atria

Atria is an open-source iOS application designed for local data collection and analysis using a WHOOP strap, eliminating the need for official cloud services or subscriptions. It offers features such as live heart rate monitoring, sleep and workout tracking, HealthKit export, and customizable metrics, allowing users to leverage their straps for honest local metrics while maintaining data privacy. The app communicates directly with the strap over Bluetooth LE, ensuring all data remains on the device.
