Recurring themes

Accuracy mixed
Many users report the app is inaccurate, sometimes giving wildly high or low readings compared to other devices, leading to panic or distrust. However, a significant number of users find it accurate and helpful for monitoring their heart rate.R4R5R6R9
Subscription/Pricing negative
A major pain point is the 'not free' aspect and deceptive billing practices. Users report being charged immediately for annual subscriptions (e.g., $60-$64) despite signing up for a 'free trial' and cancelling within the trial period. The app is advertised as free but quickly pushes for paid subscriptions, with limited functionality in the free version. The cost is considered too high for the features offered.R1R2R5R15
Functionality/Bugs negative
Many users experience issues with the app failing to detect their heart rate, especially on newer iPhone models. Some report the measurement process is too fast in the free version or gets stuck. There are also complaints about losing data after updates and the app not working as expected. The developer's notes mention 'bug fixes' but recent reviews contradict this, with ongoing reports of functionality issues.R12R31R32R33
User Experience/Ads negative
Users are frustrated by mandatory account creation/login, excessive and long ads, and pushy notifications. Some find the interface maddening to navigate or that it prioritizes ads over functionality.R10R13R23R34
Misleading Features negative
The app is criticized for misleading users into believing it can measure blood pressure via the phone camera, when it only allows manual logging.R17R18R41R46

Who it's for

This app might be for users who need a quick, occasional heart rate check and are willing to tolerate ads and potential inaccuracies R6R185. It is NOT for users seeking precise medical-grade readings, those with newer iPhones experiencing functionality issues, or anyone unwilling to deal with aggressive subscription prompts and frequent ads R5R12R21R40.

Evidence note: The sample of recent reviews skews heavily negative (0.592 recent-negative), which contrasts sharply with the lifetime rating of 4.85. This suggests a significant decline in user satisfaction, likely due to recent changes in pricing, functionality, and the introduction of more aggressive monetization tactics. The verdict and score reflect this recent negative trajectory.

No, while the app is advertised as free to download, many users report it is not truly free, with limited use before requiring a subscription and immediate charges even during supposed 'free trials' R1R2R27R49.

No, Instant Heart Rate does not measure blood pressure directly from the phone camera, despite misleading advertising; the blood pressure tab is only for manually logging readings from an external cuff R17R18R41R55.
Why am I being charged for Instant Heart Rate?
Many users report being charged for an annual subscription (around $60-$64) immediately or prematurely, even after signing up for a 'free trial' and attempting to cancel, with some describing it as deceptive billing R2R5R15R21.

