This app tracks your sleep cycles to help you wake up at the optimal time. It calculates when you should go to bed or wake up to ensure you're not disturbed mid-cycle, leading to a more refreshed feeling.
The app considers that sleep occurs in cycles of approximately 1.5 hours. By identifying the end of a sleep cycle, it suggests a wake-up time that will leave you feeling alert and not groggy.
