Cryo: Game Booster & GFX Tool

Cryo is a game booster, GFX tool and background app freezer for Android — no root required.

Games lag for two reasons: the GPU is doing too much work, and background apps are stealing RAM, CPU and battery. Cryo fixes both, per game, in one tap — whether you play a battle royale, a MOBA, a racing game or an open-world RPG.

PHONE OVERHEATING AND DROPPING FPS?
When a phone gets hot, Android throttles the GPU and the frame rate collapses. Cryo works as a phone cooler by removing the GPU work that creates the heat in the first place: it lowers the 3D render resolution of the game itself, so the GPU draws fewer pixels, runs cooler and holds a stable FPS. Menus, chats and photos on the rest of your phone are untouched.

GPU 3D RESOLUTION SCALE (GFX TOOL)
• Set a render scale per game, anywhere from 100% down to 30%, in 5% steps
• Two engines: Buffer Downscale (per app, nothing global changes) or Fullscreen ADB downscale
• Continuous Resolution Lock stops heavy 3D titles from snapping back to native resolution mid-match
• Applies only to the games you pick — every other app stays sharp

FREEZE BACKGROUND APPS AND REMOVE BLOATWARE
• A real task manager: every running app and system service, with live RAM and CPU usage
• Freeze an app so it cannot restart itself, wake up, sync or drain battery in the background
• Four freeze levels, from a light standby lock up to a full disable
• Find preinstalled bloatware and shut it up without root
• Thaw anything in one tap — nothing is deleted unless you ask for it

FPS OVERLAY AND TEMPERATURE MONITOR
• Floating window over your game: FPS, CPU load, GPU load, free RAM
• CPU, GPU and battery temperature in real time
• Move it, resize it, hide it whenever you want

ONE-TAP GAME MODE
• Focus Mode — clears background apps and hands CPU and GPU back to the game
• AFK Screen Off — blacks out the display while the game keeps running and farming; double tap to wake
• 60Hz Refresh Rate Lock — steadier battery drain and fewer stutters on 90Hz and 120Hz phones
• Do Not Disturb — silences notifications during a match

MADE FOR PLAYERS WHO WANT TO
• make an old or mid-range phone playable again
• stop the phone from getting hot while gaming
• fix lag, stutter and frame drops in heavy 3D games
• stop background apps from killing the game
• save battery during long farming sessions
• see FPS on screen while playing
• clean up bloatware on a phone that will not let them

NO ROOT — HOW IT WORKS
Cryo runs its system commands through Shizuku (ADB), so it never needs root or an unlocked bootloader. The app walks you through the one-time setup. Without Shizuku you still get the FPS overlay and the hardware monitor; with it you unlock resolution scaling and freezing.

BUILT FOR REAL PHONES
Samsung, Xiaomi, POCO, Redmi, OPPO, vivo, realme, OnePlus, Motorola and more. Cryo keeps an undo log of every system setting it changes and repairs it after a reboot, so nothing is left behind on your device.

WHY CRYO INSTEAD OF ANOTHER BOOSTER
Cryo is a real performance optimizer for gaming, not a one-tap placebo. Every switch does something you can check on screen: the render scale you picked, the list of apps that are actually frozen, the FPS counter climbing while the temperature drops. Nothing is hidden behind an animation.
