The move to a Retina display in the latest iPad as well as the iPhone and now iPod Touch models has resulted in a noticeable jump in the average size of iOS apps in the last six months, reports ABI Research. Apps have seen an average 16 percent jump in size since March, when the third-generation iPad was unveiled. Games for iOS have grown even more, some 42 percent on average. While Apple anticipated the growth and increase over-the-air download limits to 50MB (up from 20MB previously), the increase cramps storage and bandwidth limits for many users.
