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.

I downloaded this based on some positive reviews. I am, to say the least, underwhelmed. The app started immediately spitting unverified data at me as though it was cannon. No questions about daily life or confirmation of data points. (other than weight, height and age. Even after tweaking the settings it's still telling me I've only slept 3 hours because I woke up and got a snack. Do better. There are other free apps that track my daily activities with better precision.

Welltory: heart-rate monitor & blood pressure log

Thanks for sharing. We understand how frustrating it feels when data doesn’t match your day. Welltory reads info from Samsung Health/Health Connect — if sleep looks off, it’s usually from the source app. We don’t create data, only interpret it. Please check syncing/permissions or send a report via Menu → scroll down → Report a problem → Send.

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.

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 🤩
