Thank you for trying the APP. Please follow the guide for measurement. Keep your finger over the camera and don't move it when measuring, and the amplitude of the waveform will not drift greatly during normal measurement, refer to the screenshot of App.
Heart rate
Inaccurate
Response from developer
Thank you for choosing this app. ★ Keep the correct measurement method, the result is accurate. ★ A large number of test cases and analysis conclusions have great reference value. It follows the relevant standards. Users can measure their heart rate for free before purchasing premium features, and you can refund if you don’t need it. Thanks!
Great heart rate recording app
Response from developer
Thanks for your feedback and encouragement, we did a lot of testing with the professional devices. In addition, it is normal for the heart rate value to have some fluctuations, rather than being constant at a value.
