Android App Analysis and Review: Pulse Oximeter - Beat & Oxygen, Developed by PVDApps. Listed in Health & fitness Category. Current Version Is 1.4.0, Updated On 12/10/2025 . According to users reviews on Google Play: Pulse Oximeter - Beat & Oxygen. Achieved Over 777 thousand Installs. Pulse Oximeter - Beat & Oxygen Currently Has 10 thousand Reviews, Average Rating 3.9 Stars
Check your oxygen saturation and heart rate anytime, anywhere with the Pulse Oximeter app and your built-in sensor - at your home or office - when you wake up, relax, before and after exercise.This app only works with built-in sensors on these Samsung devices: Galaxy Note4/Edge/5/7/8/9 and Galaxy S6/7/8/9/10 include plus variant.
App used an advanced algorithm to calculate oxygen saturation from the sensor's raw infrared and red signal output, similar to how a dedicated pulse oximeter works.
Instant and excellent for monitoring your fitness.
FEATURES:
- Measure range for SPO2: 70%-100%, for heart rate: 30-190 BPM.
- Fast or continuous measurement.
- Save results with tags for access later.
- Real-time pulse graph (PPG - photoplethysmogram).
- Reminder: Automatic reminds you to measure your oxygen saturation and heartbeat daily.
- Share your heart rate and SPO2 screenshot on social media.
- Export history to CSV or PDF file format; PDF format includes PPG graph. (Paid feature).
- Back up, restore and transfer your data. (Paid feature)
Please note that the free version allows only 3-5 measurements daily with ads display; you can purchase IN-APP to get unlimited measurement, additional features, and no ads.
VERIFY AND CALIBRATION:
- "Hold the breath" will reduce your blood oxygen level; for most people, it's safe to hold your breath for a minute.
We tested with the "hold the breath" method for 30 seconds, the oxygen saturation will go down to about 94%, but it depends on your condition.
Open app Settings, change the "Auto-stop after" option to 2 minutes, and you can start the testing.
You can see our test video: https://youtu.be/fVtCBf-8DfI and https://youtu.be/M9q8iCyw9uI.
- Calibrate the app: choose the option in Settings -> Calibration -> "Alternative" or another variant; if you see the result higher/lower than expected, you can also compare it to other devices at the same time (one on the left hand, one on the right hand, each finger with one device).
You can try the "hold the breath" method to calibrate the app.
- Recommend calibration:
'Default': S6, S9, S9+, S10, S10+, Note5, Note9
'Alternative': S8, S8+, Note7/FE, Note8
'Alternative 2': Note4, S7, S7 Edge

It's good and fairly accurate as it turns out. The only issue I have is that the SPO2 and BPM markers don't align on the graph, such as when you view week or month graph. Say I do a reading where both measurements are taken, like normal, they will be aligned to different times on the graph, even though they actually say the same time when tapping on them. The first graph on the History tab that shows the last 7 or so readings is aligned however.

If your device supports it (Samsung Note 4 through 9 and Galaxy S6 through S10 according to the developer), this app is an improvement over Samsung Health's pulse ox module - it provides a history, which can be exported (a premium feature, but not expensive). Plus it's quick to use and can be calibrated to some extent (though I haven't done this myself).

If you want a Pulse Oximeter for real actual use (not just somewhere to record SPO² readings) then this is the only app that I would recommend. In fact, this seems to be the only app out there which can do this. Using end of fingertip (rather than whole fingerprint surface) gives same reading as my smartwatch - and is worth the $2.99 for lifetime access, especially if you have not got access to a smartwatch, or want reassurance from a second measuring device.

Very difficult to get reading in free app but it did show an spO2% saturation quickly without reading pulse. Decided to try premium. Couldn't get a reading. Never showed O2% saturation but did exhibit good pulse waveform without giving heart rate. The problem isn't my phone (Note 9). Serious software defects are the problem. Good useful concept; poor execution.

Works but not too sure about the calibration. Bigger problem... The free version only allows 3 readings per day?! Wouldn't it make more sense for the pay version to include things like history but allow unlimited readings? Not going to uninstall it but absolutely would not consider paying for it due to this.

Unfortunately I got a 3 day opportunity to use app dozens of times and compare to a hospitals oximeter. Every time it reported one degree less than the hospital unit which was probably a rounding difference. Hospital staff was pretty amazed for such an accurate, cheap and reliable app. Really happy I bought it and would again if necessary.

Very nice app. Great user interface: easy to use, good graphics, good data logging. I like how you can adjust the measurement time. It works with either the Samsung built-in heart rate sensor or the flash/camera. Both work well, but the Samsung sensor is better. Accuracy is great: I've been testing both HR and oxygen sat against a fingertip SpO2 gadget. Of course you have to sit still (like with any of these apps).

Been really worried about my sp02 levels lately and when my 3 free readings for the day were not so great, I panicked into purchasing the premium version so I could do more readings... since doing that though the app has been working worse then it ever did before purchasing the premium and I'm beyond disappointed and don't think I would recommend this app, especially paying for it - to anyone honestly. If it's that important to you, go by the real thing that can be actually trusted.
