While I was in Austria, the iTunes store finally approved my first iPhone application. Hooray! Lothar has gone live and you can try it out here.
Now, even though it has iAd — which I included because I really want to see that Nissan LEAF commercial! — I've never once seen them appear when running the app, so it's pretty much free and without commercials for all who use it! Of course, I don't know if anyone besides me will be using it, but if you like it, feel free to drop me a comment. :)
