It might not be as bad as you think. First, you've gotten the following you have based on reputation and your following so far. Second, most IT applications are written about more than they are talked about. I think consumer apps need a pronounceable name because people talking about them provides marketing value. But the discovery of most IT apps comes from written communication - blog posts, Google searches, etc.

Finally, if you're really concerned about it, maybe incorporate a pronunciation guide (phonetic symbols) into your branding somehow.
