A lightweight, Windows-native task planner built with WPF and .NET. OD.Planner keeps your to-do list close at hand in a small, always-ready window and makes sure deadlines don't slip by — with audible alarms and color-coded urgency.
- Task management — add, edit, reorder, complete and delete tasks from a compact, resizable window.
- Flexible deadlines — deadlines can be a fixed date or a number of days from creation, and can be pushed back by one day or one week with a single click.
- Urgency at a glance — tasks are sorted and color-coded by deadline, with a blinking highlight for tasks that are about to become overdue (animations can be reduced or disabled).
- Categories — organize tasks into categories and filter the list with one click.
- Audible alarms — optional sound alerts the day before a deadline (J-1), on the due day (J0), and when a task is overdue. Each alarm can be enabled or disabled independently.
- System tray friendly — minimize to the background; alarms and midnight rollovers keep working while the app is in the background.
- Dark & light themes — switch at any time; the choice is remembered between sessions.
- Persistent layout — the window remembers its position and size. On first launch it docks to the top-right of the primary screen.
- Multi-language UI — switch between English and French instantly without restarting the application.
- SQLite storage — your tasks live in a portable
tasks.dbfile that you can relocate from the settings.
- Windows 10 or later
- .NET 10 (self-contained publishing also supported)

User manuals are available in the docs/ folder:
Tasks are stored in a SQLite database (tasks.db). By default the file is created next to the application; use Settings → Database → Change… to pick another location. Settings are saved as settings.json next to the application (or under %LOCALAPPDATA%\OD.Planner if the app folder is not writable).
