Pulse Oximeter - Heart Rate and Oxygen Monitor App Reviews


Very inaccurate  ChrissyS12345  1 star

I bought this thinking it would work ok, well that was silly thinking on my part. The o2 readings are very off and could be dangerous to someone that believes them.


Not accurate  Melbw95  1 star

My son was sick and I bought this to check his oxygen level. It said 97%. But once we took him to the hospital his level was really 76% when this said 96% at the same time.


Very poor on SpO2  FidelMontclar  1 star

It is very poor on SpO2 reading, it is not even close to it. The pulse rate measurement it is a bit better.


Not accurate  Ubertoad  1 star

Tested against medical clinic SpO2 devices shows this app to show readings of 99 while calibrated clinic devices gave readings of 92-96. Pulse readings are also inaccurate. Should not be used in a medical or aviation setting.


Not accurate  Txsteffie  1 star

This app is a joke. It is not accurate at all. Don’t waste your money. Now to see if I can get a refund.


Inaccurate  jystabiker  1 star

I should have red the reviews. The pulse portion of this app does not work at all on an iPhone 8plus. The Oximeter portion is off 3-5 percent in comparison to my doctors office Oximeter


Disappointed!  Ally558  1 star

I bought this to measure my blood oxygen levels after being released from hospital with low blood oxygen. The results are way off. Says I have 99% to 100% consistently. I know this is wrong. What a waste of money. I would like a refund!


As good as my dedicated pulse ox  gkasica  5 star

Just installed it on my iPhone X here and even with cold hands-Jackson WI 21F - worked beautifully. Compared to my EMT dedicated pulse ox and was extremely close 3-5bpm and about 3% PO2. Well done.

HORRIBLE  Kath Murph  1 star

I have COPD and need to keep an eye on my oxygen levels. Have an oximeter but thought this would be more convenient since I always have my phone on me. On a good day on oxygen I usually get a testing of 90 - 92. O ALWAYS get a 100% reading with this app. I should have read the reviews before buying. A real ripoff.


This is accurate  MickeytheMike  5 star

At first I was like why is my heart rate low like 55 or 58 I’m pretty sure it’s in the 60’s then I checked on other apps and other equipment like actual Oximeters, and blood pressure machines and it’s in the 58, 57 at rest off course, so it’s pretty accurate not exact but it’s a couple numbers off, like maybe 2 on the beats per minute or 2 on oxygen levels, but I don’t see anything wrong with that, all you people can’t appreciate his/her hard work then just don’t leave anything negative, delete it and leave him/her alone, it’s a fine peace of work.

Excellent oximetry app !


Not improving  hemicolon  2 star

With IOS9.2 the app would work sporadically, usually crashing when pressing start and occasionally almost as soon as the top screen appears. When it stayed, by flicking around in the menus, it would work enough to get some results. Viewing results always crashed it. Force quit, re-starting the device, made no difference. It seems to have kept continuing to pass the data the the Health app. This new version won't even start. I would delete it altogether but want to keep the data recorded so far. If I could get go the results screen, I could export it all then delete and try again. Disappointing that it started so well and went so far downhill.


Something Missing  DeeJayMack  2 star

I got this app to measure ox stats. It does blood pressure too but only one out of two measurements. Then editing - there is none...I want to label whose stats it is but all can do is email it off somewhere or delete it. I really think you have more to work on with this app. I paid $7.99 to expect a good app. Sometimes I think the free ones work better. I know I have donated to you...I hope you use all donations to make the app better.


Absolutely dangerous rip off  Johnnie1948  1 star

My SPO2 is normally around 94-96 when I get it checked at the doctor every month! This stupid app measured 100, 100, 100, 100 etc with one 99. Immediately after a hospital measurement of 94 it showed 100!!! It doesn't sound much but ok is between 95 and 100. 90 to 94 is low. Below 90 - go and see your doctor. Given that 10 percentage points are the measuring point, this app is 60% wrong!!!!!! Very dangerous. The pulse measurement was 66% wrong when compared to a hospital cuff measurement!!! This should be taken off iTunes. Now.


Utter trash  snow_wit  1 star

If I bought a magic-eight ball and asked it to predict my heart rate, it would be more accurate than this app. Absolute garbage. It boggles my mind that people can get away with this stuff. The person who created this app is a thief. Every reading is not only identical, but completely inaccurate. I used it on 3 different people, one was a 3 year old. Every reading was exactly the same.

Ox low


Terrible awful should they should not be able to sell this product. OXGEN level does not work. Always shows 100 no matter how many people you try it in


Works Well  RealRamboRon  3 star

The app does its job and enters in heath app. Can we check how accurate? Way over priced for such a simple app.


Love Tester Anyone?  Moops86  2 star

App is barely able to track a pulse, regardless of finger/position used. Pulse ox is a reassuring 99% except that the whole reason I downloaded the app was due to verified 94% repeat readings at the MD. The app says 99% regardless of time of day or person using. At least a Love Tester or X-ray app tries to entertain you a little.


Great useful app  Sharon2665  5 star

I have used this app for over a year and love it. I work in healthcare and it's useful to monitor folks O2 sats during exercise. I have compared its readings with our professional pulse Oxs many times and it is never more than 1% off either way. I know it says do not use professionally but in the real world many times a regular pulse ox is just not available. In a pinch like that it's great to just be able to grab your phone and trust its readings. Also for home use it's nice not to have to carry or have another instrument. Makes it easy to use for traveling as it's always with you. It's just been a very very useful app that has gotten much use. Coworkers and family always ask to borrow my phone just to use this app.

Works well


Oximeter  tsteinb486  1 star

Does not work on a IPhone 7 plus. The pulse rate is twice the reading from my other oximeters that I have and does not register O2 readings at all. Not worth the money a great idea that needs a lot of work.


Junk  imqueenbee1977  1 star

Doesn't work at all


Do not buy  Alex69073  1 star

You will be wasting your money and time. The result is so far from actual numbers


Not a safe  WalkOffThe3artg  1 star

My fiancé is currently in the hospital with an O2 of 88 but the app says it 100. This is not acceptable and dangerously inaccurate


i like this pulse oxymeter and o2 sat. probe.  Bunjoy  5 star

Highly Recommended App. to all health crazy people.
