“Fiksu provides a Software Development Kit (SDK) that is used by a wide range of companies including 7 Eleven, Coca-Cola , Disney, Samsung and Zynga that helps them grow their user base. It measures each iPhone only once even if it is running multiple apps with its SDK so it can provide some insight into how well the various iPhone models are doing,” Chuck Jones reports for Forbes. “Fiksu has been monitoring the usage of its SDK on the iPhone 5c’s and 5s‘ that have it installed since their initial availability on September 20, 58 days ago.”

“It has found: The iPhone 5s represented 6.72% of all iPhones that were using Fiksu’s SDK. The iPhone 5c represented 2.59% of all iPhones,” Jones reports. “The 5s and 5c had a combined total of 9.31% of all iPhones. The iPhone 5 at the same point in time post-launch represented 5.54%.”

Jones reports, “To estimate how the 5c and 5s may be tracking compared to the 5 you can take the percentage that Fiksu’s SDK is showing up on the 5c and 5s (9.31%) and divide it by the 5’s (5.54%) to get a ratio of 1.68x or 68% higher. Since Fiksu’s measurements are calculated against the number of iPhones in use I believe you also need to take into account the larger install base of iPhones vs. a year ago.”
