In plain words

A bedtime calculator built with React that helps users determine when to go to sleep based on sleep cycle science. The tool is designed for anyone looking to optimize their sleep schedule, though it was created by a teenager. It calculates ideal bedtimes by accounting for the time needed to fall asleep and the duration of sleep cycles, allowing users to wake up at more natural points in their sleep pattern.
