What Planner is

Planner is a free, open-source task manager designed for GNU/Linux. It helps organize tasks, projects, and goals, with sections for dividing projects into parts. Tasks can include notes, URLs, deadlines, and labels, and users can add one or more reminders or set recurring tasks. Planner synchronizes Todoist projects, sections, and tasks; Todoist tasks can be used offline and synchronize when connectivity returns. Planner states that it is not created by, affiliated with, or supported by Doist. The app can show personal and shared calendar events beside to-dos in its Today and Upcoming views. Tasks can be reordered by dragging, and each project has a progress indicator. The project lists installation options through elementary OS AppCenter, Flathub, Arch Linux AUR, and Fedora repositories. It supports translations in several languages and invites contributions through Weblate. The repository identifies its license as GPL-3.0, and the project invites support through Patreon, PayPal, or Liberapay.
