calculus solver
It is a little buggy sometimes, but overall it is one of my favorite calculus apps. It will show each individual step to solving a problem as a side show which I really appreciate, can be very helpful. The keyboard could use a little work, but it is significantly better than Wolfram Alphas. Overall I Highly recommend it to any calculus student.
