I was curious about the super lopsided iOS and Android numbers, as we were discussing these stats earlier in the office, and it seems like Android wouldn't be worth investing in based on these stats alone.

However, the iOS version was released over two years ago (March 24, 2011 on iPad and April 27, 2011 on iPhone) while the Android version was released in November 2012.

I was wondering if these numbers are standard, or is availability the main issue here? Or something else that I haven't thought of?
