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.

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.

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 downloaded this based on some positive reviews. I am, to say the least, underwhelmed. The app started immediately spitting unverified data at me as though it was cannon. No questions about daily life or confirmation of data points. (other than weight, height and age. Even after tweaking the settings it's still telling me I've only slept 3 hours because I woke up and got a snack. Do better. There are other free apps that track my daily activities with better precision.

Thanks for sharing. We understand how frustrating it feels when data doesn’t match your day. Welltory reads info from Samsung Health/Health Connect — if sleep looks off, it’s usually from the source app. We don’t create data, only interpret it. Please check syncing/permissions or send a report via Menu → scroll down → Report a problem → Send.

If I could give them zero stars, I would, but I can't it was working well and it was a five star app to the point where I started to pay for the paid version. the paid version was phenomenal until they started charging me to make the app. Run like the free version. I reached out the customer service multiple times and all they had to tell me. Was that there was no account with the email? Which is funny because I signed up for the pro version through Google itself. stick to free paid=free 😑

Thanks for sharing this. If your Premium features look like the free version, please log out of Welltory, reboot your phone, and then log back in with the same account you used to make the purchase. If in‑app support isn’t working for you, write us at support@welltory.com from your Welltory account email so we can help check your subscription.
