Download TimerOS for Windows.
The desktop app is the only place TimerOS tracks work time — an always-on-top timer bar plus an on-demand dashboard window, free with every plan.

Tracks by itself. Stays out of the way.
A slim bar docked at the top of your screen. It knows whether you are working, idle or on a break, keeps counting when you are offline, and updates itself.
An always-on-top timer bar
A compact bar docked at the top of your screen showing your activity state, elapsed time, and Break / Dashboard / Collapse / Logout. Collapse it to a pill when you want the space back.
Tracking that starts by itself
Sign in and the login window becomes the timer bar — there is nothing to press. Activity classification runs on your device: no cloud AI, no model download, and no raw window titles leave your machine.
Offline-tolerant, self-updating
Time keeps being recorded while you are offline and syncs when you reconnect. When a new version ships the app tells you and updates in one click — you never re-download the installer.
Installing takes four steps.
System requirements
- Windows 10 or Windows 11, 64-bit
- Microsoft Edge WebView2 — already present on current Windows builds; the installer fetches it if your machine is missing it
- A TimerOS workspace and a sign-in (plus a 6-digit code if your workspace requires two-factor authentication)
Four steps
- Create or join a workspace.
- Run the installer you downloaded above.
- Launch the app and sign in.
- The login window becomes the timer bar and tracking starts.
Other ways to use TimerOS.
Use it in your browser
The web app at app.timeros.ai gives you the same dashboard as the desktop client — projects, tasks, shifts, reports, clients and settings — with nothing to install. It never tracks time: hours come from the desktop timer.
macOS is planned
The desktop client ships for Windows today. A macOS build is on the roadmap; until it lands, Mac users can run everything except time tracking in the web app.
No workspace yet? Two minutes.
Registration takes a couple of minutes and gets you a workspace, a sign-in, and the desktop app — which is included on every plan.
