Open Wearables is a self-hosted, MIT-licensed health intelligence platform that normalizes data from 10+ wearable devices — Oura, Whoop, Garmin, Apple Health, Polar, Samsung, Strava, and more — into a single consistent API. At 10,000 users, SaaS alternatives like Terra API charge $5,000–$20,000/month in per-user fees. Open Wearables charges zero. The platform goes beyond raw data normalization to include open health scoring algorithms for sleep, recovery, strain, stress, HRV, and VO2 max. Unlike proprietary scores (Oura's Readiness, Whoop's Recovery), every calculation is auditable and forkable. An MCP server lets Claude or any LLM query all connected client data and run scoring analysis directly — turning wearable data into structured health reasoning rather than a wall of raw metrics. Built by Momentum, a healthcare AI agency led by Bartosz Michalak, the stack runs on FastAPI + Flutter + Docker with HIPAA-ready architecture. A practitioner-facing layer is in progress for Q2 2026. If you're building health or fitness products that aggregate wearable data, the infrastructure economics here are genuinely game-changing.
Reviewer scorecard
“HealthKit API provides access to the most comprehensive health data ecosystem. Essential for health app developers.”
“The MCP server integration is the killer feature — querying a unified wearable data store through Claude without any custom ETL is genuinely powerful for health app builders. The HIPAA-ready Docker setup removes the scariest infrastructure concern. If you're building anything in health/fitness, this is the infrastructure layer you've been waiting for.”
“The health data aggregation across devices is unmatched. Apple's privacy-first approach builds trust.”
“Ten-plus device integrations maintained by a small agency team is a support nightmare — one Whoop or Garmin API breaking silently can corrupt months of health data. Also, 'HIPAA-ready architecture' is not the same as being HIPAA compliant — that requires a full security audit, BAA agreements, and ongoing compliance processes that an MIT-licensed repo can't guarantee.”
“Apple's health platform will become the most important personal health record. Clinical records integration is transformative.”
“Open, auditable health scoring algorithms are the missing piece in the wearables ecosystem. When Oura or Whoop's proprietary score doesn't match how you feel, there's no way to interrogate why. Open Wearables makes health intelligence transparent and forkable for the first time — that's a fundamental shift in who controls the interpretation of your biometric data.”
“For wellness content creators and coaches who want to build personalized recommendation flows, having one API that abstracts away which ring or watch a client uses is an incredible unlock. Stop building Oura-only apps and start building device-agnostic health products.”
