Following the iPhone 5 launch in Septiber, October was a month of opportunity for mobile app marketers.

The Fiksu Cost per Loyal User Index was $1.06, down seven cents or 6 percent, from Septiber’s $1.13. Significant increases in organic searches and app discovery – driven by the arrival of the iPhone 5 and users’ natural enthusiasm for downloading apps on new devices – pushed costs down and created a huge opportunity for mobile app marketers to very cost-efficiently acquire loyal users in October.

Meanwhile, the Fiksu App Store Competitive Index soared to 5.40 million daily downloads in October, a 33 percent increase from Septiber. The Index painted a similar picture following the availability of the iPhone 4S in October 2011, when traffic also surged by a proportional 29 percent, and continues the surge we saw developing at the end of Septiber.

Organic searches soared during the month, as users eagerly explored the App Store, enthusiastically searching for new apps to download on their new iPhones. So while cost for conversions were equal or higher during this time, the heighted period of organic, natural discovery drove down the cost to acquire and engage loyal users. Many savvy marketers wisely chose to ride this “organic wave,” improving user acquisition rates without substantially increasing their spending.

From the iPhone 5 launch, we noticed consumers appeared to be less frantic about updating their devices immediately, many choosing instead to wait several weeks to make the upgrade. Similarly, some sei to be taking more time to select and download new apps, instead of downloading many, all at once. This shift may lead to an even steadier, more sustained opportunity for mobile app marketers in the weeks – even months – following a major device launch.

With the 2012 holiday season underway, early data from Black Friday and Cyber Monday suggests that mobile commerce will have a giant impact on holiday sales – and that mobile apps will have a successful season overall. We’ll see how that plays out in our Noviber Indexes.

From the U.S. to China and everywhere in between, Apple appears to be "winning" around the world – big time. This week’s Fiksu Feed will focus on a variety of new industry studies, each predicting an explosive 2012 for the company.

In looking back at the year that was, GigaOm’s Erica Ogg remarks that 2011 was the “turning point” for mobile, with smartphones outselling desktop and laptop PCs for the first time.

For the last few months, we've closely followed consumer anticipation for the iPhone 4S – tracking its direct impact on both mobile app downloads and app marketing costs.

With the arrival of the new iPhone, October was the pivotal month, putting an end to months of industry speculation and mounting expectation, and validating many of our own predictions based on insights gleaned from our Fiksu for Mobile Apps platform.

iPhone anticipation strikes again!

Last month, our insights showed that a hiatus in iPhone sales (ahead of the much-rumored launch of the new iPhone) were directly tied to the drop in app downloads from Apple’s App Store.

Android continued to grab headlines this week with new industry data highlighting the platform’s growing popularity and market dominance. We’ll check this out, along with some other interesting new mobile studies, in today’s Fiksu Feed.

After hitting stores last Friday, it took just three days for consumers to snatch up 4 million iPhone 4S devices – an all-time mobile industry record. At the beginning of the week, Apple announced that 25 million people were already using its new operating system, iOS 5, and that more than 20 million had signed up for its iCloud service.

This week in mobile news, Apple’s new iPhone 4S delighted early adopters, while its iOS 5 received a mixed bag of reviews following the much-anticipated Wednesday launch. Meanwhile, Blackberry users across five continents fumed as a massive outage cut off access to email and Web services for several days. We’ll explore these stories, as well as interesting new industry data predicting Android’s ascendancy, in this week’s Fiksu Feed.
