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.
