Sleep well.

We’re proud to unveil a total refresh of Sleep Time Calculator, a sweet and simple app with one goal in mind: to help you sleep better. Whether you’re deciding when to go to bed or when to wake up, Sleep Time Calculator will calculate the ideal time to do it. How? It all comes down to sleep cycles.

A complete cycle is formed from alternating REM and non-REM (‘deep’) sleep stages. Your body will generally come awake after 4 to 6 of these cycles over the course of the night. The ideal time to wake up is at the end of a cycle rather than in the middle, and that’s exactly what Sleep Time Calculator recommends you do.

Sleep is one of the most important things. Why not sleep better? Sleep Time Calculator can help.

Grab it on the iOS app store right here.
