FlutterFlow BLE Fitness App

I’ve started designing a cross-platform fitness application in FlutterFlow and now need a specialist who can take it from prototype to a production-ready build that streams Bluetooth LE data flawlessly on both iOS and Android.

Core scope
• Real-time activity tracking must stay buttery-smooth while heart-rate and step-count packets arrive over BLE.
• The app must pair with common heart-rate monitors and fitness bands; automatic reconnection and background streaming are essential.
• Users plan workouts, start a session, then watch live metrics (heart rate, steps) update instantly on a clean, responsive UI. After each workout they should be able to review a timeline and basic analytics.

Tech specifics
I’m committed to FlutterFlow for UI and state management, but I’m open to your preferred Dart plugins (e.g., flutter_reactive_ble, flutter_blue_plus) or custom platform channels if that yields a more stable connection. The final build has to clear the current App Store / Play Store Bluetooth permission requirements.

Deliverables
1. FlutterFlow project file with integrated, documented BLE logic.
2. Signed iOS & Android builds ready for TestFlight / internal testing.
3. Short write-up or Loom walkthrough showing how to add new BLE characteristics or workouts in the future.

Acceptance criteria
• Stable connection: <1 % packet loss while streaming heart-rate data for 30 minutes on both platforms.
• UI latency: metric cards update in under 300 ms after data arrival.
• Code review passes Flutter analyze with zero errors or warnings.

If this sounds like your wheelhouse, let’s get it moving—looking forward to seeing what you can do.
