

Frequently asked questions about mobile app builders

Do I need coding experience to use a mobile app builder?

No coding experience is needed for visual builders like Bubble, Thunkable, Glide, and Adalo, and on Bubble, the Bubble AI Agent explains what it builds in plain language, so you learn how your app works as you go. Replit and Bolt let you start by chatting with AI, but changing logic and data later means reading the code they generate. FlutterFlow’s advanced customization requires understanding Flutter’s widget structure.

What’s the difference between a native app and a PWA?

A native app is published to the App Store and Google Play Store and can use device features like push notifications, the camera, GPS, and in-app purchases, while a progressive web app (PWA) runs in the browser and can be saved to a home screen. PWAs skip app store review and usually cost less, but device access varies by browser and operating system.

What is the cheapest mobile app builder?

Among the seven builders compared here, the lowest paid tiers start at $19/month (Thunkable Accelerator and Glide Explorer), but Glide builds PWAs only, and Thunkable’s first plan with a live published app is Builder at $37/month billed yearly. If you publish natively, add Apple’s $99 yearly fee and Google’s one-time $25 fee, and check usage limits before you commit.

Can I build a mobile app for free?

You can start building for free on most of the builders here, including Bubble, where you can build and preview a mobile app on the Free plan with the Simulated device option. Publishing to the App Store or Google Play Store generally requires a paid plan, plus Apple’s and Google’s developer fees.

Can I build a mobile app with ChatGPT or Claude?

Yes, with the Bubble MCP (beta), available as Bubble’s connector in Claude and Bubble’s plugin in ChatGPT, you can build your Bubble app from those tools, and everything they build stays visual and editable in the Bubble editor. On their own, ChatGPT and Claude can write app code, but turning that code into an app in the App Store and Google Play Store is up to you.

Can I bring an app I built with an AI coding tool into Bubble?

Yes, with universal import, you can upload a .zip or .html file or import through the Bubble MCP (beta), and Bubble generates a new, fully visual app from it. From there, you keep building with the Bubble AI Agent or by hand, including adding native iOS and Android apps.

Will AI-generated code create maintenance problems later?

It can, because when you can’t read or edit AI-generated code yourself, every change goes back through a prompt or a developer, technical debt builds up as the app grows, and a December 2025 study found AI models’ debugging ability drops 60–80% after just two or three attempts. On Bubble, everything the Bubble AI Agent builds becomes visual workflows, data structures, and app elements you can inspect and change directly.

Can I export my Bubble app if I need it in code later?

Yes, the Bubble MCP (beta) connects your app to an AI agent like Claude Code or Codex, which rebuilds it in code you own and host. You can move your data through the MCP or a CSV or JSON export.
