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.

Sleep Flow is not just a bunch of random calming sounds for sleep. It's designed to relax your mind and improve your sleep quality. Every word and sound of it is backed by the science of sleep.

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.

edit: it took Samsung doing a major update until it was able to sync again. the major updates of Weltory since then have made it an even better experience than before the sync failure. 4 stars. P.S. one final sour note. Welltory still hasn't addressed the issue of correcting for broken sleep. Samsung Health will correct for it but not this app. for eg occasionally this app will say I slept for 2hrs or so even after a full nights sleep, with Samsung Health correcting its own record saying 6-8hrs.

Very poor app. Sync issues almost every time it's used. States it has no signal most of the time requiring phone and watch reset. Completely mucks up Fitbit tracking overnight resulting in missed and lost data from Fitbit. Woke up this morning after wearing watch to bed and there is ZERO data from overnight sleep and can't even do a measurement as it now says no signal. Both phone and watch paired properly. I definitely don't recommend this app. So many bugs and very expensive.

Hi, we're sorry to hear about your experience. For Fitbit issues, ensure your device syncs with its app and check Welltory's permissions in the source app. If sleep data is missing, try syncing again. For signal issues, reinstall the app and reboot your phone. If problems persist, contact us via Menu → Report a problem → Send.

most aggressively commercialised app I've ever used. it's quite good but not enough to justify the price. if you have sympathetic nervous system activation problems you should spend your money on somatic experiencing trauma therapy instead, wish I'd known before paying for this (and failing to cancel my subscription after giving I had several times...)
