Instagram is fun because it feels a bit like sending mobile postcards and, the app’s ubiquity notwithstanding, a billion-dollar company is nothing to shake a stick at. Building on this theme comes a new app from House Industries: Photolettering. The app, which has access to House Industries’ renowned library of fonts, lets users create and edit their images with various typefaces. Like other mobile photo apps, Photolettering prompts users to take, scale, crop and rotate photos. Perhaps the most integral function of all, users can also share their creations with their friends. With the popularity of these kinds of applications, all the possibilities for growth, and improved camera phone quality, could Photolettering be the next big thing? Only time will tell. Until then, have fun with the app, which is available for free from the iTunes App Store.
