Re: iBudokan: Aikido App for iPhone and iPad
I have several of them, and they are awesome. :-)
I only played with them a little when I first bought them, but as I recall then it was hard to know in which app to find which technique. The "All" version is out now, and that's the next one I'm going to get, so there's no guessing about where to look.
Very valuable, fun resource, and well produced. I highly recommend it!
