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.

i purchased one year subscription. it still shows ad's few times a day for lifetime subscription. even year subscription would not worth it for lot of people. it's not bad if it was free. Data more or less the same you measure heart rate variability and their AI assume some stuff. Good buti would recommend do not purchase! it's interesting for few days after that gets Boring.

App appears ok and contains a lot of information, however it isn't accurate and constantly showing notices about random items. One example, I left my watch on the charger overnight, put it on in the morning, 2 hours later this app said I needed to get some sleep because I'm exhausted. I had considered purchasing it, however the cost is too high for what is offered. The 3 day trial only shows a portion of the app, but for me it just wasn't enough to get me to accept the overpriced subscription.

Hi, thank you for your thoughts. Our app analyzes your data to provide insights, but please note that HRV metrics have accuracy margins and depend on consistent data input. The free trial offers a glimpse of Premium features, and our pricing reflects advanced algorithms and research. If you have further questions, visit https://help.welltory.com/.

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
