02 / PUT IT TO WORK
For the tools that don’t notify you, watch the visible area that matters. No website integration or API is needed.
Watch the result area of a build or test window while you work on something else.
Keep an eye on changing status indicators, tickets, orders, or a web admin panel.
Notice a change in a transfer, export, or progress window without checking it repeatedly.
03 / GET STARTED
It compares visible pixels in your selected region. When the changed area reaches your threshold, your chosen alerts fire.
Choose Select Region and drag a rectangle around the part of your desktop you want to watch.
Choose a change threshold and check interval. Configure sounds and notifications in Settings.
Choose Start. Keep the target visible; the watcher itself can run from the system tray.
