Your Withings Activité / Pop lets you track your sleep without requiring any action on your part. All you have to do is wear your Withings Activité / Pop to sleep: it will do the rest on its own.
If you do not want to track your sleep, remove your Withings Activité / Pop before going to sleep.
Retrieving your Sleep Data
You can retrieve the sleep data collected by your Withings Activité / Pop in your Timeline or on your Dashboard in the Withings Withings App.
White: time spent out of bed - Grey: time spent awake (in bed) - Medium blue: duration of light sleep - Dark blue: duration of deep sleep
The Withings App keeps your entire history, allowing you to easily track how your sleep data evolves over time.
