How activity scoring works in general, and why jigglers get caught — whatever the tracker.
Hardware dongles, jiggler apps and the input-pattern signatures trackers now flag.
Breakdown ~9 min
Keys, clicks, scrolls and window focus — the shared scoring model behind most trackers.
Breakdown ~7 min
One honest table of capture channels across the big trackers.
From theory to practice
No timers, no fixed 100%. While you are away, a “person” keeps working at your computer — and the moment you touch the mouse, you are back in control.
See how it worksHeld steady while you are away from the desk.
Your activity percentage, in range
Smooth mouse motion and a living key rhythm hold the number in the band you choose — no jerks, no suspicious flat 100%.
Idle time never counts against you
Reaction runs only when the computer is truly idle, so the tracker never logs the gap. Touch the mouse and control returns to you instantly.
Behaves like a person, not a jiggler
The behavior is randomized, familiar apps get their own scenario — tabs, panels, scrolling — and the screen keeps changing, like real work.
