Keep your screen awake by timer, per app, schedule, charging or a quick tile
Keep Screen On Pro stops your screen from dimming and turning off while you look at it without touching it: a recipe while cooking, maps in the car, e-books, sheet music, videos or a dashboard. Turn it on with one tap, or let a timer, chosen apps, a schedule or charging do it only when needed. Your system screen timeout is never changed. An invisible 1-pixel window keeps the screen on, and the app underneath works as before. The power button still turns the screen off anytime. 【Main features】 ■ One tap Tap the big button on Home and the screen stays on until you stop it. Home and the notification show why (manual, timer, app, charging…). ■ Timer 5, 15 or 30 minutes, 1 hour, 2 hours or no limit, with a large countdown ring, "+15 min" to extend and a silent warning 1 minute before the end. ■ Per-app The screen stays on only while a chosen app is open (maps, recipes, videos, e-books) and returns to normal when you leave. Add as many apps as you like. ■ While charging Stays on with a cable, dock or wireless charger, even at full battery. A handy bedside clock or dashboard. ■ Schedule Set windows by time and weekday, such as weekdays 9:00–18:00, including overnight. ■ Pause this time Stop an automatic trigger from the notification or Home and it pauses only until that trigger ends (leave the app, the window ends, unplug), then works again next time. ■ Battery and heat safety The screen may turn off when the battery is low (15% by default, 5–30%, not while charging) or hot (stops at 45°C, resumes at 42°C). You can also cap "no limit" at 1–8 hours and end it with the power button. ■ Notification and Quick Settings tile Stop, extend or resume from the notification, with Low (no status bar icon) or Normal priority. The main tile switches it on or off without opening the app. ■ Status check and device guides Finds why the screen still turns off: permissions, battery optimization, company device limits, automatic permission removal. Guides for phones that tend to stop apps (Samsung, Xiaomi, OPPO…), and Home tells you if the system stopped the app. ■ More Turn on at startup, Compatibility mode, light/dark theme, 39 languages, tablet layouts. 【Premium】 The core features (manual, timer, per-app, 1 schedule, charging, safety, notification, main tile, status check) are always free. Premium adds: ・7 Quick Settings tiles: timer (5 → 15 → 30 min → 1 h → 2 h → no limit → off), per-app, schedule, charging, landscape, device screen timeout (15 s–30 min), blackout ・Home screen widget showing time left or the reason ・Any number of schedules ・Stay on in landscape: videos, games, car holders ・Stay on during calls (phone, LINE, Zoom…); it still turns off at your ear ・Allow screen off face down or in a pocket or cover; back on when you pick it up ・Dim when idle after 1–30 minutes to save battery ・Blackout: a black screen with a small clock and battery level that moves every minute to avoid burn-in; double-tap to return ・Custom timer lengths (1 min–24 h) and editable timer choices ・Change the device screen timeout ・Color themes: Teal, Ember, Violet, Forest, Rose Premium is a one-time purchase, not a subscription. With the same Google account, "Restore purchase" brings it back on a new phone. 【Permissions】 ・Display over other apps: for the invisible 1-pixel window. It takes no touches, so other apps work as usual. Required. ・Notifications: for the persistent notification and timer warning. ・Usage access: only for per-app, to know which app is in front. App names stay on your device. ・Modify system settings: only for Premium's device screen timeout. 【Notes】 ・It does not work on the lock screen; Android does not allow it. Unlock and it works again. ・When the battery is low or hot, it stops on purpose to protect it (adjustable). ・On some screens of some phones, such as install confirmations, Android hides other apps' windows. Try Compatibility mode.
