The sleep timer that knows when you fall asleep.

StillAsleep is the best sleep timer app for Android — a sleep timer for YouTube, Netflix, TikTok, Spotify, podcasts and any media app that auto-stops playback and turns off the screen when you actually fall asleep. Unlike every other sleep timer on Android, you set it once and it works forever. No nightly setup, no guessing. No more dead phone in the morning.

StillAsleep video sleep timer app — set 8 minutes, auto-stops YouTube when you fall asleep StillAsleep sleep detection active — timer waits until you actually fall asleep watching video

"I kept falling asleep watching YouTube in bed and waking up to a dead phone. Every sleep timer Android app I tried was just a blind countdown — none of them could detect when I actually fell asleep. So I built a sleep timer for YouTube and every video app that does."

— Founder, Entropy Labs

Why StillAsleep is the best sleep timer app for Android.

Every other sleep timer app is just a countdown — it can't tell if you're asleep or awake. StillAsleep detects real sleep.

❌
Other apps
A countdown. You set 30 minutes. It cuts off whether you're asleep or not.
✅
StillAsleep
Smart detection tells real sleep apart from everyday use. Action only happens when you're truly asleep.
❌
Other apps
Set it every night before bed. Forget once, wake up to a dead phone.
✅
StillAsleep
Set it once. Daytime use is untouched. Nighttime sleep is handled.
❌
Other apps
Demand Device Admin, Accessibility, or Notification Access — permissions that can fully control your phone, read everything you tap, or peek at every notification you receive.
✅
StillAsleep
None of those. Just "Display over other apps" for the countdown banner, plus an optional one-tap background-activity allowance for reliability — nothing that can control your phone, read your screen, or see your notifications.
❌
Other apps
Full-screen ads that interrupt at the worst moment — right when you're about to fall asleep — or subscriptions you forget to cancel.
✅
StillAsleep
No ads. No subscription. No account. No recurring fees, ever.
❌
Other apps
Cut you off mid-show with no warning.
✅
StillAsleep
A 30-second banner appears first. Still awake? One tap and the timer resets — no interruption.

Frequently asked questions about StillAsleep.

What is the best sleep timer app for Android?
StillAsleep is a free sleep timer app for Android that detects when you actually fall asleep, then auto-stops video and turns off the screen. Unlike other sleep timer apps, you set it once and it works forever — no nightly setup needed. Works with YouTube, Netflix, TikTok, Spotify, and any other media app.
Is there a sleep timer for YouTube on Android?
Yes. YouTube has a built-in sleep timer, but it's a fixed countdown — you have to guess how long you'll stay awake and set it every time. StillAsleep is a better sleep timer for YouTube because it detects when you actually fall asleep, works across all apps (not just YouTube), turns off the screen, and only needs to be set once.
Is StillAsleep free?
Yes — StillAsleep is free, with no ads, no subscription, and no account. The free version is fully automatic: it detects sleep and turns off the screen, in every mode, with no time limit. The only optional extra is a one-time upgrade that keeps the automatic modes always-on, so frequent nightly users never have to tap Start before a session — a convenience, not a feature unlock.
Does StillAsleep work with YouTube, Netflix, and TikTok?
Yes — StillAsleep works with YouTube, Netflix, TikTok, Disney+, HBO Max, Prime Video, Twitch, Crunchyroll, Instagram, and any other video app. No setup or per-app pairing needed.
Does StillAsleep work with Spotify and podcasts?
Yes. StillAsleep supports Spotify, podcast apps, and other audio players. It stops playback and lets the screen lock, just like it does for video apps.
Do I need to set the sleep timer every night?
No. You set it once and it works forever. StillAsleep runs passively in the background — it only activates when you're watching video. Normal daytime phone use is completely untouched.
Can a sleep timer turn off the screen on Android?
Most sleep timer apps can only pause media but can't turn off the screen. StillAsleep does both — it stops the video and lets the screen turn off and lock, saving your battery overnight.
Does StillAsleep drain phone battery?
No — StillAsleep uses less than 0.2% battery per day. Far less than one night of unwatched video draining your phone.
What permissions does StillAsleep need?
Only light, non-invasive ones: "Display over other apps" for the countdown banner, plus an optional one-tap allowance to keep running reliably in the background. No Device Admin, no Accessibility Service, no Notification Access — nothing that can control your phone or read your screen.
How does StillAsleep detect when I fall asleep?
StillAsleep uses on-device signals to tell real sleep apart from normal use. No audio recording, no camera, no machine learning, no cloud calls. All processing is 100% on-device — nothing about your usage leaves the device.
Will StillAsleep stop my video while I'm still watching?
No. StillAsleep only triggers when you've actually fallen asleep. If you're still awake, a 30-second warning banner appears — tap it or shake your phone and the timer resets. No interruption to your show.
Can I use a sleep timer with Netflix on Android?
Yes. StillAsleep works as a sleep timer for Netflix, Disney+, HBO Max, Prime Video, and any other streaming app on Android. It detects when you fall asleep, stops the video, and turns off the screen.

Stop falling asleep watching YouTube with your phone on.
Wake to a charged phone instead.
