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.

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 brand new 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.

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