Waking up at the right time feels like waking up naturally without an alarm.
With REM, you can wake up feeling refreshed and go to sleep listening to soothing sounds such as Thunderstorm, Stream, Summer Night, Forest, White Noise, and much more.
REM Sleep Calculator uses the average sleep cycle of 90 minutes along with the length of time it takes for you to fall asleep to calculate the moments of time you will be in your lightest sleep.
