Open Wearables Release 0.4.3: Health Scores, Webhooks
Key takeaways
- Sleep Score and Resilience Score now compute natively inside the platform. First release where Open Wearables produces scored health output from the data it holds.
- Both scoring algorithms are open source. Every calculation is in the codebase, versioned and auditable. Open algorithms. Zero black boxes.
- Outgoing webhooks deliver real-time events to any HTTPS endpoint. No polling required.
- Both scores are in beta. Algorithms will change as data is gathered.
Open Wearables 0.4.3 is available on GitHub.
Health Scores (beta)
Sleep Score evaluates sleep quality across duration, consistency, and stage composition. Resilience Score uses HRV-CV (Heart Rate Variability Coefficient of Variation) as a readiness and recovery stability metric.
Both scores return through the existing API alongside the underlying wearable data. Use them as-is, build custom logic on top, or fork the algorithm and tune it for your population.
The algorithms are open source. If a score produces a surprising result, you can trace it to the exact inputs and formulas in the repo. This is the practical difference from closed-source scoring: Whoop and Oura deliver a number with no method attached. Open Wearables ships the coefficients.
Outgoing webhooks (beta)
Register an HTTPS endpoint and subscribe it to event types. When matching data arrives, Open Wearables delivers a POST with the full normalized payload. Processing happens in the background so webhook delivery does not block data ingestion. Dashboard shows delivery history and lets you retry failed deliveries.
What's next
0.5.0 completes the webhook infrastructure with incoming webhook support for Whoop and Suunto, and adds granular time-series queries to the MCP Server.
