Download Reaction — a mouse jiggler for Windows and Linux
Reaction moves the mouse, types and switches windows the way a person does, so your tracker keeps counting while you step away. 14 days free, no card up front.

Held back on purpose until the builds are signed — an unsigned Mac build cannot update itself, and we will not ship an install that strands you.

1
Start the trial and get your key
The trial runs for 14 days and takes an email, not a card. Your key arrives by mail and unlocks the build on every platform you use.
-
2
Install and clear the warning
The builds are not code-signed yet, so Windows shows a SmartScreen notice: choose "More info", then "Run anyway". Nothing is hidden from you here — signing certificates are bought and the warning disappears.

3
Point it at your tracker and leave
Pick your tracker in the app, set how lively the movement should be, and press the hotkey. Reaction pauses the moment you touch the keyboard yourself.
Before you install
- It is software, not a USB dongle
- Nothing to buy, ship or leave plugged in — and no extra device showing up in the hardware list.
- It records nothing
- Reaction never captures your keystrokes, your screen or your files. It only produces input, it does not collect any.
- One key, every machine you own
- The subscription follows you, not the computer: activate the same key on your desktop and your laptop.
- Cancelling is one click
- No sales call, no retention flow. Cancel in the account page and the trial simply ends.
