Open Wearables

The real move here is that Open Wearables is the first team dropping open scoring algorithms into the wild — not just the scores themselves but every coefficient, threshold, and weighting in the actual repo, so teams can audit, fork, and tune recovery metrics for specific populations instead of trusting device makers' black boxes. They've solved the wearable data plumbing problem by building one API that standardizes ingest from Oura, Garmin, Whoop, Apple Health, and more, which means health AI products stop rebuilding the same boring integration work and actually ship something. Free, self-hosted, and MIT licensed at 13,000 users with a #2 Day Rank is the kind of traction signal that makes real ones pay attention.
