I was kind of dissapointed that there's no Hiragana Learning Programm for Windows Mobile. So I sat down and hacked an extremely simple program. It's multiple-choice with 4 other choices. Your progress is stored in a text-file and the likelihood for a hiragana to be questioned depends on your "wrong/right"-ratio.

As mentioned it is extremely simple. If I stay motivated, I might add katakana and some other options like adjustable number of multiple-choices and choice of subsets of all hiragana.

The app needs the msgothic-font to be installed. I uploaded a cab which does exactly this.
