Apple has made a small but significant change to app descriptions in the App Store: now the age recommendations are displayed prominently right beneath the app title when users search for apps. Previously, age ratings were listed at the bottom of the app detail page, making them hard to spot.
Apple has always prohibited apps with "adult" content from the App Store, but recently some social sharing apps have been capturing headlines when users post adult content. The change to the age recommendations may help Apple avoid some negative publicity, and it will definitely help parents make better choices about which apps their kids can use. For the mobile development industry, the age recommendations could also become more important, particularly for apps that are targeting a wide audience.
