Naptime: Smart Nap Alarm for Android

Naptime: Smart Nap Alarm is an educational application designed to enhance napping efficiency by accurately measuring sleep onset. Utilizing the phone's accelerometer, the app begins its countdown only after the user has fallen asleep, effectively ensuring that a 20-minute nap corresponds to 20 minutes of actual rest. Customizable nap lengths, anonymous movement synchronization for detection tuning, and the ability to run in the background make it suitable for students, office workers, and habitual nappers seeking quick rejuvenation throughout the day.

The application incorporates a feature called Smart Sleep Detection, which tracks the transition from wakefulness to sleep using accelerometer data. This method addresses the common issue of timer anxiety, allowing users to enjoy short restorative naps without the worry of losing valuable sleep time while trying to drift off. With a lightweight installation under 20MB and compatibility with devices running Android 7.0 or higher, Naptime seamlessly integrates into daily routines, providing a practical solution for users looking for efficient nap management.
