A1 Task Pro is divided into lists.

You start with a list where you can add tasks. Once a new task is created or selected, this opens another list where you can then create sub-tasks. This process can continue to repeat, so that you can break down your tasks into small detailed pieces.

In ListView you get the most important information at once and you can mark tasks as complete directly.
Tasks are sorted by priority and in alphabetical order. First displayed are all open and then all completed tasks.

By pressing a list entry, it is selected and a new list with its sub tasks will be displayed.
