"Sleep Cycle Calculator Lite" is the free version of "Sleep Cycle Calculator", an application that calculates the best time for you to sleep by counting your sleep cycles.By counting in sleep cycles and incorporating how long it takes for you to fall asleep, this application determines when you should sleep and when you should wake up based on the average human sleep cycle. Humans naturally have multiple sleep cycles every night and it’s during these sleep cycles that we are truly resting.If we wake up in the middle of one of these cycles, we will feel groggy and much more tired than normal because we have interrupted an important process. However, if we we wake up in between two sleep cycles, we will feel far more refreshed even if we’ve had less sleep. This is because humans naturally wake up in between sleep cycles, provided we aren’t disturbed by things like alarm clocks and other loud noises.If you found the free version of "Sleep Cycle Calculator" useful, we hope you’ll take the step and upgrade to the Pro version to show your support.
