An app is aiming to get shoppers to work together to help each other get a better deal on their groceries. Sumfood has launched FoodSpies, which will compare prices between supermarkets on different food items using crowd sourced information. Founder Helen Darling says it will be easy for users to participate, because they'll calculate prices based on simple data. "What we do is, we actually take the aggregate number. All we want to know is the total price you spent, how many day you're shopping for and for how many people. And from that you can calculate an average per person, per price for different supermarkets." LISTEN ABOVESee omnystudio.com/listener for privacy information.
