The Quick Look feature allows you to light up the screen of your Pulse HR. To do so, simply raise your wrist and turn it towards you, or press the side button. Tap the screen or press the button to scroll through data: date and time, heart rate, step, distance, calories burned, and alarm.
The Quick Look feature can be activated or deactivated in the quick settings of the Withings App. To do so, go to Devices > Pulse HR > Activate the Quick Look.
