A slim progress bar at the screen edge that counts down a timebox — fully click-through, zero screen space wasted.
Every timer app needs your attention. TimeboxBar lives at the top (or bottom) edge of your screen as a thin stripe. You see it in your peripheral vision while working, without ever switching focus.
Unlike browser extensions or floating windows, TimeboxBar is:
- Click-through — mouse clicks pass through the bar to whatever is behind it
- System tray only — no taskbar entry, no window
- Always on top — visible above all other apps
- All virtual desktops — the bar stays visible when you switch desktops
- Green → Yellow → Red color as time runs out
- Configurable bar height (3–100 px), position (top/bottom), and opacity
- Pause/Resume via configurable hotkey (default: Ctrl+Shift+Space)
- Quick-start presets (default: 25 min / 45 min) + custom time input
- Blink + sound on completion
- English and German UI (follows Windows language, override in Settings)
- Persists configuration across sessions
Appears on launch and when the hotkey is pressed while no timer is running.
Go to the Releases page and download:
TimeboxBar-*-Setup.exe— installer (recommended)TimeboxBar-*.zip— portable, just unzip and run
Because the app is not code-signed, Windows may show a SmartScreen warning on first launch:
Click "More info" → "Run anyway"
This is expected for unsigned open-source software. The source code is fully auditable here.
- Windows 10 / 11
- .NET Framework 4.8 (pre-installed on Windows 10/11)
