CalDAV TaskSync beta is a task management Android app developed by CalendarTaskContact Sync Mobile. This app is designed to fetch tasks and to-do lists from the user's CalDAV server and sync them to their Android device. The app is currently in beta version and is not feature-complete yet. However, additional sync protocols like pure WebDAV, FTP, HTTP will be added in future releases. The developer plans to release the app as open source after it has been considered sufficiently mature.

The app comes with features like managing tasks stored on CalDAV servers, displaying, creating, editing, and deleting complex recurring tasks, a unified task list, filtering and ordering of tasks, automatic CalDAV task storage detection, automatic and manual two-way sync, basic tablet and full phone UI, basic alarm handling, and a widget that can be used on the lock screen. The app is available in English, French, German, and Russian languages.

Please note that this is just a beta version, and the app might have some issues. The developer requests users to contact him at if they face any issues or if they have any ideas.

Overall, CalDAV TaskSync beta is a promising app for task management on Android devices, and we look forward to seeing its future improvements.
