a0.dev
AI mobile app builder for generating, testing, monetizing, and publishing React Native apps to iOS and Android.
About a0.dev
a0.dev is an AI-powered mobile app builder focused on turning app ideas into real iOS and Android projects. Its homepage positions the product around AI coding, one-click app publishing, integrated payments, growth analytics, and mobile testing, while the docs show a workflow that includes prompt-driven development, phone previews, native IPA/APK builds, App Store Connect setup, subscriptions, push notifications, deep links, and over-the-air updates. The strongest fit is a mobile-first builder who wants to move from idea to app-store-ready prototype without wiring together Xcode, Android Studio, Expo, payments, backend setup, and store submission from scratch. It is less suitable when the product is primarily a web app, when Android in-app payments are required today, or when regulated enterprise compliance and deep custom backend architecture are the main decision criteria. Buyers should treat the subscription credit limits as an adoption constraint, test native builds before relying on payments or push notifications, and compare a0.dev with visual builders, code-first Expo workflows, and other AI mobile app builders before committing a production roadmap.
Best for
Best use cases
A founder sketches a subscription app, generates the first mobile build, tests it on a phone, then prepares a native build for payment validation.
A local business turns menus, booking requests, loyalty rewards, or community updates into a branded mobile app without starting in Xcode or Android Studio.
A team uses the chat agent to add screens, connect Convex or Supabase data, configure push notifications, and review the generated React Native code before launch.
A creator prepares an iOS release by connecting App Store Connect, generating a build, checking TestFlight, and following the pre-submission checklist.
An operator ships a small fix after launch through the over-the-air update flow instead of rebuilding and resubmitting the whole app.
Compare before choosing
Compare with Rork when the main question is AI-native mobile generation and how each platform handles React Native output, app previews, and store submission.
Compare with FlutterFlow when you need a mature visual builder, Flutter output, or more visual control instead of a chat-first React Native workflow.
Compare with Expo plus Cursor when you have engineering capacity and prefer direct code ownership over an integrated prompt-to-store platform.
Compare with web app builders such as Bolt.new or Lovable if the product is primarily a SaaS dashboard or website rather than a mobile app-store release.
Features
AI coding agent
Generate and edit mobile app code through a chat workflow, including iterative changes such as adding screens, refining UI, and fixing implementation issues.
iOS and Android app building
Build mobile apps for both major app platforms, with a workflow designed around React Native-style mobile projects rather than generic website generation.
Phone preview workflow
Preview work on real devices through the a0 app for iOS or Expo Go for Android, with hot reloading for fast UI and interaction testing.
Native build testing
Generate IPA and APK builds when full native behavior is required, including payment validation and production-style app testing.
App Store Connect publishing
Connect Apple developer credentials, generate a build, submit it to App Store Connect, and continue through TestFlight and App Review preparation.
Monetization setup
Configure subscription plans and one-time purchases through the payment system, with Stripe support on web and Apple App Store support for iOS.
Backend and integrations
Use documented support for Convex, Supabase, deep links, push notifications, and generated configuration files when building more complete mobile workflows.
Over-the-air updates
Ship code updates after release through an OTA flow so small fixes and feature changes can reach users without a full rebuild each time.
Pros
- Clear mobile-first positioning with a prompt-to-app-store workflow instead of a generic website builder pitch.
- Official docs cover practical release steps such as App Store Connect setup, native build testing, payment setup, push notifications, and OTA updates.
- Useful for builders who need an integrated path across AI generation, testing, monetization, and publishing.
- React Native-style output and Expo-related testing make it more inspectable for developers than a closed black-box app builder.
Cons
- The official pricing page exposes many paid credit tiers but does not clearly explain every feature difference in the visible page copy.
- Payment testing cannot be completed in the a0 preview app or Expo Go; native builds or TestFlight are required for realistic validation.
- Android payments are documented as not supported yet, which can block mobile monetization plans that require parity across iOS and Android.
- The tool is a poor fit for web-first SaaS dashboards, deep custom backend systems, or teams that need mature enterprise compliance documentation before adoption.
