I don't know about V.P. tutorial apps but I do know that Bob Dancer in his book "Video Poker For The Intelligent Beginner" said that he would not be making anything like one because it is illegal (at least in the state of Nevada) to use such a thing in a casino. And so since there is the possibility that someone might take it into a casino and use it, he wanted nothing to do with that.
Actually, if I'm remembering correctly from reading somewhere here, there may be an App by Dean Zamzow who actually programmed the WinPoker computer program.
