Apple, the platform that started the application craze, has recently fallen a close second to Android applications available from Google Play. Some of the other top mobile OS platforms were a bit slower to get into the application game, but they too have their own app stores where applications, games, ringtones, and more can be downloaded for free or for a cost.
As of the latest available statistics, Google Play still has the most available applications, hovering around 3 million,1 and Apple is a close second approximately 2 million available applications. Social networking and messaging applications remain the most common on the list of installed applications, and those applications that offer the user an ability to hide and permanently delete data are also rising.2
