HealthKit Wrist Cooling

Automated comfort trigger. Reads Apple Watch sleeping wrist temperature baseline and triggers cooling routines when you run hot at night.

Apple HealthKit Read-Only

Dual Protocol Engine

Custom native drivers for both Bosch PointT REST APIs (OAuth PKCE) and real-time Bacon AWS IoT MQTT 5 binary device shadow sync.

PointT & Bacon MQTT 5

Zero Password Exposure

OAuth PKCE authentication ensures betterBCool never handles or stores your Bosch password. Plus built-in offline simulator mode for hardware-free testing.

Wrist-Temperature Night Cooling

Apple Watch produces aggregated appleSleepingWristTemperature samples during sleep tracking. betterBCool calculates a multi-night baseline and triggers comfort cooling whenever your body temperature elevates beyond your chosen threshold.

Samples evaluated for up to 18 hours
Requires 3 prior samples before engaging
100% read-only HealthKit permissions

FeverFrida BLE Explorer & Labs

Contains exploratory BLE decoder tools and CoreBluetooth inspectors (FeverFridaKit) built to research continuous wearable temperature sensors (WT701).

Isolated exploratory decoder target
Deterministic test fixtures without hardware
Strict sanitization for telemetry exports
