Just as there were lots of iPhone-only apps when the iPad was first released, but they are uncommon now. The point being that it isn't an Android thing or an iOS thing, both OSs allow developers to produce apps that run at different screen sizes and aspect ratios, but it is up to the developers to actually code that support.
Androminium was one I remember, it just got a proper tablet UI update last month.
