To check your heart rhythm, tap on 'Measure' / 'the red heart'. Place your finger on the camera to start the measurement. The measurement will take 60 seconds.
Note: It's not required to place the finger on the flash as this can become hot!
Some tips to performe a good measurement:
Tip 1: Sit down quietly
Sit quietly, rest your arms on a flat surface during the measurement, stay still and do not talk.
Tip 2: Remove your case
If you have a protective case around your smartphone please remove it, this may result in poor contact between the finger and the lens of the camera. If you remove your case, there will be better contact between your finger and the camera. This will lead to a better measurement.
Tip 3: Cover the lens of the camera, not the flash!
There is no need to place your finger on the flash. This can become hot in some cases. Do not apply too much pressure when placing your finger on the camera. Just a gentle touch is fine! If you press too hard, FibriCheck will not be able to perform a correct measurement.
