How your day goes depends a lot on how good you sleep. A good sleep makes you healthy, intelligent and alert.

Human sleep consists of a series of cycles, each of which lasts around 90 minutes. Waking up during a sleep cycle leaves you feeling tired and groggy even if you have slept for long enough. But waking up in between cycles lets you wake up feeling refreshed and alert.

SleepTime calculator helps you find the best times to sleep or wake up. You can then setup an alarm to wake at the right time.The app is perfect for those with a tight schedule, students, and pretty much anyone who wants to stay in top shape! Skeptical? Try it!
