We have published our first web app: the ListMaker which allows users to log the items in their fridge after every shop. Then whenever, you eat something from the fridge (or food cupboards) you just have to remove it from your virtual fridge too.
By the time you go out shopping again, it will have automatically created the list of things that you’ve run out of and need buy while out shopping for your groceries. Now you don’t have to remember everything in your fridge yourself!
