System Monitor HUD is a lightweight, high-performance Android system monitor designed for users who demand peak device performance.

It displays real-time critical system metrics — including CPU temperature, system load, memory usage, screen refresh rate, Wi-Fi signal strength, battery temperature and status, and network type — in a clean, non-obtrusive floating overlay.

Simply enable floating window permissions to start using it — ideal for gamers, streamers, and everyday users who want instant visibility into device performance.

All data is intelligently optimized for mainstream devices, and automatically shows “N/A” when information is unavailable — ensuring clarity, reliability, and zero confusion.
