Do animals nap? 5 surprising sleep facts
From four-second penguin snoozes to a panda’s afternoon pause: five facts worth staying awake for.
The little library of rest
Plan a short break with a nap timer, Sleep Buffer and gentle alarm. Free for Android, with no ads or tracking. Pro is an optional one-time upgrade.
Gamification
Track your naps and see your progress over time. Battery points are a playful reward, not a measure of your health or energy.
Wake-up Experience
Choose from a full library of wake-up sounds — from gentle nature sounds to uplifting melodies. Pair it with a customizable vibration fade-in that softly increases intensity, so you wake up feeling refreshed instead of startled.
Smart Timer
Give yourself time to settle in before the nap timer starts. The alarm follows your chosen duration; it does not detect sleep stages.
Google Play Rating
"Exactly what I was looking for. Used the free version once and ended up buying pro for the extra options. Perfect."
"Works flawlessly. It feels better to use the app for 15 minutes than to aimlessly scroll through Instagram for 3 hours."
"Simple, intuitive, informative. I really like it."
Honest pricing
Pro is an optional one-time upgrade inside the Android app. Your regional price is shown before purchase.
Short naps can help you feel more alert. Keep them brief and allow time to wake fully; results vary, and a timer cannot guarantee a grogginess-free wake-up.

Sleepy questions
Start with a short break and adjust to your routine. Nap length and time to fall asleep are different: the Sleep Buffer adds time before your chosen timer begins.
The early afternoon, roughly between 1 and 3 PM. Your circadian rhythm naturally dips then — the famous post-lunch slump. Napping later than about 4 PM can interfere with your night sleep.
This is called sleep inertia. Shorter naps can reduce the risk, but no fixed duration guarantees how you will feel. Allow time to become fully alert.
No. The alarm uses the duration you choose, plus your Sleep Buffer. It does not measure sleep or predict your sleep stage.
Yes. The Android app is free with no ads and no tracking — all data stays on your device. An optional one-time Pro upgrade unlocks extras like the full sound library, longer sleep buffers and lifetime statistics. There are no subscriptions.
No. Naps are a supplement, not a substitute. They restore alertness and focus during the day, but your body still needs 7–9 hours of consolidated night sleep for full physical and mental recovery.
