I was wondering; is it hard to port a Android app to iPhone? Hold on, don't freak out. I do not develop at all. But if google let u use sketch up to build the graphics for apps in android, then you can make good graphics. Add some code you have a good app. If it's easy to port to iPhone, work is almost done and you have awesome graphics. then u don't have to buy other 3d engines like unity, you just use sketch up. anyone know if it's hard to port an app from android to iphone?
