I think it increasingly means you have to be on both iOS and Android as soon as you can. I have advocated for building for Android first and iOS second. I think that strategy will start making more and more sense for apps that aren’t looking to be paid.
Step 1) Take VC money;
Step 2) Burn through that money making a free Android app;
Step 3) Get acquired (“acqui-hired”) for a few million by Google or FB.
No use in making consumers pay for apps when you can have VCs pay instead.
