§01 — About

SysWatch shows a Windows PC's live CPU, GPU, memory, network, storage and battery on an Android phone. A small desktop app reads the hardware; the phone shows it as it moves and tells you when a reading crosses a limit you set. Free, no ads, no account. The phone reads; in Local and Tailscale mode it can also play, pause and skip what the PC is playing. Connect over the same Wi-Fi, through Cloud by DevLune from anywhere, or privately from anywhere with Tailscale.

§02 · Desktop app

Required companion

Desktop app required

Your PC runs the desktop app. Your phone shows the readings.

The free Windows app sits in the system tray and reads the hardware. The first time it opens it asks how the phone should connect: Local on the same Wi-Fi, Cloud by DevLune from anywhere, or Tailscale, private from anywhere. Then the phone scans one QR code and there is nothing to type.
