Latest update · v3.4.2

What the developer says changed (the verdict above weighs this against what reviewers report):

Optimizing heart rate measurement technology

Recurring themes

Misleading Pricing negative
Many users downloaded the app believing it was free, only to find out they needed to pay a weekly or monthly subscription, often immediately after providing personal information. Prices cited range from $6.99/month to $9.99/week or $40/month, leading to frustration and feelings of being scammed.R3R4R5R9
Inaccurate/Missing Measurements negative
A significant number of reviews state the app does not accurately measure blood pressure or blood sugar, despite advertising claims. For blood pressure, users often find it requires manual input or gives consistent, unrealistic readings. For blood sugar, it often only allows logging from an external device or taking a picture of a glucose meter. Heart rate accuracy is also questioned by some.R1R6R11R13
Subscription Cancellation Issues negative
Several users reported difficulty finding how to cancel their free trials or subscriptions, with some claiming they were still charged after attempting to cancel.R3R7R8R14
Heart Rate Monitoring positive
Despite issues with other features, many users appreciate the app for its heart rate monitoring capabilities, finding it easy to use and helpful for daily tracking. Some even express gratitude for a free option to monitor heart health, though this contradicts the widespread reports of paid subscriptions.R10R12R20R48
Excessive Ads negative
A notable number of users complain about the high frequency and intrusiveness of ads, sometimes appearing multiple times before any functionality can be accessed, making the app annoying and difficult to use.R33R39R65R168

Who it's for

This app might be for individuals primarily interested in a basic, convenient heart rate monitor on their phone, provided they are aware of potential subscription costs and accuracy limitations R48. It is NOT for users seeking accurate blood pressure or blood sugar measurements from their phone, or those looking for a genuinely free health monitoring solution R1R6R22.

Evidence note: The recent reviews skew heavily negative, particularly regarding the app's pricing model and the accuracy/availability of advertised features like blood pressure and blood sugar measurement. While there are positive reviews, they often focus on heart rate monitoring and sometimes contradict the widespread reports of paid subscriptions by stating the app is free. The developer's release notes mention "Optimizing heart rate measurement technology," which aligns with the positive feedback on heart rate, but does not address the major concerns about pricing or other inaccurate measurements.

  8. [R79] 5/5 · US Health: I love the convenience of it because I have to monitor my blood pressure because of pain issues and medication so my doctor can adjust to it so basically I’m doing his job or her job whatever but I do love the app
  9. [R89] 5/5 · US One Stop App: Yes! No more lugging around monitors, extra watches that measure BP and then trying to merge data for the doctor!
  10. [R131] 5/5 · US Heart monitor: This so cool one place, for all my Important stuff.
  11. [R147] 5/5 · US Heart checking: Love this gadget best thing I have ever seen. I don’t have to worry about pumping my arm and carrying things with me just my phone. Thank you very much I know I’m going to enjoy it. Doctor wants me to check my blood pressure every day because I have high blood pressure so now I can do it. Thank you so much.
  12. [R3] 1/5 · US Waste of time: I downloaded the app and it was not free as it claimed in the beginning. So I paid about $45 for nothing. It’s definitely inaccurate and every time I open it, the app doesn’t remember me.. By the way the blood pressure app has the same problem. Waste of money. Please tell me how I can request a refund.
  13. [R4] 1/5 · US another one: another lie to get you to download, seen a ad says completely free, not completely free to download but completely free period!! why can’t people that produce these apps just be truthful? it’s not hard to do and is the only right way to be!! Deleting app don’t want to pay for something like this and probably don’t don’t work? there’s a reason hospitals use precision tools for checking
  14. [R5] 1/5 · US IS NOT FREE AT ALL: On the advertising it says “and it is free”. Yeah free to download and fill out all the questions but not FREE to use. You should be putting that information in your advertising so people don’t waste their time. Or clarify that to use it is 9.99 a WEEK!
  15. [R9] 1/5 · US Be Careful: I thought this was supposed to be free. Next thing I knew I was immediately charged $9.99. I’d like my money refunded. It happened so quickly it said to click here and next thing I knew my credit card was charged.
  16. [R1] 1/5 · US Misleading information: Not for blood sugar and blood pressure
  17. [R6] 1/5 · US Incorrect blood sugar levels: Tested my blood sugar at 120, the app says 85. Useless
  18. [R11] 3/5 · US heart rate blood pressure reading.: very disappointed. lost 39.00 and stuck for a year. stupid me bought for year by mistake. not convinced it actually reads true readings. save your money
  19. [R13] 1/5 · US THIS APP CANT DO WHAT IT CLAIMS. THEY ARE LYING TO YOU IN HOPES THAT YOU’LL LIKE THEIR APP AND USE: There have been a couple apps like this that mislead you into thinking they can read blood glucose. At best they can read from other devices or store the info you put into their app. I will never buy an app from developers who mislead me like this because they have no integrity and will do it aga
  20. [R7] 1/5 · US Please cancel this app: I don’t want this any longer remove it
  21. [R8] 1/5 · US do not get: cannot cancel
  22. [R14] 1/5 · US Don’t do it: It is a trap and I haven’t found a way to cancel it either!!!!
  23. [R33] 1/5 · US ADs prevent real time monitoring: Terrible app if you have POTS, anemia, etc and are in need real-time monitoring. When you open the app, first you have to wait for TWO AD cycles while trying not to pass out. By time the ADs can be closed, your heart rate had already shifted. Absolutely awful to prevent monitoring until after ADs cycle. Carry your oximeter, this is not a suitable replacement.
  24. [R39] 1/5 · US More annoying than helpful: Starts with 7 ads before you can do anything. The controls are unintuitive, it is so inaccurate it is useless, and takes so long to get to a position to check your pulse it is more dangerous to your health than helpful. Plus since getting to the place to take your pulse is so frustrating it raises your pulse… As a former medical professional I’d guess this app kills
  25. [R65] 1/5 · US Too many ads!!: Just downloaded the app to test and see if it works for me. But my god way too many ads. Makes it very annoying and hard to like. I know it’s free to download but make it enjoyable so that we can enjoy it and maybe subscribe. I might just delete it!
  26. [R168] 4/5 · US Enjoy the App: I like this program but has too many advertisements
  27. [R32] 1/5 · US Bait and switch: Have to pay a subscription to get more than a heart rate, which is also inaccurate according to my Apple Watch.
  28. [R34] 1/5 · US Clickbait: Impossible to use without a paid plan. Also, I compared it to my gauges and it was way off.
  29. [R137] 3/5 · US New Customer: This survey jumped the gun. I just started the app 5 minutes before survey and I’m locked in to answering good or bad before proceeding. Maybe you should take a look at giving that question more time to answer properly.
  30. [R215] 3/5 · US Ok: But I can’t tell if it took my blood pressure or did I have to put it in myself! That’s kind of confusing to me! And why they cost it already in the cameras what do have to pay for! I could see if it did something amazing but there are free things that do this! So not impressed
  31. [R17] 1/5 · US False Advertisement: Not completely free as advertised it cost $9.99/week
  32. [R21] 1/5 · US App is not free: App is not free. It’s $40 a month.
  33. [R22] 1/5 · US WARNING: misleading app claims: as someone researching health monitoring tools I am deeply concerned the apps claiming to measure blood sugar and blood pressure using only a smart phone, or even allowed to exist. A phone camera can reasonably estimate heart rate because it detect changes in blood flow using the light called photoplethysmography. that is not the same as checking blood sugar or blo
