This application does work, but if you try playing a character that isn't recognized, the app crashes. For instance, try entering just the '+' character and click Play, and you get a crash. If you stick to basic letters and numbers, this app seems to work pretty well. I like the fact that it supports Farnsworth spacing, and the "save-to-WAV" functionality works for me.

Worked fine to generate the code for the words that I wanted to memorize, but crashed when I wanted to save the .wav file. Come on guys lets get it right!
