In-app billing is something most iPhone users are familiar with already. iOS developers have long had the option of offering an app for free, or very little, with the opportunity of upping revenue via in-app purchases made by customers. Think purchasing new songs or levels for games like Tap Tap Revenge, or new editions of publications, like Sports Illustrated or Men’s Health. Now, Android developers can do the same.
Google this week announced that in-app billing had finally arrived in the Android Market. With it come a host of new apps that use the new feature, including Tap Tap Revenge by Disney Mobile; Comics by ComiXology; Gun Bros, Deer Hunter Challenge HD, and WSOP3 by Glu Mobile; and Dungeon Defenders: FW Deluxe by Trendy Entertainment. Aside from pushing new features for apps you already have, in-app purchases also offer a unique opportunity for try-before-you-buy.
