About this app
A 20-minute nap should mean 20 minutes asleep.
With a normal countdown timer, the clock starts as soon as you tap Start. If it takes you 15 minutes to fall asleep, only 5 minutes remain.
Naptime works differently. Place your phone on the mattress and choose how long you want to sleep. Using movement detected by your phone’s accelerometer, Naptime estimates when you fall asleep and starts the nap timer then.
No watch, ring, or other wearable needed.
NAP FOR THE TIME YOU CHOOSE
Set your desired nap length and let Naptime handle the timing. The countdown begins after estimated sleep onset, so the time spent settling down doesn’t use up your nap.
WAKE UP BY A FIXED TIME
Have a meeting, class, or shift to get back to? Set a latest wake-up time. Naptime will sound the alarm by your deadline, even if you don’t fall asleep.
TRACK NAPS AND NIGHTTIME SLEEP
Use Naptime as a nap tracker or record full nights of sleep. Review your estimated:
• Sleep latency
• Sleep duration
• Sleep efficiency
• Wake-up mood
Follow your history over time and discover which nap lengths work best for you.
FIND PATTERNS WITH TAGS
Add custom tags such as “coffee,” “noisy,” “window open,” or “post-workout.” Compare your sessions and see which habits and conditions are associated with better sleep.
REGULAR ALARMS
Need a straightforward morning alarm? Create and manage regular alarms alongside your sleep sessions.
DARK, SLEEP-FRIENDLY DESIGN
Naptime’s OLED-friendly black interface keeps your screen unobtrusive while you settle down.
BUILT FOR REAL-LIFE REST
Naptime is useful for:
• Power naps
• Lunch breaks
• Shift work
• Study breaks
• Recovery after a short night
• Pre-workout and post-workout rest
Research has found that short naps can improve alertness, performance, and some forms of learning and memory. Naptime helps you track your own results and find the nap routine that works for you.
Stop losing nap time to the time it takes to fall asleep.
