Wear OS watch app

Our Wear OS app allows you to set a tile on your watch for easy access to your latest measurements and includes complications that enable you to quickly start a new measurement directly from the watch surface.

The Welltory Wear OS app is compatible with Samsung Galaxy Watch4, Galaxy Watch4 Classic, Galaxy Watch5, and Galaxy Watch5 Pro, but it is not compatible with other Wear OS devices.

NOTE
Heart rate monitor may cause hot LED flash. Try keeping your finger 1-2 mm away from the flashlight or lay just a tip of the finger on the flash or alternatively cover the flash with one half of the fingertip.
Welltory can only measure your HRV and detect heartbeats. We cannot measure blood pressure and any other vital signs through the phone camera. Also the app is not a substitute for ekg interpretation. Always consult your doctor if you feel physically unwell.

This is an awesome app! It really helps my husband track his energy levels and what's going on with his sleep, etc. That's why I got it. However, it was much harder to set up as an Android user, though, they are probably making improvements all the time. My husband's iPhone experience was much easier as far as connecting all the health apps together and making sure they were still tracking and sharing the data. Overall it's a really cool app. I also like the little daily suggestions.

Hi, thanks for sharing such a thoughtful review. We’re glad the app is helping you and your husband, and we hear you about setup on Android. Android devices rely on Samsung Health or Health Connect, so syncing can take a bit more work. Happy you’re enjoying the daily tips 🤩

Overall, I like this app, but it sometimes says contradictory things. For example, the forecast will say full steam ahead, but the indicator for physical activity and everything else says go easy or limited. I've written support twice and never received a satisfactory explanation. Also, I find it annoying that I was asked to rate the app - and it automatically defaulted to 5 stars at first even though I selected only 4 stars. Minor pet peeve - but as you can guess truth is important to me!

Hi, thanks for the thoughtful review. Different parts of the app reflect different body signals, so mixed messages can happen when your systems aren’t fully aligned. If you’d like us to check your case, please contact us via Menu → Report a problem. Thanks also for flagging the rating pop-up — we’ll pass it to the team.

Honestly, I really like this app and it was one of my most used until something happened with security updates a few months back. Now it no longer connects directly to my Google Pixel 2 watch and the camera readings are more often than not too poor to be of use. Now, I don't even use it anymore. I can't afford to waste money on a service that no longer serves. I'll hold on to the app for a bit longer in case things change, but I'm not holding my breath anymore and am looking for a new app.

Thanks for sharing this. HRV measurements from Pixel watches are currently unavailable due to limitations on Google’s side. We’re working with them on this, but part of the solution depends on Google. As soon as there’s progress, we’ll update users. We appreciate your patience and hope to support your setup again soon.
