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 10 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, Galaxy Watch5 Pro, Pixel Watch 2, and Pixel Watch 3, 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.

The only thing I don't like in this app is that the information displayed during the measurement is flipping so fast that no matter how fast reader you're, you still can't read a full statement, that makes it more stressful than informative which probably increases the stress during the measurement and probably adding an error to the metrics. once this is taken care of, I will give it 5 stars. Everything else is great.

Hi, thank you for your thoughtful review. We hear you about the fast-flipping information during measurements. While it’s designed to provide quick insights, we understand it might feel overwhelming. We'll share your feedback with our team. We're glad you enjoy the rest of the app and appreciate your support 🙂

I am amazed as to how accurate this app is. I was feeling tired and opened it up and it said my energy was low. It is probably my favorite health app so far! My only qualm at the moment is that I cannot figure out how to get the energy calendar with the color dots back like it showed in signing up. But that's small potatoes compared to how cool the app really is!

inconsistent. doesn't always pull data from other apps (sleep results especially). data is often incorrect, i.e. citing current data as baseline. I have the premium and cannot figure out how to cancel.edited to add, I've checked all connections. it works properly 90% of the time which leads me to believe it's not a set up issue. If you're ok with 90%accuracy you'll probably be happy with this app. for sleep the app literally takes my current sleep time and calls it the baseline. every single day
