Google’s announced that Android developers will be able to assign ratings (such as those used for movies, music, and video games) to applications to allow users to find apps more suitable for them. The ratings are All, Pre-Teen, Teen, and Mature. Every new application uploaded to the Android market will require the developer to set a rating starting next week, while existing applications will default to Mature if the party responsible doesn’t update their listing within a few weeks. This is just one of many Market improvements we expect over the next few months as Google continues to help improve the ecosystem.
