Wake gently with your natural rhythm
When do you need to rise?
Sleep comes in cycles. Each one lasts about 90 minutes and moves through light sleep, deep sleep, and REM — the stage where you dream.
Timing is everything. Waking at the end of a cycle (rather than the middle) means you surface naturally, feeling clear-headed instead of foggy.
We do the math. Sleepwell counts backward (or forward) in 90-minute intervals, adding 15 minutes for the time it takes to fall asleep, so you can plan the perfect night.
