Shortly after it was released, the Facebook for iPhone app was named the number 1 free app of all time by Apple Inc. That was in April of 2009. Since then, Apple has reported that around 1 million users download the free application each month.
Famous for their fastidious record-keeping, Facebook has also kept a close eye on their most popular app. They now report that over 15 million users have downloaded the application, and that nearly half of their mobile members use it to access Facebook on a daily basis.
What do free Facebook apps offer? Believe it or not, the first Facebook apps were an unmitigated failure. Most members complained that they were difficult to use and that they lacked many important features. But Apple listened to these concerns and introduced a new and improved version about a year later.
As we have seen, this new generation of Facebook applications has been a huge success. Not only are they much easier to use, but they also offer many of the same features of the standard computer account.
Far less popular, but still significant, Facebook apps are also available on Blackberry. According to the company, their top application is Facebook's Blackberry sports, which has about 10 million active users. Facebook apps are also quite popular on the rapidly growing Android phone.
