Device Vitals Board Screensaver
The Device Vitals Board screensaver shows real live stats about your own device — battery, network, CPU cores and display — read directly from your browser. It is free, runs in your browser, and ESC exits.
How the Device Vitals Board screensaver works
The saver reads real, live values your browser already exposes: battery level and charging state, network connection type, logical CPU cores, and display resolution.
Metrics update live as they genuinely change — for example, the battery percentage ticks as your real device charges or drains.
Nothing is sent anywhere — every value is read and displayed locally, entirely within your browser.
Not every browser exposes every metric; unsupported ones are clearly labeled as such, never faked.
A worked example
Plug in your charger and the real charging indicator flips live, exactly in step with your device's actual charging state.
