Lurpak's Good Food Finder app lists 3,500 stockists of good food, from butchers to delis - all recommended by their customers.

Now one of the biggest sources of local food finds in the UK, the app was driven by a Facebook and CRM campaign by the butter brand, encouraging food lovers to add their favorite food stores. Each Good Food Find lists the retailer's details, profile, location and customer comments, and users can also search for foods by category.
