What Do You Get in a Native Android Project?
A real Android app built with Android's own language, tools and components. Mention Android, Google Play or Kotlin in your first prompt and Fastshot starts a native Android project.
Kotlin and Jetpack Compose
Screens are written in Kotlin with Jetpack Compose and designed with Material 3 components.
Live Android emulator
The editor runs your app on a live Android emulator. Tap and type in it like a phone, with Android's Back, Home and Recent apps buttons.
AI that tests its own changes
The AI tries each change on its own copy of the app, including location, notifications, reminders and home screen widgets.
Managed Supabase backend
Connect a managed Supabase backend from the chat or the Backend tab. The AI moves the app from sample data onto it.
Email and Google sign-in
Add sign-in with email and password, and with Google, on top of the backend.
AI features, no API keys
Chat and text, image analysis, image generation and editing, and speech to text run through Fastshot's AI gateway.
APK, AAB and test builds
Builds usually take about 7 minutes. Install by QR code, or share a test build that reports crashes back for the AI to fix.

Can I test a Kotlin app without Android Studio?

Yes. Fastshot builds the AAB that Google Play takes and publishes it to the Internal, Closed, Open or Production track you pick. Android builds usually take about 7 minutes. See how to publish an app to Google Play.
Do AI features in a Kotlin app need an API key?
No. Chat and text, image analysis, image generation and editing, and speech to text run through Fastshot's AI gateway, so the native Android app needs no API key for them. Ask for the feature in chat and the AI builds it into the app.
