ScreenAlert

About this app

• Run multiple alerts at once. Set up as many Screen Alerts as you need — each watches its own region with its own trigger, sound, and color. The menu bar shows a live count, and every active alert has its own row with a one-click Stop. • Floating preview panels. Optionally show a small picture-in-picture panel that flashes the captured area whenever an alert fires, then slides off to the edge. Pick the corner, size, and auto-hide delay in Settings. Hover an alert in the menu to peek at its last capture. • On-screen stop button. Every watched region gets a colored name pill with a built-in × — stop an alert without ever opening the menu.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
