The Coca-Cola Freestyle app, created by digital marketing agency 360i, lets you mix a drink using 125 Coke beverages, including Coca-Cola, Sprite, Fanta and Powerade. After choosing each, you hold down a "push" button to fill a cup of your choosing. When you fill your cup, you can name it. There's also a game designed for the iPhone [iTunes link] and Android formats.
The Facebook Page also directs you to Freestyle vending machines in your area and lets you ask for one in your town. There are now about 1,500 such machines in restaurants like Wendy's, Burger King and Five Guys, but Coke plans to make more noise about Freestyle next year. The company is working with ad agency Ogilvy & Mather on a 2012 ad campaign for Freestyle, according to Advertising Age. Coke would like the apps to eventually generate a 2-D barcode, which could be scanned at one of the machines to create a blend, according to Ad Age.
