FPS Meter

A high-performance, lightweight FPS monitoring overlay for Android. Inspired by the Samsung Perf Z aesthetic, this application provides real-time performance telemetry for mobile gaming and development.

Features:

- Dual FPS Providers:

- Choreographer: Measures display refresh and vsync pace with minimal overhead.

- SurfaceFlinger: Privileged buffer queue monitoring using Shizuku to measure true in-game rendering frame rates.

- Automatic Graphics API Detection: Detects whether games run on Vulkan or OpenGL ES (e.g. Genshin Impact, Wuthering Waves) and selects the appropriate frame metric strategy.

- On-Screen Graphics API Badge: Displays [VK] or [GL] indicator on the floating counter.

- Frame Time & Thermals: Real-time milliseconds (MS) frame time and device battery temperature.

- Dynamic Color Coding: Adaptive FPS value colors based on performance thresholds.

- Quick Settings Tile: 1-tap overlay toggle directly from the Android notification shade without switching apps.

- Floating Assistive Bubble: Draggable on-screen bubble for instant show/hide during gameplay.

- Auto Game Detection: Automatically activates the overlay when designated games launch via Accessibility Service.

- Six Preset Positions: Quick-snap positioning with full touch-drag support.

- Fully Open Source and privacy-focused: zero analytics, zero trackers, and zero network calls.
