MUMBAI: Fiksu, Inc., the industry's first mobile app user acquisition platform spanning the entire mobile ecosystem, reported that the swell of new iPhone 4S users, combined with iOS 5 app updates, generated escalated app discovery activity and peak download volumes for the top 200 apps.

The Fiksu App Store Competitive Index (which measures the average aggregate daily download volume of the top 200 free U.S. iPhone apps) continued its upward trajectory initiated during October when the iPhone 4S launched. The Index peaked at 5.65 million downloads per day in November; a 15 percent increase over October's previous record high of 4.91 million daily downloads. By comparison, app download volumes in November 2010 were 83 percent lower, illustrating the enormous demand for and growth of mobile apps in just twelve months.

The Fiksu Cost per Loyal User Index remained steady in November, down just four cents to $1.43 from October's $1.47.

"Unlike October's intermittent spikes in downloads and costs, November saw a steady increase in demand for app downloads without any notable fluctuations in mobile app marketing costs - even over Thanksgiving weekend," said Micah Adler, Fiksu's CEO. "Signs indicate that app marketers have become savvier about planning and executing their ad spends during seasonal periods to avoid paying premium prices for acquiring users. In fact, November presented them with a somewhat unique opportunity to add more users at costs that were actually below October's."

The Fiksu Indexes measure monthly fluctuations in competition for rank in the app stores, and the cost to acquire loyal users(1), helping mobile app marketers benchmark their performance against industry averages.

Data for the Fiksu Indexes was sourced from more than 7.6 billion mobile app actions - such as app launches, registrations and in-app purchases - and more than 156 million downloads recorded by apps marketed via the Fiksu for Mobile Apps user acquisition platform.
