I can easiy refer to this app. I mean, this app makes it difficult to not believe in a god, so, not recommended for tests for obvious reasons (cheating) but great as a study aid to learn how to do a problem.
Not only does it give you free answers, but it teaches you exactly how it got the answer, i don't know how much the premium is good but if the non premium is this much good then premium will be outstanding, loved using this to help me with math.
I recommend the premium version to help you learn. Solves all basic higher mathematical problems like evaluation of limits, integrals, derivatives, very good application, detailed steps many formulas quick and time saving, the GUI is very no nonsense, without many fluff features, really good app to help with math.
