Surely the demographic fault lines don’t line up perfectly, but the evidence is pretty compelling that iOS users are a different sort of consumer than Android users. On a related note, something else that crossed my radar this morning was an article over at Business Insider about T-Mobile’s decision to change their network architecture to allow the iPhone. “T-Mobile, which was the first partner of Android, thinks that it needs the iPhone to be sustainably competitive.” (Full disclosure: I know this is one reason Giant switched away from T-Mobile in 2011.) How does this impact second screen and companion app developers? Certainly it means that iOS is a ‘must have’, but Android may be part of a ‘belt & suspenders’ approach. If you want to cover the greatest segment of tech-savvy mobile consumers, do both. But if you’re dipping your strategic toe in the mobile app/second screen world, it may make sense to begin with iOS and expand after the technical and marketing kinks are worked out. We’ve had a number of conversations with clients and potential clients in the past 12 months about this very question and I believe it’s definitely an idea you’ll want to keep in mind as you formulate your app development plan.
