Sleep Timer: Detect Sleep, Off

Other sleep timers make you set them every single night. StillAsleep is set once and works every night — 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 the screen off 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.

EIGHT THINGS THAT SET US APART

SET IT ONCE, FORGET IT

Pick a mode, tap Play — that's it. DAILY runs at your bedtime every night on its own; Handheld and Hands-Free always re-arm themselves automatically. 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. 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. No fake countdowns. No interruptions while you're awake.

A KIND 30-SECOND WARNING

Before stopping anything, a countdown banner appears and the volume fades gently. Still awake? Tap it or shake your phone — the timer resets, no interruption to your show. On DAILY mode, one tap skips tonight and keeps tomorrow. 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 Time 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 — and DAILY makes it repeat at the same time every night.

FREE TO USE. NO ADS. NO SUBSCRIPTIONS.

Install, set it 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.
