Product description+
Smart rings settled on health tracking and stopped there — and every maker locked the sensor data behind a membership. The Ring is the same proven form factor with a sapphire PPG window, a documented BLE profile, and firmware you can build. Use the reference app for sleep and readiness, or pull raw interbeat intervals into your own pipeline. Dictation ring? Prayer-schedule ring? Two-factor ring? That is what an SDK is for.
