Sleep Timer: Detect Sleep, Off

Other sleep timers make you set them every single night. StillAsleep is set once and works forever — no nightly setup, no remembering. Other sleep timers make you guess how long you'll stay awake. StillAsleep doesn't need you to guess — it knows when you've actually fallen asleep and turns off screen for you automatically.

Other sleep timers forget you the moment they fire. StillAsleep remembers — it builds your sleep history from the moments you drifted off, night after night.

Waking up to a drained battery, gigabytes of mobile data wasted, or a recommendation feed full of stuff you never watched? Or tired of being woken up by a video still playing?

StillAsleep stops playback and turns off screen after you've truly fallen asleep — not when an arbitrary countdown ends. And because it knows the exact moment you drifted off and woke up, it doubles as an effortless, automatic sleep tracker — no wearable required.

SEVEN THINGS THAT SET US APART

ONE-TAP SETUP, FORGET IT FOREVER
Pick Handheld or Hands-free, tap play — that's it. Configure once and forget the app exists, until it quietly does its job each night. Other apps make you start a countdown every single night.

IT'S ALSO A SLEEP TRACKER — AUTOMATICALLY
Because StillAsleep knows exactly when you fell asleep and when you woke, it quietly builds a night-by-night sleep history — no wearable to charge, no "start sleep" button to remember. Open the app and swipe to see how you've been sleeping. And It also shows you which nights it turned your screen off for you. 100% on-device, nothing uploaded.

WE ACTUALLY DETECT WHEN YOU FALL ASLEEP
StillAsleep knows when you've stopped paying attention. It triggers only when you've truly fallen asleep — not just when 30 minutes have passed. No fake countdowns. No interruptions while you're awake.

A KIND 30-SECOND WARNING
Before stopping anything, a countdown banner appears. Still awake? Tap it or gently shake your phone — the timer resets, no interruption to your show. Other apps cut you off with no warning.

NO INVASIVE PERMISSIONS
StillAsleep uses only light, non-invasive permissions: "Display over other apps" for the countdown banner, plus an optional one-tap allowance to keep running reliably in the background. No Device Admin (the scary one that lets apps fully control your phone and makes them hard to uninstall). No Accessibility (which can read everything on your screen and tap things on your behalf). No Notification Access (which reads every notification you receive).

WORKS WITH EVERY APP
YouTube, TikTok, Netflix, Disney+, HBO Max, Prime Video, Twitch, Crunchyroll, Plex — and any app with embedded video like Instagram, X, Facebook, Reddit. No setup. No integration. No per-app pairing. It just works. Listening instead of watching? Fixed Countdown mode is a classic sleep timer for podcasts, audiobooks and music — it pauses playback at the time you choose, even when the screen is off.

FREE TO USE. NO ADS. NO SUBSCRIPTIONS.
Install, set the timer once, watch video, fall asleep — that's the whole flow. No full-screen ad jolting you awake mid-fade. No monthly bill sitting in your account waiting to renew. Other sleep timers either fund themselves with intrusive ads, or lock the basics behind a subscription. StillAsleep does neither.

100% PRIVATE AND LIGHTWEIGHT
No account. No sign-up. No ads. No advertising ID, no ad tracking. Your sleep data — every night, every screen-off — stays on your phone. The app itself uses less than 0.2% battery per day — far less than one night of unwatched video.

PERFECT FOR
• Falling asleep watching YouTube, TikTok, Netflix, and other video apps
• Anyone who forgets to set a timer every single night
• Wanting a charged phone in the morning
• Effortless sleep tracking — no wearable, no charging, nothing to tap
• Avoiding Device Admin and Accessibility permission demands

Sleep better. Save battery. See how you sleep. Set it once and forget it.
