Well it's not my first post, but I made a new account for this project so technically....
I just wanted to put a post up about the iPhone/Android app I'm involved with.  it's a BJJ instructional called iBJJ, we've been working hard on it for the past year. 
A lot of the design and interface has evolved over the last year as we get feedback from BJJ students using it. At this point, it has a lot of unique features that no other apps have.  We have about 70-80 moves in there now and are continuing to add more to it.  We will also be releasing a "Wrestling for Jiu-Jitsu" module shortly that will integrate into the app.
I kept the moves pretty basic to start off so beginners could get a lot out of it, but i tried to put a lot of key details in the moves as we broke them down so it would be of use to a variety of different levels.
If you want to check it out we are at www.paxmow.com.  If you already have it and have any feedback please let us know what your thoughts are or any input you may have.
Thanks for all the support!
Nate
