NOOP

NOOP is an offline companion app for WHOOP straps that keeps biometric data on the user’s own device. It pairs with supported straps over Bluetooth and stores readings locally in SQLite instead of using a cloud account or subscription. The app can read data such as heart rate, R-R intervals, temperature-related values, respiration signals, battery information, and events, depending on device support. It also imports WHOOP CSV exports, Apple Health exports, and nutrition CSV data to build a local history. NOOP computes metrics such as recovery, strain, HRV, sleep, workouts, trends, and correlations using transparent on-device analytics. It is an independent, unofficial interoperability project for users who want local-first access to their own wearable data.
