iOS 7 adoption rate after one day is higher than for earlier versions of iOS

If it seemed like everyone on planet Earth was trying to install iOS 7 at the same you were, well, you're probably not wrong in that assumption. Information from Chitika Insights and others who have been following the action of the past 24 hours shows that anywhere from 18.2 percent (Chitika) to 36.10 percent (Mixpanel at 10:30 AM PT, see figure below) of all iOS devices are now running Apple's latest mobile OS.

Why the difference in the numbers? Well, it probably has to do with the methodologies used by the two companies. A Mixpanel spokesperson responded to this question as follows:

The data in the iOS 7 adoption report on Mixpanel Trends is based on an aggregated set of the more than 15 billion actions analyzed by Mixpanel each month. The report shows the share of total activity on devices running a version of iOS at a given time, not on unique devices. In Mixpanel, an action is defined by our customers and can be anything from logging in to an app to making a purchase or finishing a level in a game.

I'm not familiar with their (Ed: Chitika's) methodology, so it's hard for me to speculate on why they are so different. But part of the answer could be the time at which the data was pulled. The data in our iOS 7 adoption report is updating in real time, so that 36 percent is as of 10 AM PT. Our chart shows we saw 18 percent adoption at around 5 PM PT last night.

Also, here are some other points you might find interesting:

  • In the first 24 hours activity on devices running iOS 7 skyrocketed, reaching 36 percent at 10 AM on Thursday.
    • People updated during the work day: Just 10 hours after it was released, devices running iOS 7 accounted for 22 percent of total iOS activity.
    • People stayed up late to update: Between 10 PM - 8 AM PT, iOS 7 claimed another 10 percent+ of activity.
    • At 9 AM yesterday, iOS 6 accounted for 94 percent of iOS activity. At 9 AM today, it had dropped to account for only 61 percent of activity.
    • If it continues at this rate, there will be more activity on iOS 7 than on iOS 6 in another 24 hours.
  • Compare that to Android where, as of yesterday and 450 days after launch, all versions of Jelly Bean account for 57 percent of activity according to the Android OS Versions report on Mixpanel Trends here. Android's official stats (here) have Jelly Bean adoption at an even lower 45 percent.

  • But the most recent version of Jelly Bean (4.2.X) only accounted for 12 percent of activity according to the Android OS Versions report on Mixpanel Trends here. Android's official stats (here) have Jelly Bean 4.2.X adoption at an even lower 8.5 percent. Compare that to iOS 7 which accounted for 11 percent of activity only two hours after release.

Chitika's spokesperson provided the following clarification:

While we can't speak to Mixpanel's methodology, here's how we tabulate our statistics for the iOS 7 study:

We examine traffic across 300,000 different websites within our ad network ---these range from several sites in the Alexa Top 10 to smaller blogs. Additionally, our network of sites comprises a wide variety of verticals (e.g., automotive, photography, retail, etc.) For this particular study, we examined tens of millions of online ad impressions to tabulate our results. An important distinction is that we examine web browsing activity, rather than in-app activity.

In comparison to the Android operating system, where only 45 percent of all devices are currently running Android 4.3 "Jelly Bean" -- an operating system that was released in July 2012 -- the adoption rate for iOS 7 is incredible, even when Chitika's lower numbers are used for comparison.
