This app is incredibly helpful to me. The textbook explanations for my Algebra 2/ Trig class are confusing at best. (Some of the things I mutter under my breath in class would make a sailor blush...) Seeing the work on the assigned problems instead of the simpler practice problems helps me understand the topics much better. The $7 charge didnt make me happy, but it was definitely worth it. My only complaint is that there is no offline mode. Aside from that, its a great tool to have.
