How do I take my resting heart rate using the doppel app?

doppel works best when its rhythms are based on your physiology. All pre-set rhythms will be derived from your resting heart rate.

Before you take your resting heart rate, make sure that you’re relaxed, and that you’ve been sitting down for at least five minutes. You can also try first thing in the morning.

Guidelines

Make sure you take your resting heart rate in a good light.

Place your finger over the camera lens on your phone. Press ‘Start’ to begin measuring your heart rate.

Please remove any attached phone case, if you are struggling to cover the camera with your finger.

I already know my heart rate

If you already know your resting heart rate you can enter it directly.
