NapBest is the smartest nap timer on your iPhone. Fall asleep naturally — NapBest does the rest. AUTO MODE (Apple Watch required) NapBest listens for the moment you actually fall asleep using your Apple Watch's sleep data. The moment sleep is detected, your timer starts automatically. No guessing. No fumbling with a timer when you're already drowsy. MANUAL MODE No Apple Watch? No problem. Set your duration, tap Start, and put your phone down. NapBest handles the rest. SCIENCE-BACKED DURATIONS Choose from four research-based nap lengths: • 20 min — Power nap. Light sleep only, zero grogginess. • 30 min — Recovery nap. Boosts alertness and mood. • 90 min — Full sleep cycle. Memory consolidation and creativity. • 2 hrs — Extended rest. Deep regeneration. Or set your own custom duration from 5 to 240 minutes. AN ALARM THAT ACTUALLY WAKES YOU NapBest plays a real alarm sound — not just a notification tap. Audio plays at full volume even when your phone is on silent, so you actually wake up. CUSTOMIZABLE ALARM Pick your preferred sound (Digital, Gentle, or Classic) and set the volume. Preview each sound before you commit. WORKS IN THE BACKGROUND Lock your screen, put your phone down, and rest. NapBest runs quietly in the background and will wake you at the right time.
