How my ZeRound assesses the quality of my sleep?

You can use your ZeRound to track and analyze not only the duration of your sleep but also its quality.

Our tri-axial accelerometer can detect if you're in a light sleep, deep sleep or awakening as the movements made during sleep.

  • Light sleep assumes that you are not asleep, but we're not constantly in motion.
  • Deep sleep means that you are completely asleep and are immobile.

The quality of your sleep is evaluated based on the duration of the three phases during sleep compared to the initial target.

Information: We remind our users that ZeRound and all our watches with a tracker activities are intended for daily use and indicative.