  1. [R4] 5/5 · US I think this is pretty accurate: I’ve been feeling weak and dizzy due to my heart rate going up. This helps me know when my heart is going above 100 bpm and when I need to lay down.
  2. [R6] 5/5 · US Its okay I guess: The app is nice, helpful but is it really true? Either way..it has really helped me a lot in the past month and days too and pretty good anyway over all it seems pretty accurate oh and by the way can you add a iPad version please and thank you?
  3. [R9] 5/5 · US Most accurate!: I downloaded three apps and one said my bpm was 53, one said 72, and this one said 117. I checked my bpm manually and I got 116.
  4. [R28] 5/5 · US Accurate: It actually reads right
  5. [R73] 3/5 · US Works well, won’t read low HR: App is easy to use and works well. Only problem is, since the new update, it won’t work for a heart rate less than 40 bpm. Sometimes my heart rate can be 38-39. If this is true (per my watch), the app glitches and won’t register it. It just doesn’t work!!! This didn’t used to be true, only since a recent update. Very annoying!!
  6. [R118] 5/5 · US Simple quick easy: Helping me keep an eye on my HR which is Wacky at times… simple, quick and easy…to operate and record and track …
  7. [R140] 5/5 · US So easy to use: So easy to check at anytime. Great ap
  8. [R185] 5/5 · US So quick: I love using this app when I have done something strenuous to see what my heart rate is. Also, it’s interesting to note when I first wake up in the morning, what it is And how it varies throughout the day. It is very quick takes only a couple of seconds And is so easy to use.
  9. [R52] 5/5 · US love this app detected heart palpitations and bracyacardia: i started using this app when i kept feeling random strong beats and it detected heart palpitations so i went to the doctor and I’m now getting a monitor in the next two weeks it’s very accurate and consistent Side note: it is not an ekg it shows the rhythm of your heart
  10. [R69] 5/5 · US Surprisingly accurate: This app is a quick and easy way to find your pulse and automatically log past results. The free version also generates a plethysmogram which detects AFib and other arrhythmias.
  11. [R159] 5/5 · US This app saved my life potentially!: I found out I Could have POTS from this test, not Hyperthyroid which means I could finally not feel out of energy to the point where I cannot get up and light activity feels like running on the treadmill. I found out cause my heart jumps from 75 to 120 then stabilizes to 100 which is NOT normal. Gonna get it checked out but may have solvent the mystery could no
  12. [R20] 4/5 · US Great!: I use this when my workouts end.
  13. [R201] 5/5 · US it helps me: it helps me know that my heart is OK because I have a heart condition so I gotta make sure my heart‘s OK so thank you whoever made this app
  14. [R5] 1/5 · US Be Aware this App isn’t Accurate, Don’t Waste Your Money!: This app is fine if you’re using the free version. It’s not accurate, which is why purchasing any paid subscription is not worth it. Save your money and find a different app that can actually detect your heart rate. I accidentally paid for a year long subscription for $60 when I thought I’d try out the paid version for a free 3 day trial,
  15. [R14] 1/5 · US INACCURATE!: Used to be accurate, not accurate anymore. I thought something was seriously wrong with me.
  16. [R16] 1/5 · US Not accurate: I was in the ER and tested this. It was 20 points higher than the one in the ER. Made me believe I was in more danger than I actually was along with my other symptoms.
  17. [R19] 1/5 · US Pathetic: This monitor is honestly pathetic. I compared it with my 68 year old dads actual heart rate blood pressure monitor and it was so different compared to the inaccurate readings that this thing gives… this thing made me feel like I was dying with its BPM feedback. What a scam. I hope this thing gets shut down because I honestly can’t imagine how many people actually believe it’s lies
  18. [R2] 1/5 · US Not happy: Cancelled membership but was still charged 64 for something I never even used
  19. [R15] 1/5 · US They try to charge you fast: They tried to take 60 dollars before the free trial was even over! Dont use this.
  20. [R21] 1/5 · US Not happy: It does tell you what your heart rate is. It gives you a 3 day free trial. However, if you decide you do not want the subscription, there is no way to cancel it. You will still be charged and apple will not refund. They stole $64.36 from me. When I finally got a response from someone from customer service from this app, they told me they can’t issue any refunds, only Apple can. And I do
  21. [R12] 1/5 · US Terrible do NOT get.: my friend wanted me to get this app to reacted to different names when she mentioned them, and it DOESN’T work at all. It keeps telling me to gently place my index finger over my camera lens, but I do MULTIPLE times and it doesn’t work! I also have a pretty new IPhone so it should work.
  22. [R31] 2/5 · US Junk: It rarely works for pulse reading. By the time it can finally detect a pulse, it’s an at rest beat, worthless.
  23. [R33] 1/5 · US Waste of time avoid it: Was trying for good 20 minutes just nothing
  24. [R40] 1/5 · US No longer works. Nonexistent customer service.: Not only does the app no longer work properly. Forget it if you have a newer model phone. It is finicky at best if your finger tip is not borderline hot and pressed against the camera so hard you feel like you’re punching a hole through the back of your phone. There is absolutely no customer support. Aside from them, seemingly responding to negativ
  25. [R10] 2/5 · US Pushy: Kind of pushy that another app needs you to make an account to use it(presumably to sell your info)
  26. [R13] 1/5 · US Requires login/dara risk: Requires login, cannot be trusted with private health data
  27. [R38] 1/5 · US Can't do anything without signing up.: There's no reason why I need to sign up just to get a heart rate reading.
  28. [R95] 3/5 · US Deleted: I used to live this app but New version won’t let you use unless you log on with your email and create an account. Immediately deleted ! There are alternatives in Apple Store that won’t require account creation
  29. [R45] 1/5 · US THE WORST APP I EVER DOWBLOADED IT IS COMPLETELY INNACURATE IM ABOUT TO HAVE A HEART ATTACK: THE WORST APP I EVER DOWBLOADED IT IS COMPLETELY INNACURATE IM ABOUT TO HAVE A HEART ATTACK THIS APP PRIORITIZES ADS AND DOESNT TELL U YOUR DAMN PULSE!!! DO NOT DOWNLOAD THIS APP IS THE DEVIL
