  1. [R1] Welltory 1/5 · US Not able to cancel: The data provided by the app is very interesting, but can be overwhelming. Giving low stars because I’m not able to turn off auto renew for my yearly subscription. I sent a message via their contact form and have not had a response, I will have to cancel my credit card. They also really push buying lifetime access. I signed up for the annual subscription because it claimed I wo
  2. [R2] Welltory 5/5 · US Good product: Just checking to see if it was accurate. It was. It recognized that I was in Afib.
  3. [R5] Welltory 5/5 · US Knowledge is power.: Knowledge of our own engine is survival.
  4. [R6] Welltory 3/5 · US Monetization tactics overwhelming and disruptive: I have a premium plan and am CONSTANTLY disrupted with nudges and prompts to upgrade, review the app, and engage with the app (“have you checked your nervous system in the last 15 minutes?”) The PMs should focus more on how to make this data useful for me and surfacing it in helpful ways.
  5. [R3] Welltory 3/5 · US Accuracy?: I’ve had this app for quite a while now . I don’t really feel it’s necessarily accurate a lot of the times. For instance, it tells me that I’m under huge stress when I’m taking a nap in my own bed at home as usual…
  6. [R13] Welltory 2/5 · US blah: it doesn’t really track as much as it says, and doesn’t connect easily to other apps.
  7. [R16] Welltory 1/5 · US scam: I would have given you -4 stars if I could. You guys put stuff on this app that I did not do but you say I did?? Very not worth even trying this app!
  8. [R15] Welltory 3/5 · US Too much: This app collects too much information and is too much of an invasion of my privacy. The information is too overwhelming to be useful.
  9. [R17] Welltory 4/5 · US Great Information But…: This is a really phenomenal app for helping measure health statistics, but the presentation can be a little overwhelming. There’s a lot of information isn’t always as well organized as hoped for. There’s a lot of requests to pay for the permanent membership. Real time HRV alerts would be great.
  10. [R18] Welltory 3/5 · US Money is time…: Too much information to provide a useful tool for personal health; for me, it takes too much time and focus on a daily basis. I also feel like I’m getting too many suggestions to look at too many different measures (I’m talking about within the app, as notifications can be silenced). I have tried to use it, but it takes so much time to review the multitude of measures and data. I
  11. [R9] Welltory 3/5 · US Voracious Ads - Even with Premium: I like so many things about this app, but even with a monthly or yearly Premium subscription it is still constantly pushing me ads to buy Premium. Every, single, time I open the app the first screen is why a lifetime membership is best or here’s a promo for 50% off. Even after closing that, a banner to upgrade always lives at the bottom of the app. I have premium
  12. [R12] Welltory 3/5 · US Expensive: This is an expense app for premium and it still has a TON of ads trying to get you to upgrade. Super annoying. Hard to follow the information because there is so much data to try to navigate.
  13. [R19] Welltory 2/5 · US I would love this app but there’s so many pop up ADs even after paying for it.: I would love this app but there’s so many pop up ADs even after paying for it.
  14. [R4] Welltory 1/5 · US I wish I could give negative stars: You’ll only deal with AI assistants if you subscribe or not. Don’t bother because you’ll go around and around and not resolve a thing. So disappointing!
  15. [R7] Welltory 1/5 · US Can’t cancel: Trying to cancel and it doesn’t let you. Go to help center and it won’t with the conversation to get anywhere.
  16. [R22] Welltory 1/5 · US I want to cancel-no place to do so!: I have wasted an hour trying to find a way to cancel my subscription. This is ridiculous. Put a button somewhere in the app to do this. Why does it take 21 days for you to cancel after receiving an email to cancel.
  17. [R30] Welltory 3/5 · US Egregiously overpriced: Especially given that none of the stress ratings are useful. They’ve never once been reflective of my well-being or performance in a given day. The only thing that I like about this app is the heart rate monitoring and how you can use it for your fitness. It gives you heart rate zones and measures your activity throughout the day, not just during a recorded workout. I can’t
  18. [R36] Welltory 3/5 · US No Way To Contact Developer: I want to cancel my subscription. Doesn’t appear in my Apple subscriptions and it won’t send me a password reset. No link to contact developer anywhere. Subscription page says Premium, but no way to change, cancel or contact. App has shown no personal benefit to me. At all. Please cancel my subscription effective immediately.
  19. [R94] Instant Heart Rate 2/5 · US Not at all what I thought: Mainly got this app for B/P. The app would only take my pulse
  20. [R97] Instant Heart Rate 1/5 · US Finger BP?: Several of this type of health app advertise having the ability to take BP directly from a finger. Blatant false advertising and they all need to take that down. If you want BP you will have to have a BP cuff.
