Caffeine: Keep Screen On

Caffeine keeps your screen on for as long as you need, without changing your system display timeout.

Start it with one tap from the Quick Settings tile or from the app, and stop it the same way when you're done. It's handy when you're reading a long article, cooking from a recipe, following a dashboard, giving a presentation or watching logs.

FEATURES

• Quick Settings tile: start or stop Caffeine without opening the app. Long-press the tile to open the settings.
• Persistent: keeps the screen awake with no time limit, until you stop Caffeine yourself.
• Restart on reboot: if Caffeine was running when your device restarted, it turns itself back on.
• Automatic turn off: stops Caffeine when the screen goes off, for example when you press the power button.
• Light and dark themes that follow your system setting.
• Guided setup that explains each permission before you grant it.

PERMISSIONS

• Display over other apps (required): places an invisible view that keeps the screen on.
• Notifications: show an ongoing notification while Caffeine is running.
• Background activity (optional): you can exclude Caffeine from battery optimization in your system settings so it keeps running reliably.

PRIVACY

No ads and no accounts. Your settings are stored only on your device. Caffeine uses Google Firebase to collect usage analytics and crash reports, as described in the privacy policy.

Keep in mind that a screen that stays on uses more battery.
