As an investor in companies building mobile apps, I get asked this question constantly.

My response depends somewhat on the application and the market, but it's pretty clear at this point that these are two completely separate efforts. It's not quite as bad as developing for Mac vs. Windows, but close (and getting closer all the time.)

So I recommend two separate development efforts. I almost always recommend leading with iOS, but not syncing up the functionality perfectly so that some of the design experiments as you iterate happen on Android.

Tight communication between two separate teams is key. If you only have one dev working on the whole thing, just choose one - and - in most cases, this should be iOS
