Call me a cheater, I deserve it, especially for this post. Yes, this UI is made from plain, out of the box, Xamarin.Forms. Without looking at the code, can you tell how I did it?
Let me give you a hint. The UI is made of a CarouselPage, ContentPages, RelativeLayouts, StackLayouts, Images, Labels and nothing else. Still stumped? Well, the secret is in the sauce. Come on, I had to use that one!
