Android Heart Rate Feedback App
Budget: $30 – $250 USD
I'm seeking an Android developer to create a prototype app that connects via Bluetooth to a fitness band (e.g., Xiaomi Smart Band 9 Active) and translates the user's heart rate into:
- Full-screen color changes based on BPM zones
- Real-time heartbeat sound feedback in headphones
- Metronome alert tones at dangerous heart rates
- Light ambient background music in safe zones
- Memory buffer (10 seconds) to detect sharp pulse changes
- User-defined thresholds for low/high BPM danger
- Display can be split for 2 users (2 devices, 1 screen)
- Graph of pulse history stored after each session
Bonus if you have experience working with BLE signals, Android audio playback, and simple UX. A full tech specification PDF will be provided.
