Naptime: Premium Nap Timer

Naptime is a smart nap timer, power nap alarm, and sleep tracker without wearables. Unlike a normal countdown timer, it detects when you fall asleep and starts your nap timer then. Set a 20-minute nap, but spend 15 minutes falling asleep. Frustrated, you wake up after just 5 minutes of rest. Sound familiar? Naptime fixes this. Using your phone's accelerometer, it detects when you've actually fallen asleep — then starts your timer. You asked for 20 minutes of sleep? You get 20 minutes of sleep. Designed for power naps, lunch breaks, shift work, students, and recovery naps, backed by NASA research showing short naps boost alertness by 54% and reduce mistakes by 34%. YOUR DATA STAYS ON YOUR PHONE No account required. No cloud. No tracking. All sleep data is stored locally on your device. Works fully offline — perfect for airplane mode naps. FEATURES 🛌 Smart Sleep Detection Your phone's accelerometer distinguishes between restless "settling in" movement and the stillness of true sleep. No wearable needed — just place your phone on your mattress. ⏱️ True Duration Nap Timer The countdown starts when you're asleep, not when you press Start.
