## What is whentowake?

whentowake tells you the best time to wake up, based on when you are going to sleep.

humans sleep in cycles. waking up in the middle of one leaves you groggy and slow. waking up at the end feels natural. whentowake does the math and gives you three options — short, balanced, and full — so you can choose what fits your schedule.

open the app. see the times. go to sleep.
