About this gig

Looking for a native Android app - phone, tablet or Wear OS watch - built by a developer who has actually shipped one?


I independently shipped a live fitness app on the App Store and Google Play (iPhone + Apple Watch + Android, 9 languages). I build with Kotlin / Jetpack Compose / Flutter / React Native - native or cross-platform, your choice.


What I can build for you:

- Custom Android apps from idea to Google Play release

- Clean, modern UI following Material Design 3

- REST API integration (login, payment, push, maps, chat)

- Backend with Node.js / Python / PHP + MySQL / PostgreSQL / Firebase

- Wear OS companion apps with health sync and notifications

- Ad network integration and in-app purchases


Packages:

- Basic: simple app, up to 5 screens

- Standard: complete app up to 8 screens + Play Store submission

- Premium: full-stack with backend, admin panel, ads and Wear OS companion


Message me before ordering - I'll scope your idea for free and confirm the right package. Larger scopes are quoted via custom offer. Need iOS too? Ask for a bundle quote.
