Android/iOS simultaneous development in LISP

I want to make a program for both the Android and iOS, but I refuse to learn disgusting languages such as Java and C#.

Currently I am a [b][i]C expert programmer[/b][/i] and know a little of Common Lisp and Scheme.

So, is there a way to develop for those two mobile OSes trough a good language?

I believe Clojure may be an option? But I'm not quite sure, never worked on something outside my computer. And I am only expert at C.

And I am only expert at C.
Use Common Lisp, it is:
1. portable
2. uses mostly functions, like C
3. runs at 1/2 speed of C/C++ - i.e. fast enough, for smartphones
