Calculate optimal bedtime based on your natural sleep cycles and track sleep.

Good day starts with good morning! Go to bed at the right time and wake up in between your natural 90-minute sleep cycles to feel rested and refreshed. A good night's sleep consists of 5-6 complete sleep cycles.

◦ Calculate your best time to go to sleep

◦ Calculate the best time to wake up

It takes an average human about 15 minutes to fall asleep. If you wake up at one of the calculated times, you'll rise in between 90-minute sleep cycles.

Sleep Calculator helps you decide when to go to bed so that you can wake at a specific time ensuring a good night’s rest, or what time you should wake up if you want to go to bed right now.

If you want to determine your real sleep cycles - our Sleep Tracker functionality allows you to track and analyze your sleep and, if done correctly, will show you your sleep progress – when you were in light, deep or REM (dream) sleep phase and the breakdown of your sleep cycles. Snoring/noise detection can be enabled as well.

Our brand new Smart Alarm will wake you up easy in the lightest sleep phase, making sure you wake up easy and rested.

Bedtime notifications can also be set up so that you do not miss a proper time to go to sleep.
