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.

Everytime i take measurements, the app keeps telling me that it has low accuracy. I kept my body really still, not sure what else to do. My main problem is the UI, it's too complicated & overstimulating. Sooo many colors, texts, cards, points of attention. The first time i opened the app, i got bombarded with information popping up to be read. The tags UX also complicated and unclear. I wanted to try connection with garmin and that's not available even in trial period.

I like the interface and was interested at the start. But the integration with Fitbit is quite bad. Half the time it doesn't transfer data, or data is incorrect. For me the premium was a bit of a disappointment. So for free it's a good app, but not worth paying for. Update: after a month of messaging back and forth with Welltory, the app still doesn't work properly with my Fitbit. A pity and lost my confidence.

Welltory: heart-rate monitor & blood pressure log

Sanne, we're sorry for your unsuccessful experience with Fitbit! We understand it can be frustrating and work hard on improving the integration. It's a complicated process of development, it has a lot of steps, such as analyzing if data is reliable and filtering out unreliable figures. We hope that you stay tuned and turn to us with any questions.

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
