If your Wear OS watch (version 3.0 or later) isn’t syncing data with our app, most of the time the issue can be fixed with just a few quick steps. It’s worth going through them one by one - often the cause is just a small setting or a missing update ⌚️
💜 Start with permissions and apps
Make sure you have the Health Connect app installed and enabled. You can find it in your phone’s settings (Settings → Health Connect). In its menu, go to App permissions, select Radiance, and enable exactly the data types we sync — workouts, heart rate, steps, sleep, etc.
If you’re using Google Fit or Mi Fitness/Zepp Life, check that they also have permission to read the same data types.
💜 Check your Google Fit or Mi integration
In Google Fit, open Settings and make sure Health Connect integration is turned on and data reading is allowed. Also double-check that you’re signed into the correct Google account — sometimes data ends up on a different profile.
For Mi Fitness or Zepp Life, open the Health Connect connection section and see which data types are actually supported — this can vary by region and app version.
💜 Keep the app running in the background
This is one of the most common reasons for sync problems. In your phone’s battery settings, disable optimization for our app, Health Connect, Google Fit, and Mi Fitness/Zepp Life (“Don’t optimize” option).
If you’re using a Xiaomi phone with MIUI, make sure Autostart is on, battery mode is set to No restrictions, the app is locked in Recents (lock icon), and background activity is allowed. Also turn off any aggressive power-saving modes or “Cleaner” apps.
💜 Check if your data is actually being saved
Go to Health Connect → Data & access → Browse data and see if entries from our app are visible. If they are, but they’re not showing in Google Fit or Mi, try restarting those apps, signing out and back in, clearing the cache (but not the app data), and temporarily disabling and re-enabling Health Connect permissions for those apps. This often forces a fresh sync.
💜 Look at Bluetooth and connection
Make sure Bluetooth is turned on and stable on both your watch and phone. Sometimes simply turning Bluetooth off and back on, or restarting both devices, can solve the problem.
💜 Check for updates
Ensure you have the latest versions of all apps: Radiance, Health Connect, Wear OS, Google Fit, and Mi Fitness/Zepp Life. If none of the above helps, you might consider resetting your watch to factory settings and pairing it again with your phone.
