We read this article on VentureBeat and that 62,965 total apps number just didn't sound right... so we dug into the data and found the total number of apps appearing in the US app store is 55,977 as of about 3pm this afternoon.
Dean Takahashi, author of the VentureBeat article, based his number on Mobclix data. The Mobclix reports can be misleading because they don't filter for uniqueness. Some apps appear in multiple categories: a single app can appear in the Entertainment category AND in the Action sub-genre of Games, for example.
Games are special in this regard. There are no cases of an app that's not classified as a game being in more than one category. For our purposes we only count apps as "Games" if they do not appear in another
non-game category. There are roughly 3,000 apps in this overlap area, which leaves 10,175 apps that are exclusively categorized as games.
So, about 56,000 apps and somewhere between
10,000 and 13,000 of them are games (depending on how you count). This graph will give you an idea of the growth rate for the different segments, showing the number of unique apps each day for past month.
Special bonus feature! The total price of apps over that same time period.
