Nap-On

Nap-On is a smart nap timer for your watch. Instead of guessing when you'll drift off, it watches your heart rate and movement to detect the moment you actually fall asleep — then times your nap from there, so you wake up rested instead of groggy.

Just pick how long you want to sleep, start the timer, and relax. Nap-On quietly calibrates your resting heart rate, detects sleep onset, and sets a precise alarm that vibrates to wake you — bypassing Do Not Disturb so you never oversleep.

FEATURES
• Automatic sleep detection from heart rate and motion
• Times your nap from when you actually fall asleep, not when you press start
• Gentle vibration alarm that works through Do Not Disturb
• Learns your typical time-to-sleep and adapts
• Simple, distraction-free watch interface
• Works on its own — no phone required during your nap

Whether it's a quick power nap or a longer rest, Nap-On helps you get the most out of every minute.

Nap-On is designed for healthy adults and is not a medical device. It does not diagnose, treat, or monitor any medical condition.
