About Stuff I Need
Originally conceived as a grocery list app, this minimalistic checklist can be used to keep track of the stuff you need to get, or the stuff that you need to do. Items on the list can be edited (or deleted) by giving them a long press.
Lists can be switched by pulling down on the tab at the top of the screen. This will expose a spinner that shows all of your current lists. New lists can be added by using the “+” button on the right side of the tab. Long pressing on the list name, will allow you to rename a list. Any lists with zero items will be automatically deleted once you exit the app. By default you are limited to just two lists, but you can get unlimited lists with a $1.99 in-app purchase.
