Hello @phiomet, I can confirm I also do not see the app in the Play Store… I trying to figure out what is happening. In the mean time the app can also be sideloaded from:

This is the latest version:

Hello, I hope I have fixed this 100% in BETA channel and the app is now 5% staged roll out to production…

So instead of side-loading you should also get the update by joining the BETA channel…

Tod o this, please first join our BETA Testers group at:!forum/sleep-as-an-droid
That you can opt-into the BETA at the following address:
Or simply by visiting our Play Store listing and tapping “Join BETA”

Also I have updated the Downlaod section with the latest version of the app 5.2:

Hello, I did just test that jointing the BETA on the Play Store after joining the Google Group (see above) did instantly made the Wear OS app visible on my watch…

Sorry for the issues. this should be fully resolved also in production in matter of days…

I just installed latest beta and watch app now appears on play store and now installed on watch. So hopefully everything will be working fine again. Thank you for your speedy response.

@medium2spirit big thanks for letting us know and confirming this!

I have an older samsung watch. Starting to think about a new device that’ll give me spo2 readings. I use a bipap and I sleep poorly when the mask is starting to get old. I’d like more data that might help me keep a better handle on that and distinguish between internal health issues and external equipment effectiveness. Is the latest samsung watch good for monitoring blood oxigenation or would something like Go2sleep be more effective? What’s the best device, please?

did you manage to make you Galaxy Watch fully fonctionnal with Sleep as Android ?
Sleep and 0² level recording, etc?
Merci pout votre attention
