UltraCore

UltraCore is a set of system tools for any smartphone running Android 12 and newer. It works without root via Shizuku and uses only standard Android commands. The app automatically checks what is allowed on your phone and honestly displays whether it is running, partially running, or blocked by the firmware. BATTERY. Charge, temperature, current, health, cycle count, and capacity rating. Each value is labeled with its source: Android standard, firmware data, or calculation. TWEAKS. Animation speed, screen refresh rate lock, background process limit disabling, secure private DNS with ad blocking. Each tweak remembers the original value and can be reset with a single button. MAINTENANCE. Memory TRIM, background app optimization (the same as what the system does overnight while charging), ART compilation after a system update. Current RAM and memory usage – in real time. FILES. Cleans up remnants of deleted apps, logs, empty folders, and duplicates. Sort files according to your rules. Always with a preview and the ability to roll back. APPS. Pause and freeze, limit background work, remove unnecessary system apps with the ability to restore (important parts of the system are protected). Backup and install APKs, APKs, and XAPKs. Launch hidden settings screens and shortcuts to them. Sandbox: the app wakes up when opened and sleeps after the screen turns off. TERMINAL. Console with live output, a catalog of 34 commands with descriptions in Russian, macros, and a tile in the curtain. SECURITY. The "Restore phone to how it was" button undoes everything changed by UltraCore. The application does not access the internet and does not collect data. Open source (GPL-3.0). Most functions require the free Shizuku app (shizuku.rikka.app), launched via "Wireless Debugging". After a phone reboot, Shizuku must be restarted. Battery and file cleaning work without it.
