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 want to like this app. I love the interface and the charts it can give you - however, it will NEVER complete a reading! The progress circle gets all the way to the end and then says it lost connection. I have yet to get one single reading. I don't understand how it'll read all the way to the end then say it's not connected. I literally have my phone & watch beside each other. If this issue and actually get something to log, I'll change my rating because I think it has great potential

I was intrigued by the app during the free trial and upgraded to continue to evaluate it and see if I can use it effectively to improve my health. I'm not sure yet, but since upgrading the app has been nagging incessantly to upgrade the next level. It is incredibly irritating and tells me something I don't like about the dev. I want to keep using for the remaining subscription but I don't want to reward this constant nagging. I want an opt out or something to make it stop or I'll uninstall.

Worked great to start with but after a month low accuracy. Started using this after being recommended it by someone I work with. To start with it worked great and was useful. After a month on premium, I've seemed to lose all accuracy as every measurement says low accuracy score. It isn't my camera, it's been cleaned and I use it the exact same way. I haven't changed how I measure at all, it's just stopped working. Paused my subscription because I'm not paying if it doesn't even work
