I'm sure they'll tell you that you can do this using Xamarin.Forms but we quickly realized that it is only useful for very basic UI. Anything of more than trivial complexity is going to require that you learn the platform specific frameworks and idioms (on top of learning Xamarin). At this point I have no idea if Xamarin is going to save time or cost time over going native. My guess is that it will depend on how much domain logic you can share between platforms.
