Photoplethysmography is a tried-and-true practice, every app is designed in different way using different algorithms because of which the results of each app is not same as other. However, these results are near to one another. Researchers conducted a research and compared four apps to clinical gold standard measurements (ECG and fingertip pulse oximetry), they concluded that the readings of heart beat generated by apps show more than 20 beats a minute in over 20% of measurements.
The researchers also concluded that the app associated phone’s built-in camera works better when recorded placing a fingertip over the camera than face. Here, we have come up with some popular accurate heart monitor apps, we recommend using these heart rate monitor apps for accuracy.
