Tap anywhere on the Night Card to discover your hypnogram.


The hypnogram
The hypnogram is a diagram obtained by the continuous recording of the electroencephalogram during sleep. This makes it possible to identify sleep cycles during the night. This information is supplemented by data on your position, heart rate and respiratory rate. Below, you can see the default view of your hypnogram. Here your whole night is compressed for better visibility.


  • Tap the sleep phase you're interested in to see when it's represented in your night and some data figures.

  • Scroll the slider to see the details of your night, phase-to-phase, and observe variations in position, heart rate, and breathing rate.
