Open Wearables pushes wearable scoring and webhooks

Open Wearables has started generating its own sleep and resilience scores from raw wearable feeds, shifting the product from data plumbing to scored health output. (themomentum.ai) Version 0.4.3 shipped on April 14, 2026, and added native Sleep Score and Resilience Score alongside outgoing webhooks for real-time delivery to HTTPS endpoints. The company said both scores are in beta. (themomentum.ai) The release post said Sleep Score uses duration, consistency, and sleep-stage mix, while Resilience Score combines heart rate variability, resting heart rate, and sleep quality into one readiness number. Open Wearables returns those scores through the same application programming interface as the underlying device data. (themomentum.ai) Wearable platforms already produce their own scores, but they do not use the same definitions. Open Wearables said its goal is one normalized score across devices including Apple Health, Whoop, Oura, Garmin, Samsung Health, and others. (openwearables.io) That matters for teams building coaching, wellness, or clinical software on top of mixed device fleets. Open Wearables markets the scoring layer as open source, self-hosted, and auditable, with algorithms that can be forked or tuned for a specific population. (themomentum.ai) The webhook piece addresses a basic infrastructure problem: polling is wasteful. A December 3, 2025 GitHub issue said developers had to repeatedly hit endpoints such as heart-rate and workout routes just to detect new data, and the new webhook system pushes events when data arrives. (github.com) The company has framed that audit trail as a differentiator from vendor scores. Its April 15 release post said every calculation method is versioned in code, so a team can trace a surprising score back to inputs and formulas instead of accepting a black-box number. (themomentum.ai) The normalization problem has been visible in the project’s public issue tracker for months. A January 22, 2026 issue proposing a custom sleep score said Apple, Garmin, and Whoop each expose their own “often black box” values, which makes cross-device interpretation harder. (github.com) Open Wearables’ GitHub repository also shows active work on provider-specific semantics, including recent issues on sleep-score migration, resilience scoring, webhook handling for Whoop, and clarifying sleep-duration field semantics across providers. The repository showed about 1.3 thousand stars on April 18, 2026. (github.com)
