Napping vs PowerNap

Help you record every nap and update data into Apple Health sleep. With quick alarm, whenever you want to nap 5 mins or want to sleep whole afternoon,Napping will set up alarm and wake you up!

Your lunch break ends at a fixed time. So the real question isn't "how long should I nap" — it's "by when should I lie down?" PowerNap is a nap timer built around the watch on your wrist. It estimates sleep onset from heart rate and motion. It starts with a standard 15-minute suggestion. After 5 valid assessments, it uses your history to suggest a duration from 10 to 20 minutes and works backwards from your fixed wake-up time to tell you when to lie down. HOW IT WORKS 1. Set your wake-up time (e.g. 12:55) 2. Lie down by the suggested time and tap Start Nap on your watch 3. Heart rate + stillness estimate sleep onset — no tapping needed 4. Confirm whether you slept and rate grogginess, then rate return-to-work readiness about 30 minutes later After 5 assessed naps, history-based suggestions begin. MADE FOR YOUR WRIST - PowerNap estimates sleep onset from a sustained heart-rate drop and continuously observed stillness. Resting while awake can still resemble sleep. - Last night's sleep duration, resting heart rate and HRV shown as reference information - Backup notifications on both watch and iPhone - Without sufficient heart-rate data, no sleep estimate is made; the scheduled alarm still works. TRACK AND UNDERSTAND - Every nap recorded automatically: estimated onset and sleep duration, heart-rate curve - Wake-up and 30-minute assessments, weekly charts and start-time patterns - Insights based on your own answers and history - The heart-rate graph for your latest completed, non-cancelled nap is included without a purchase. Access moves to the next completed nap; older graphs require Pro. - Sleep totals and averages include estimates only when you confirm that you slept. No, unsure and unanswered records are excluded.
