I'm looking for a price book app to help me with grocery shopping that works something like this:
You can enter the item (e.g. Apples), the price (e.g. £1.50), the package size (6 apples), the store (optional) and the date (optional). Then it computes the price-per-unit (per apple or per 100g). Then every time you search for "apples" it gives you the average price and the best price.
Any ideas? I'd be happy to pay for an app if it's highly recommended.
