“The App Store Competitive Index tracks the aggregate volume of downloads per day achieved by the Top 200 ranked free iPhone apps in the U.S. In November, the Index reached its all-time high at 5.65 million downloads per day, beating October’s previous record high of 4.91 million daily downloads – a 15 percent increase and the first time the Index has topped the five million mark,” Fiksu reports. “The launch of the iPhone 4S continues to impact the world of mobile advertisers. Compared to October’s dizzying fluctuations before, during and after the new device’s mid-month launch, November presented a far steadier landscape.”

“As expected, and as we’ve seen before with new device launches, new owners’ enthusiasm is high and their appetite for app discovery and engagement is strong. This bears out in the numbers with daily app downloads hitting a new, all-time record peak reflecting heightened competition for rank in the Apple App Store. Additionally, the rapid adoption of iOS 5 – and corresponding app updates – played a key role in this continued escalation in November,” Fiksu reports. “Comparing this November to a year ago, it’s remarkable to note that app download volumes have increased by an impressive 83 percent, highlighting the colossal expansion of mobile apps in just twelve months.”
