Mobclix ran an infographic back in January 2011. The awesome thing it still holds water in this ever changing mobile environment.
With no surprise, to "people-in-the-know," we see that iOS' monthly app user base is worth more than Android.
This begs the question, why is this the case?
So I thought I would lend my two cents on "why"and see if you have any additional thoughts. I believe when comparing Apple vs Android the app ecosystem of both platforms are completely different, thus the users are completely different.
This is not by accident, but rather by design. Where Apple ask for a credit card upfront with a creation of an iTunes account, Google just requires you to open, or use, a free Gmail account.
Note: When we mention "free" in referring to Google, let me emphasis that everything Google does comes with a price. In this case "Free" simply means, "view ads."
