Sleep calculator for ideal bedtimes, wake-up times & sleep cycles
Sleep Calculator helps you find the best time to go to bed or wake up by using natural sleep cycles. It’s a simple sleep planner designed to support healthier sleep routines and more refreshing mornings.
Instead of waking up in the middle of a sleep cycle, the app calculates ideal bedtimes and wake-up times based on complete sleep cycles. Each cycle lasts about 90 minutes, and the app also includes an estimated 14-minute fall-asleep time to provide more realistic results.
