Wearable Health Data Platform
All your health data.
One unified API.
MTH Health connects wearable devices from Fitbit, Garmin, and WHOOP into a single, normalized data layer — so you can build health experiences without managing dozens of provider integrations.
How it works
Connect providers
Enable Fitbit, Garmin, or WHOOP for your application through the admin portal. Each provider uses secure OAuth to authorize data access.
Users link devices
Your users authenticate with their wearable accounts. MTH Health handles the token exchange, storage, and automatic refresh.
Consume unified data
Access sleep, activity, heart rate, recovery, and more through a single normalized API — regardless of the source device.
What you get
Multi-provider support
Fitbit, Garmin, and WHOOP today — with more coming. One integration covers all devices your users wear.
Normalized data model
Sleep stages, activity metrics, heart rate, recovery scores, and nutrition all follow the same schema regardless of provider.
Health scoring engine
Built-in scoring algorithms turn raw wearable data into actionable health scores your users can understand.
Multi-tenant architecture
Isolate data per organization and app. Manage tenants, applications, API keys, and user roles from one admin portal.
Automatic sync
A background worker continuously polls provider APIs to keep user data fresh — no cron jobs or manual triggers needed.
Secure by design
OAuth tokens are encrypted at rest. API keys are scoped per application. Admin access uses passwordless OTP authentication.
