Overview
Consumer health app syncing with BLE wearable devices for activity tracking and wellness insights. Features responsive Flutter Web dashboards, geofencing events, and ObjectBox caching for offline resilience.
Challenge
Consumers expect a wearable to 'just sync' in the background, but continuous BLE streaming, battery life, and offline resilience pull against each other on real-world phones.
Solution
Implemented background BLE sync with an offline-first ObjectBox cache, geofencing-driven events, and a responsive Flutter Web dashboard so activity, sleep, and trends stayed current without draining the device.
Key work
- BLE wearable device pairing and continuous data sync
- Activity recognition and workout session logging
- Geofencing-based location events and notifications
- Responsive Flutter Web dashboard for analytics
- Offline-first architecture with background BLE sync
- Step counts, sleep tracking, and activity trends
