FAQ
We develop for Apple Watch (WatchOS), Wear OS (Android), and custom BLE devices. We also build companion apps for Fitbit, Garmin, and other fitness platforms via their SDKs.
Yes. We have experience with medical BLE devices including pulse oximeters, ECG monitors, and glucose monitors, with HIPAA-compliant data handling.
We implement robust reconnection logic, background BLE scanning, data buffering during disconnections, and user-friendly pairing flows tested across multiple phone models.
Health-related apps may require additional review for medical claims. We help prepare the required documentation and ensure compliance with Apple Health and Google Fit guidelines.
