Chitika says iOS 7 adoption rate hits 89.7% for the Apple iPhone, 84.8% for the Apple iPad58
The current North American adoption rates for the iPhone trail what we saw for iOS 6 last year, just before WWDC. At that point in time, iOS 6 was on 92.8% of Apple iPhone units. At the same time, 82.9% of Apple iPad users were running iOS 6.
Chitika blames some issues that users are having with iOS 7.x, as the reason why the adoption rate for the iPhone is lower this year. The higher reading for the iPad could be due to the fact that iOS 7 is supported by all iPad models, except for the original generation slab that launched the category in 2010.
Chitika also noticed that the percentage of North American based iPads running iOS 5 or earlier, is 7%. On the iPhone, that figure is only 1.5%. Chitika blames this discrepancy on the perception that there are more features for the Apple iPhone than for the Apple iPad, on the later versions of the OS.
Chitika's data came from analyzing tens of millions of U.S. and Canadian iOS based ad impressions.
