1
Start the trial and get your key
The trial runs for 14 days and starts on the pricing page with a card, but nothing is charged until day 14 — cancel before then and you pay nothing. Your key arrives by mail and unlocks the build on every platform you use.

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.

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.
Teams, Slack, Zoom
The green dot follows your keyboard, not your work
Presence in Teams, Slack, Zoom and Discord comes from a single signal: how long it has been since the operating system saw a keystroke or a mouse move. Read a spec, think a problem through, sit on a call in another window — and the dot turns yellow while you are working.
-
Quiet work reads as away
A few minutes without input flips both apps to away at once, and locking the screen does it instantly. Setting yourself back to "Available" by hand does not reset the idle clock.
-
A browser tab cannot reset it
Online movers and looping videos keep the display awake, but they produce no input at the OS level, so the idle timer keeps counting. We ship a free one — and its page says exactly that.
-
Reaction produces the input itself
It moves the cursor and types at the OS level the way a person does: varied timing, natural pauses, window switches. And it steps aside the instant you touch the mouse.
How presence really works:
Free browser keep-awake
How to keep your Teams and Slack status green all day
How to keep your Slack status active all day
This is about a status dot that mistakes focused work for absence — not about looking like you are somewhere you are not.
