OpenTasks is a free task management application available on the Android platform. Developed by dmfs GmbH, this open-source app is designed to provide users with a user-friendly interface for managing their daily tasks.

The app supports basic task management and provides a simple and intuitive user interface. Completing a task is just a matter of holding it for a moment and flinging it from left to right in the list view. Editing a task is also easy, just fling it from right to left.

However, it is important to note that OpenTasks does not yet support recurring tasks. While recurring tasks are visible, users cannot edit single instances. Any changes made will apply to the entire series.

OpenTasks is optimized for Android 4.x but works with Android 2.x as well. The app is open source and the developers welcome contributions. Users can report bugs using the bug tracker provided on GitHub.

The app is still under development, and the developers plan to add more features such as support for recurring tasks, alarms, categories, sortings, filters, and more translations.

In summary, OpenTasks is an efficient task management app that provides a simple and intuitive user interface. The app is open source, and the developers welcome contributions and bug reports.
