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.

This app is actually pretty amazing, but over time it's become pretty inconsistent. Certain measurements dissappear, the analytics pull from the wrong day (eventually correcting), or manual measurements finish and never show in the log. I also don't love paying for no ads/premium and then getting pop-ups, even if it's an ad for the app itself. It's so close to being amazing, and when it has worked consistently it has been a great help.

Thanks for the thoughtful review, and sorry the app’s been unreliable. For missing or delayed data, please check sync and permissions in Samsung Health or Health Connect, then reinstall the app and reboot your phone. To turn off phone alerts, go to Android settings. Please report details via Menu → Report a problem → Send.

It has a bunch of "interesting" numbers and bells and whistles with no real substance. It seems like an app that thinks because there's lots of "information" there's value. There is no value in the information not being put together cohesively. The app needs a lot of polish before they can charge the kind of prices they are wanting.

Thanks for the candid review. We hear you: health data is only useful when it forms a clear picture. Welltory connects signals like HRV, sleep, and stress into reports and check-ins, and your note about cohesion and polish is fair. We offer both Free and Premium options.

I've used Welltory for two years, but no more. The app continues to be misleading by saying it can connect to meditation/mindfulness apps, when it can't. Talked to customer support about this A YEAR ago and got "thanks for the feedback". One year on, no change. It can't read mindfulness/meditation data because their Health Connect schema does not to request the READ_MINDFULNESS permission scope. Also agree with other reviewers about the annoyance of the Lifetime ads after purchasing Premium.

Thanks for sharing this and for sticking with us for 2 years. We’re sorry the meditation import via Health Connect still feels misleading. We’ve passed your note on to the team. Regarding Lifetime offers, please contact us via Menu → scroll down → Report a problem → Send, and we’ll help disable them.
