Organize your move with MoveHelper.
MoveHelper already provides an initial set of tasks. The list can be extended and tasks can be removed.
Each task has a status, date, a priority, and some place for notes. First, choose a date for a task, indicating when it is due. Then set the status to "done" whenever a task has been finished. If any task takes several days, it can be marked with the status "in progress".
Very important tasks can be marked with a higher priority ("Prio A"). To avoid to loose track of any task, just sort the list by priority, date, state, or name.
You can also export the list into an XML file for backup. If you edit an exported list with another android phone, and the re-import it, a merge editor shows all differences.
