What is it?

Tasks is an app for Nextcloud, the self-hosted file and collaboration platform. It lets you create, edit and delete tasks in the browser, including titles, descriptions, start and due dates, priority and status. Tasks can be nested as subtasks, and you can drag them between calendars or into other tasks to reorganize them.

The app stores tasks as CalDAV calendar entries, so a range of third-party clients can sync with it. The project's supported list includes Apple Reminders, DAVx5 on Android, Thunderbird Lightning, GNOME Todo, vdirsyncer and several other iOS, Android, desktop and Linux apps. Smart collections group tasks into views for important, current and upcoming items.

The app is installed from the Nextcloud app store under the Organization category. Developers who want to work on it clone the repository into a Nextcloud apps directory and run make, which requires Node.js and npm.
