Already loved by 16 million users, quoted by Johns Hopkins University, Harvard Medical School, TechCrunch, Product Hunt, Lifehacker and others.

Our symptom tracker analyzes heart rate variability (hrv) — a heart health marker backed by over 20,000 studies on PubMed — to assess your heart health and overall wellness.

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.

App looks good and plenty of analysis available (if you upgrade to premium). However, I have doubts on the reliability, and looking at the reviews, price is way too expensive compared to the customer service provided. october 17 edit: the last update made previous data completely inaccessible, with just a home page for measurement. No access to properties, and option to delete your account, unless you pay premium.

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

Hi, thank you for your feedback. We're sorry to hear about the trouble with completing readings. To improve accuracy, ensure your Samsung Watch fits snugly, sensors are clean, and you're still during measurements. If the issue persists, please send us a bug report via Menu → Report a problem → Send, so we can assist further.

Amazing customer service! I had this app for a year and it was great. Unfortunately, I am unable to continue to pay for it. I was charged on my credit card and advised them I needed to cancel it and get a refund. They were amazing and facilitated my request with in minutes. Very professional and understanding and zero hassle with the cancelation and refund. Very appreciated!
