iOS: Rather mature Android: Not as mature, but with some careful choice of libraries (effectively eschewing native libraries and sticking to Javascript implementations where possible) we had basically no issues. Tooling for Android isn't as nice as iOS in my opinion (specifically the simulator even with Intel's fancy extensions sucked compare to the iOS simulator), but because we lived mainly in Javascript-land this was rarely an issue. Debugged and tested on real Android devices (this is one thing that worked really nicely with little effort). This is a real production app for a software-as-a-service product, though it's getting a small controlled rollout to begin with. I'll be writing up a blog post or two on our experience, so keep an eye out on my website over the next few weeks/month or two -- I'm not expecting any issues though, as our beta testing has gone brilliantly :)
