About this app

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

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).

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).

So far so good. Haven't had the chance to compare it to an actual meter. The only other issue would be, I have an advanced case of A-fib and it seems like it can't pick up a signal to get started. Can be difficult to pickup pulse ans pulse ox at times. I do have Afib the could be the issue but doesn't pose an issue in any other apps. Maybe one of camera lenses has a scratch on it.

Thanks for your feedback. You can check our test video: https://youtu.be/M9q8iCyw9uI

What's new

- You can export History to PDF file format with PPG waveform (premium only). Share the heart rate/SPO2 measurement on social media as an image.
- Bug fixes & Performance improvements.
- Calibrate the SPO2 result: choose option the Settings -> "Calibration" -> "Alternative" or other variant if you see the result higher/lower than expected.
For Note4 when the red led does not light up, try to reboot/reset the phone, the last option is downgrade to Android 5
