SpeedList helps you keep track of tasks, items and anything else that can be put in a list. Create lists for food shopping, chores, vacation packing and tasks for work. Organize by creating sub-lists.
SpeedList is designed to be easy to use. Items can be quickly copied between lists with just a few taps. This ability makes it easy to have master lists. For example, a master food shopping list can be used to quickly create a secondary list for just those items that are needed today.
SpeedList also allows you to share lists by e-mailing them. Items can be automatically sorted alphabetically or by completion status. Work in portrait or landscape mode.
