If you mean mobile apps, none, though I have gotten interested in writing some. CLI and very simple web apps (local cgi's), quite a few. GUI: nothing for real practical personal use, but a few to practice with the toolkits, and I've done commercial work with them.

I'm sad about the mobile app world. Lots of ridiculous bloated apps to do the same things that a very simple CLI or CGI script could do.
