Wear OS devices

Sleep tracking with Wear OS device requires a companion app installed from the Play Store on the watch.

All Wear OS devices can monitor sleep tracking movement and collect HR.

Some wearables can also collect SpO2 data - for more details, please see the chapter on oximeters and SpO data. Currently, Ticwatch Pro 3, Ticwatch E 3, and Fossil Gen 6, have integrated SpO2 data.
If you have a Wear OS-based wearable with Spo2 sensor, that is not on the list, please let us know. We can adjust the parameters and integrate the sensor on other watches too.

Supported versions of OS
  • Android Wear 1.0

  • Wear OS 2.0

  • Wear OS 3.0

1. How to set up

  1. Make sure the watch is connected to the phone.

  2. Go to app list on your watch, select Play Store.

  3. Find Sleep as Android and select Install.

  4. After the companion app is installed, you can enable the connection in Settings → Wearables → Use wearable → Wear OS.

  5. Test the connection in Settings → Wearables → Test sensor - you should see a graph reacting to your movement (a short delay is normal, data are sent in batches).

  6. For HR data, enable Heart rate monitoring in Settings → Wearables.

FAQ

Cannot install app on Wear OS device

Sleep tracking with Wear OS device requires a companion app installed from the Play Store on the watch.

How to get there:

  1. Make sure the watch is connected to the phone.

  2. Go to app list on your watch, select Play Store.

  3. Find Sleep as Android and select Install.

  4. After the companion app is installed, you can enable the connection in Settings → Wearables → Use wearable → Wear OS.

  5. Test the connection in Settings → Wearables → Test sensor - you should see a graph reacting to your movement (a short delay is normal, data are sent in batches).

Note Sleep tracking collects data the night and they are analyzed in real-time. This means the watch must stay connected with BT during sleep tracking.

Do you support / integrate my device?

For all currently supported devices, check out list of compatible devices.

If you’d like us to integrate another device, please add it as a suggestion to our suggestion forum. Also please check whether the device has an API so we can integrate it.

My watch vibrates only once

On Wear OS platform and ONE UI Watch (Galaxy Watch 4 + 5), we use gentle vibrations for even more natural wake up.
It starts with a single vibe, another in 30s, than again in 20s and so on. After few minutes the vibrations will be continuous.

If you are worried this won’t be enough, you can set a delayed start of alarm sound on the phone. And there is always the backup alarm.

Samsung Galaxy Gear - Watch app stuck on "Start tracking"

This can be a result of multiple things, so please make sure to do the following troubleshooting:

  1. Make sure you have Sleep as Android Gear Addon installed on your phone

  2. It can happen that the addon cannot be started by us if it was force stopped previously. In that case please go to Play Store app on your phone, open addon page tap on “OPEN”.

  3. Opt out of any battery savers that you might have on your phone, for all involved apps (Sleep as Android, Sleep as Android Gear Addon, Samsung Accessory Services) – to find out how to do that, please consult dontkillmyapp.com

  4. Samsung Accessory services sometimes misbehaves and prevents connection to the watch for 3rd party apps. Please uninstall and reinstall it.

Tracking starts on its own

  1. Please make sure that you are not accidentally starting the Sleep as Android app from your watch. This would start sleep tracking immediately.

  2. Make sure you are not using automatic start of sleep tracking in Settings → Sleep tracking → Start sleep tracking.
