Health Connect
Note: this part of the app comes with a licence. The free edition covers injections.
Health Connect is Android's shared store for health data. Watches, rings, scales and health apps write to it, and this app reads from it. Any device whose app writes to Health Connect works.
Turning it on
- In your watch's app, allow it to write to Health Connect. If you can't find the setting, go to Android Settings → Health Connect → App permissions, pick that app and allow it to write the data you want.
- In this app, go to Health → Setup and switch on the data you want: resting heart rate, heart-rate variability, sleep, steps, weight, body fat, calories and so on. Everything is off until you choose.
- Tap Connect and allow access in Health Connect.
- Sync your watch with its app. Data reaches Health Connect after the watch's app has it.
The app reads up to a year of history the first time, then keeps it up to date. It never writes to Health Connect.
When a measure isn't shared
Not every watch shares every measure with Health Connect. If yours doesn't share resting heart rate, the app works it out from your heart rate readings (the lowest 30-minute average each day), so it can differ a little from the number in your watch's app. For this, switching on resting heart rate also asks for heart rate access.
Past data
Health Connect only lets apps read data from 30 days before you first gave access, unless you allow Access past data. The app asks for it when you tap Connect. If it's off, Health → Setup says so: tap Update access, or go to Android Settings → Health Connect → App permissions and turn it on.
Where the data shows up
- Health → Overview: today's numbers and 30-day trends
- Health → Trends and Body: longer charts, and weight and body composition
- Readiness and the Weekly report: see those pages
Missing data?
Check that your watch's own app is set to share with Health Connect. In Health Connect, open App permissions, pick your watch app and allow the data types. Then tap Sync now in this app.
