Practice Self Defense Anytime, Anywhere With Self Defense for All
This is why we have Self Defense for All, courtesy of YawaraJitsu. This "interactive self-defense course" sticks to the basics with a chronicle of many different techniques to learn. Each one also includes 3D video (featuring models with MASSIVE HANDS) that can be viewed from multiple angles to help users to fully understand the motions.
I want to stress that I don't believe this app will truly teach anyone to be a self defense master. Something like that requires a senei with years of experience to point out inconsistencies in forms and other students to toss around so as to get an idea for what the moves actually feel like. But I do think it's a useful tool for students that want to keep practicing off the mat. Self Defense for All is available on the App store right now in English, Spanish and Dutch for $5.99.
