Great visuals, poor usability

I have a thing for great looking apps, and it fills a functional void. It has great aesthetics, but that seemed to take too much focus, and almost took it too far in simplifying.

Im not a fan with how the currency selection works. It should allow me to choose two currencies independent of one another. The current method is extremely frustrating.

Id also like to see a clear button. I like the swipe to clear, as its rather unique, but I would like the speed of a single tap to clear my values.

Hopefully this is constructive enough feedback!
