[racket] Racket equivalent to RubyMotion

I'm writing in Racket, after months of Scala, which was nice too, in a different way.  Today I found out about RubyMotion, and wondered how hard it would be to do do the same thing in Racket, i.e., write iOS apps in Racket, and write Android apps in Racket.  In know I can write Android apps in Scala.  I don't remember if there's a Racket way to do that.
