Wake Up Feeling Refreshed
Tired of being tired? Sleep Calculator helps you find the ideal time to go to bed or wake up!
Our brains move through natural 90-minute sleep cycles. Sleep Calculator helps you wake up between these cycles — so you start your day feeling refreshed and energized!

• Calculate the optimal bedtime for your desired wake-up time
• Find the best wake-up times if you’re heading to bed now
• Simple and intuitive interface

HOW IT WORKS:
Sleep Calculator - Sleep Cycle assumes it takes about 15 minutes to fall asleep, and calculates your ideal sleep or wake times based on complete 90-minute sleep cycles. Choose the time that fits your schedule best — and avoid waking up mid-cycle.
Whether you’re an early bird or a night owl, Sleep Calculator helps you wake up at the right time and reduce morning grogginess.
