unsit

A tiny sit/stand timer. Run unsit and it counts 40 minutes of sitting, then 20 of standing, round and round, with a notification at each switch. The tray icon shows the current phase and the time left; its menu has Skip and Stop. No settings, no history, no network.

Runs on macOS 13+, Windows 10/11 and Linux desktops with a system tray.

Usage

unsit                          # 40 minutes sitting, 20 standing
unsit --sit 50m --stand 10m    # your own rhythm
unsit --no-tray                # no tray icon; prints a line at each switch

Stop it from the tray menu or with Ctrl-C. unsit --help lists all flags.

Notes

• Linux: the tray icon needs a StatusNotifierItem host (Waybar, Omarchy, KDE; GNOME needs the AppIndicator extension). On Omarchy it sits in the tray drawer.
• macOS: notifications arrive as Script Editor. If none show up, allow them in System Settings > Notifications.
