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.

(defun write-tag (tag string)
  (if (null tag)
      ""
      (format nil "[~a]~a[/~a]" tag string tag)))
(defun bb-buttsort (s)
  (write-tag "i"
   (write-tag "b"
    (apply #'concatenate 'string
       (loop for c across s
          and parity = nil then (not parity)
          collect (write-tag (if parity "o" "u") c))))))
