5 stars: Does what it says on the tin. Takes IR SpO2 and pulse rate over several seconds and gives an average. Considering sats seem to have disappeared from most apps this is great. Particularly with the trend graph over several uses.
5 stars: Seems pretty accurate on a Galaxy S8. Easy to obtain readings on both pulse and oxygen saturation. Also displays a real time visual EKG waveform. Provides a good piece of mind during these concerning times.
5 stars: Great app. The heart rate is accurate - I get the same numbers from my bp equipment. Eaay to use. The historical chart is exportable and my dr likes the data.
4 stars: Excellent app. Works like a breeze. Free version only measure 3 times a day. Increase it at least to 5 times daily.
5 stars: So far so good glad I can monitor my oxygen I'm at a 6000 elevation area originally from a 650 area...hydrating is a must
5 stars: Very useful application, easy to use and readings are perfect. Overall excellent product
4 stars: The heart rate is true but spo2 level seems incorrect . It is always 99% . My device has a built in spo2 sensor
4 stars: Ok to have it in yr phone. Not sure about reading. Has to be calibrated with equipment. Overall good
5 stars: Very good simple and gives 98 percent accurate results as compared to hospital large monitor based machines and finger transducer
4 stars: It works fine but sometimes the results show some deviation
5 stars: I am a Consultant Anesthesiologist. Do...
