Keep your Android games organized and your device information within reach. GameBooster combines a game launcher, optional focus controls and measured device diagnostics in one dashboard.

GAME LAUNCHER & LIBRARY
Find installed games, add apps manually, mark favorites and launch your next game from one place. Search your library and sort games alphabetically or by recent activity.

BOOST MODE
Start Boost Mode to check your connection and activate Focus Shield when you have granted Do Not Disturb access. Review a clear completion summary and stop Boost Mode from its ongoing notification. Your previous Do Not Disturb setting is restored when Boost Mode ends.

ULTRA BOOST
Watch a voluntary rewarded ad to unlock two Ultra Boost uses. Then tap the main Ultra Boost button to start the standard controls plus:
• Thermal Guard — monitors Android thermal-pressure status on supported devices.
• Connection Guard — monitors internet availability and network changes.

An Ultra use is consumed only after startup succeeds with at least one advanced feature active.

DEVICE MONITOR
View available memory, memory usage, CPU readings, storage space, battery level and battery temperature. Readings depend on the information your Android device exposes.

DISPLAY RATE OVERLAY
Enable a compact, draggable refresh-rate badge above your apps. Show or hide it from Tools after granting display-over-other-apps access. The badge displays your screen’s refresh rate in Hz.

AUTOMATIC BOOST
Optionally enable Automatic Boost for games in your library. With Android Usage Access, GameBooster detects when a selected game is active.

MORE GAMING TOOLS
• Network Diagnostics: check connection type, web response times and reachability.
• Junk Cleaner: remove GameBooster’s own cache and temporary files, with measured cleanup results.
• GFX Guide: save a graphics-settings reference checklist to apply inside your games.
• Nickname Studio: create and copy nickname variations.

YOUR CHOICES
No account is required. Game library preferences and feature histories are stored locally. Optional permissions are used for their related features. The app includes banner ads and voluntary rewarded ads for Ultra Boost.

CAPABILITY NOTES
GameBooster does not increase rendered FPS, free other apps’ RAM, cool your phone or change CPU, GPU, game graphics or network speed. Thermal Guard and Connection Guard provide monitoring. The overlay shows display refresh rate, not game-rendered FPS, and network tests measure web responses, not game-server ping.
