About

Terra connects 500+ wearables and health apps through one API and webhooks: activity, sleep, body, heart rate and nutrition data. Apple Health, Samsung Health and Health Connect need its mobile SDKs, and Garmin, Whoop or Strava need your own developer credentials. Paid plans only.

What you can do with it

Sync sleep, steps and heart rate from users' Garmin, Oura and Whoop devices
Read Apple Health and Health Connect data through Terra's iOS and Android SDKs
Let an AI agent read a user's wearable health data through Terra's MCP server
