How to make iPhone Apps and Influence People Musings on the iPhone development process

Recent iOS Version statistics from Delhi City Metro

Not long after iOS 4.0 was released I pushed a small update to Delhi City Metro to keep track of some basic (anonymous) user statistics. I'm keen to gauge the audience of any specific iOS 4 features I might consider adding and now that I've been able to visualise these, I thought I'd share them here.

To add a geographic angle to the iOS usage statistics you can see in the second graph that the majority of Delhi City Metro users are from India.

Several weeks after the launch of iOS4 the split between iOS 4 and iOS 3 is 4.x 64% and 3.1.x 31% with iOS 3.2 at 4%. (Delhi iOS Statistics 13-26/8/2010)
