Cross-Platform App.

My REST-based backend is live and documented; what I now need is the Android and iOS front-end that brings it to users.
The apps are for the employees of a cleaning company. The product is a straight-forward app with four core capabilities

• Logged in Users can see their shift plan
• Users are get notified when their plan changes.
• Shift plan – a simple calendar-style screen that shows upcoming shifts pulled from the backend. Already finished shifts should also be shown.
• Time stamp capture – one-tap recording of start/finish times sent to my existing endpoints

User authentication is required (username/password). Once authenticated, every call must tunnel through the current API layer; no extra server work is needed from your side.

Feel free to build with Flutter, React Native, Kotlin Multiplatform or another cross-platform stack you’re comfortable with, as long as a single codebase produces both stores’ binaries.

Deliverables
1. Clean, well-commented source code in a single repository
2. Android (AAB) and iOS (IPA) release builds ready for store submission
3. Brief setup/readme and a recorded walkthrough so my team can run the project locally
4. One test build round (TestFlight / internal track) to verify flows before final hand-off

If you’ve shipped similar utility apps that handle authentication, push notifications and offline data sync, I’d love to see them and get this moving quickly.
