I'm making an app so I can learn how to do video playback and how to use UITableView. One of the first things a new student of Japanese does is learning katakana characters. I have a video for each character that we shot a year ago. Those videos have been used on Japan Name on Facebook and also in the Japan Name iPhone app. Now I'm going to use them the third time and bundle them into a simple app that lists each character and lets you view the videos for each. I imagine this might be used by some students as reference. I can probably charge a bit more for this, so I'll try the next tier of $1.99 on it. If it sells a copy a week, that would be fine.
Update: Submitted it to App Store today!
