550,000 activations per day for the green robot. It also could be due to the recent update to the Android version of the app which includes the Timeline feature, something that is currently missing on the iPhone's Facebook app. Until the feature is added to the App Store app,some iPhone users might decide to use the HTML5 powered mobile site from their Safari browser. Another reason for Android overtaking Apple in daily Facebook readers is that since the Apple iPad received its own Facebook app in October it now has 5.5 million average daily users, with some of those coming over to the iPad app from the unoptimized iPhone version and others switching from unofficial third party apps.
The numbers show that when it comes to monthly viewers, the Facebook app for the Apple iPhone gets 99.1 million average users against the Android figure of 85.4 million. But the monthly stats do not have the weight that "stickiness" does. This is the number of monthly viewers that return to the site every day. With the Android figure at 68.2% versus 57.9% for the Apple iPhone, that explains why Android has the lead in daily readers of its Facebook app even though it trails iPhone viewers on a monthly basis.
Why does this matter? These numbers are important because they could play a part in determining where Facebook and other developers decide to put new features and apps first. And if more features like Timeline are written into Android apps before the iPhone gets them, that could help phone buyers make a choice about which platform to buy. As far as the competition is concerned, BlackBerry's Facebook app gets 29.9 million average daily users while Windows Phone's app reaches 360,000 people a day on average.
