Waking up during the right sleep stage is essential to feeling refreshed and energized. Pillow’s Smart Wake-Up feature is designed to help with this.
Instead of waiting until the exact alarm time you set, Pillow can wake you up a few minutes earlier if it detects that you are in a lighter sleep stage, or even in an awake period. By doing so, Pillow helps you wake up more smoothly, rather than pulling you out of deep sleep, which can leave you feeling groggy.
This adaptive approach is meant to improve how rested and revitalized you feel in the morning.
