The ACCC recommended that all supermarkets provide unit pricing for goods that would allow consumers to compare the price per unit for, say, toilet paper, to the price per 4, 6, 8 or 12 pack. I’m not sure what happened to that policy but in the meantime an iPhone app has appeared that does just that.
Apples2Oranges lets you enter information and compare prices. It is a few clicks less than using a calculator but it looks like it has lots of functionality.
It employs a simple touch interface where you can compare two kinds of modes: Ingredients Mode and Price Mode. Ingredients Mode lets you compare nutritional content for food you are eating or buying. Price Mode lets you compare two products side-by-side for the best price considering different measurements for volume, length, or area.
Basically, it is moving along the lines I had hoped for some months ago. A supermarket revolution is just beginning.
