Hi, I've recently developed an app for my school in the iOS platform. Now, I want to expand to another platform. I know that Blackberry would seem like the illogical choice because of its declining market share, but believe it or not, Blackberry users and iOS users are a majority in my school, with Android users being the minority (I know, crazy!). Now, my question is, after developing for the iOS platform, which is easier to move on to? Blackberry OS or Android OS?
