OpenStrap analytics

recovery, strain and sleep from a WHOOP band's 1 Hz stream

What is OpenStrap analytics?

OpenStrap analytics is an open-source, pure-Dart library that computes recovery, strain, sleep and related scores from the 1 Hz data a WHOOP 4.0 band exposes: beat-to-beat intervals, heart rate, three-axis acceleration and relative skin-temperature, SpO2 and ambient-light channels. It is deterministic, runs on the phone with no cloud, and uses only published methods that are listed with citations.
