Six stars if I could, The range of positions and transitions are great and there are some hidden gem submissions here as well.

This app is amazing for those who know their jiu jitsu game. It's hard to find a well educational app for the sport, but this app is that one in a million. The rest just try to sell me all their crap, unlike this one. Thank you professor Monterio! Oss!!!!

Professor Marcello MONTEIRO is a high level BJJ black belt and one of the best coaches in the United States. He is the most knowledgeable instructor I have even been taught by! Apps are worth it!!!!
