Hey PH! We just went live.

Open Wearables is an open-source platform that turns raw wearable data into something actually useful. One API for multiple wearable providers, open scoring algorithms, and an AI engine that reasons about health data instead of just summarizing it.

Asking because we've shipped 220+ health tech projects at Momentum and the answer is almost always the same: wearable integrations.

Not the AI. Not the UX. Not the business model. The data layer.

Something we noticed: LLMs are surprisingly bad at health data out of the box.

Give Claude or GPT a week of sleep and HRV data and you get "Your average HRV was 45ms, slightly lower than last week's 48ms." Cool, I can read a spreadsheet too.

Something we kept running into across projects: wearable integration eats months and adds zero product value.

Every provider does things differently. Garmin sends XML. Whoop sends JSON but paginates differently than Oura. Apple Health needs on-device processing. Samsung has its own SDK. Different auth flows, different rate limits, different webhook formats.