  30. [R48] 1/5 · US Getting past the ads will raise your blood pressure.: It tries to force you to install other apps. There is no free version as claimed. The more I tried to get it function, the higher my blood pressure and pulse.
  31. [R49] 1/5 · US Nothing but pressure to make you pay: Their version of “free heart rate monitor” makes you wait for a measure for 30 seconds then for seconds more, then 20 more. Right until you heart rate is down after the workout. Presumably direction you to pay for a premium. Shame on you, if you wanna charge people, do it openly, put it beyond the paywall. Soft scammers.
  32. [R223] 3/5 · US Acceptable Heart Log: Tracks heart rate okay. Wacky reads sometimes. Ads have become pretty aggressive and obnoxious.
  33. [R11] 1/5 · US Horrible customer service: I decided to delete and they are obnoxious and offensive making it difficult to exit.
  34. [R37] 1/5 · US Paid for Premium version but doesn’t work: I upgraded to the Premium version but it never worked. Kept telling me I was subscribed but the interface was stuck at the free version. Their customer support was clueless and could not solve the issue going into 6 months now (they apparently have no software engineers). They told me to get a refund from Apple but I can only access the last 2 months of s
  35. [R112] 5/5 · US Only 7 seconds of measurement: The free version of this app has changed from unlimited seconds per measurement to only 7 seconds, making it pretty useless. By the time I get the phone near my heart and my finger and finger pressure placed accurately, I end up with only 1-2 seconds of measurement - too short for the reading to be accurate. They made a good app bad.
  36. [R117] 5/5 · US heart rate monitors too fast: HR monitor finger scanning process is too fast and only lets you check your heart rate over a 5 seconds period. that's not enough time to watch heart rate stabilize over the scanning period. revert back to old scan duration.
  37. [R283] 3/5 · GB Not a free App!: Very limited use
  38. [R17] 2/5 · US Not at all what I thought: Mainly got this app for B/P. The app would only take my pulse
  39. [R18] 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.
  40. [R41] 2/5 · US Description is misleading: The photos make it seem like this app uses pulse rate data to calculate blood pressures, however the bp tab is just a log for the user to manually enter blood pressure reading from a at home cuff or doctors check ups. I have followed every tip for good readings but all the heart data just says it’s not getting a good readings. Not worth 9.99 a month
  41. [R46] 1/5 · US Classic Bait and Switch!: Lousy app. If you say you are monitoring BP, and you are free, then the least you have to do is allow me to measure my BP without having to pay. I don’t care for my heart rate - that’s already taken care of by my watch. Classic bait and switch!
  42. [R88] 3/5 · US Could be more useful: The info it collects is helpful, except it only retains part of the data collected from each test. It would be far more useful for me if the whole chart was stored and shareable the same way it’s collected. Also, if I use it 3X in a row, sitting in the same chair, same position, I get 3 very different measurements. Not sure why. So it’s not very useful for me now. If I knew
  43. [R98] 4/5 · US Used to work: Doesn’t store any information of previous readings anymore
  44. [R113] 3/5 · US lost readings with update: App was working great for me. Recently did the update and lost almost all my BP readings. Lost the entire month of July and most of August.
  45. [R182] 5/5 · US Works well for free but keeps asking me to pay - so annoying: Works well. Wish it transferred data to apple health. But it only takes heart rate so for me Not worth $6.99 monthly or $39 annually. I would consider buying for one time fee of $39, but there are other options that do much more.
  46. [R569] 3/5 · CA Long time user. Too expensive.: When the app first came out I bought premium right away. It was a one time purchase, done. Later on they pulled my premium and then flipped on a yearly sub option priced at a medical equipment rate.. There was also no way I could find on how to restore my purchases. I have a lot of yearly pay apps but they offer evolving streams of data or have off phone servi
  47. [R589] 3/5 · CA Ads absolutely everywhere…: The app works just fine at checking your pulse, but there are way too many advertisements throughout the whole app.. I also believe the cost of the subscription is too high for only a few extra features.
  48. [R7] 1/5 · US Bad privacy: I bet nobody actually reads the privacy policy. Read it.
  49. [R23] 1/5 · US .: Install app. Open app. “Enable notifications” uninstall app. Leave me alone.
  50. [R43] 1/5 · US Mandatory notifications: I don’t like notifications. They are mandatory with this app.
  51. [R1] 1/5 · US Not Free: Not Free
  52. [R32] 1/5 · US Malfunctioning: Paid, then it froze a few times, could not take hrv, although i was completely still, was asking me to select a state to showe my results, although i had selected a state - i deleted it.
  53. [R34] 3/5 · US Maddening to sign in: There was no way to close the keyboard so I could reach the "sign up" or "login" options at the top. I had to force quit the app and start over multiple times to get signed in. I already had an account from a long time ago, so I used the forgotten password feature. In the email, there was a button to open the app, but it took me to the web instead. It took forever to take
  54. [R27] 1/5 · US Free: You said it was free-well you lied
  55. [R55] 1/5 · US Doesn’t test blood pressure: This app acts as if it will test your blood pressure with the camera on the phone, but it does not.
  56. [R47] 1/5 · US Doesn’t work: It could not detect my pulse. I put my finger on the camera and it would get a beat or two and lose the pulse instantly. I have a brand new iPhone 16.
  57. [R83] 5/5 · US Not working with IPhone upgrade: Will not detect heart rate on new iPhone 17pro
  58. [R92] 4/5 · US Great app but needs update: Not compatible with the new IPhone 17 Promax. Please fix this!
  59. [R181] 5/5 · US iPhone 16: The app worked great on my old iPhone 11. But I cannot get it to work on my iPhone 16. Any help would be appreciated.
