When you see the screen below, you can start the measurement by placing your finger on the camera.

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 you place your finger on the camera. Just a gentle touch is fine! If you press too hard, FibriCheck can not take any measurements.

Be sure to check out the video below: 'How to perform a good measurement'

What if this still doesn't work?

  • You have callus formation or a physical problem with your finger?
    You can use any finger to conduct a FibriCheck measurement. The app just needs a spot of skin where there is sufficient blood flow underneath. If using a different finger doesn't work, the ball of your thumb could serve as a possible alternative. 
  • Do you have shaking hands?
    Shaking hands can lead to a problem where the FibriCheck measurement doesn't start. Usually we advise the user to place the hand on a table and position the smartphone on the finger as is illustrated in example 2.

We hope this works! If this is not the case, do not hesitate to contact us via the live chat on our website!
