Create and save checklists with reusable items. If you are looking for an app that saves your checklist items instead of deleting them as they are checked off, this is the app for you. When you add a new item to a list, the item will automatically be add to the Need list. When you check off an item in the Need list, the item will disappear from Need, but still be saved in All. Tap on the item in All to add it back to the Need list. Its that simple.
