About this app

Welltory is your personalized health tracker app. Get more insights about your heart health with a smart heart rate monitor app: check heart rate, pulse and blood pressure, track health and stress. 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.

Studies show that our hrv measurement method is as accurate as ECGs (EKGs) and heart rate monitors. By simply measuring your hrv using your smartphone camera or watch, you can get personalized insights about your heart and health. Sync 1,000+ supported apps & gadgets, from Garmin to Reddit, to track your activity, sleep, productivity, nutrition, meditations, and more. Record your bp data and use our blood pressure checker analytics. Our AI will scan your data and track your symptoms for insights daily and gradually guide you to feel happier and healthier.

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

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.

You pay Premium, and every time open the app, an upgrade to lifetime "ad" is the first thing you see. Lacking features a journal should have. No ability to add anything after the fact. Adjust sleep at the source, it does not come through, and you can't edit it either. Without these abilities, true tracking of daily events is not consistent nor fully achievable.

Thanks for sharing. You can turn off push notifications in your phone settings — your subscription won’t change. Journal edits are limited, and sleep data comes from Samsung Health/Health Connect, so please check permissions. If it still doesn’t sync, contact us via Menu → scroll down → Report a problem.

I'm not sold on this app. I paid for the year subscription and felt the 3 day free trial was better than the actual paid version. It doesn’t track my sleep (it did with the free version) even though I have 3 apps that are connected that track my sleep. I've reached out to the customer service to report the issue and have not received any response. Also what it tells me about my heart rate seems pretty wonky.I really wanted to like it, but I'm pretty disappointed.
