Keep your games in one place. Apps that declare themselves as games are picked up automatically; anything else can be added by hand.
LIVE HUD OVER YOUR GAME
With your permission, a small floating panel appears while you play and shows what Android reports on your device: free RAM, battery level and battery temperature, network latency to a public DNS server, and your screen refresh rate.
A REPORT AFTER EVERY SESSION
When you finish, the readings taken during the session become a report: ping stability, free memory and battery temperature with the raw numbers beside each score, plus playing time.
GAME INSIGHTS
What your recorded sessions show (total playtime, most played game, memory or temperature that got tight) plus how your device is right now. A button appears only where the app can actually do something.
GFX GUIDE
Based on your device's RAM, CPU cores, screen resolution and refresh rate, the app suggests a starting point for graphics, frame rate, resolution and shadows. These are suggestions to set inside the game yourself; the app cannot change a game's settings or make it run faster.
GAME MODE
Silences notifications while you play (your previous Do Not Disturb setting comes back when you turn it off). On Android 13 and earlier it can also ask Android to release background processes and shows the real amount freed; from Android 14 the system manages background apps itself and the app says so instead of showing a number.
REFLEX TRAINER
Two short drills between matches: tap the instant the panel turns green, or hit twelve targets as fast as you can. Timed from the frame change to your touch, so screen and touch latency are part of the number — it measures you, not the device, and scores stay on your phone.
Permissions: "Display over other apps" and "Usage access" are only needed for the HUD, and the app asks for them on the HUD screen with an explanation. Notification policy access is only needed for Game Mode's Do Not Disturb.
