akiHz switches between the refresh rates your Android device actually supports, from the app or a Quick Settings tile. It also shows live app FPS in a floating pill you can drag anywhere. It runs through Shizuku, with no root or bootloader changes.
Android 11+ · Requires Shizuku · MIT licensed
Personally tested on Xiaomi; other OEM strategies are community-reported.
Five things, no more.
Reads the refresh rates reported by your display.
Cycles through the rates you pick on Home, without opening the app.
Shows real app FPS from SurfaceFlinger in a draggable pill, with its own Quick Settings tile.
Supports OEM overrides and custom profiles when needed.
Verifies APK downloads against published release metadata. Update checks run daily, every 3 days, or weekly.
Four steps, about five minutes.
Requires Android 11+, Shizuku, and a display with multiple refresh rates. Only Xiaomi has been personally tested. A Background setting keeps the tile ready, and Appearance offers a true-black AMOLED theme.
No. akiHz uses Shizuku to access the refresh-rate-related system settings that ordinary Android apps cannot change directly. You still need to start Shizuku after restarting your phone, but you do not need to unlock the bootloader, install Magisk, or modify the system partition.
Android restricts access to the settings akiHz needs. Shizuku provides a local, permission-controlled bridge to those settings through wireless debugging or ADB. akiHz asks for authorization through Shizuku and does not receive unrestricted root access.
No. The pill shows real presented app FPS read from SurfaceFlinger, not screen Hz. A 120 Hz screen can still show a 30 FPS game. Start it from Settings, FPS Monitor, or the FPS tile. It needs Shizuku and overlay permission, and Settings controls its size, opacity, color, shape, and label.
akiHz detects the rates reported by your display and includes strategies for several Android manufacturers. It has only been personally tested on a Xiaomi phone, however, so other devices are not guaranteed. If automatic detection chooses the wrong settings, you can try the OEM override or create a custom profile.
