Perplexity Health vs Open Wearables

Connecting 1.7M EHR providers via FHIR/API without building any hardware is exactly the right infrastructure play. If they open a developer API layer on top of this health data graph, every health app will want to plug in. The data moat here could be enormous.

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.

Perplexity has had data sourcing controversy before. Trusting them with your EHR and biometric data is a much higher-stakes bet than trusting them with web search. One breach, one data-sharing revelation, and the regulatory blowback would be severe — HIPAA exposure is no joke.

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.

Longitudinal personal health AI is the killer app that makes everyone a power user of their own data. When you can ask 'why was my HRV tanking in February?' and get a real answer, health AI stops being aspirational and starts being essential. Perplexity just claimed the territory.

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.

Generating pre-appointment summaries I can actually share with my doctor is the kind of practical health feature I've wanted for years. The UX of 'ask a question, get your data back in plain language' is dramatically better than digging through the Health app graphs.

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.
