Great app for calculus

Im taking calculus right now and Ive got to say that this is by far the best calculus app on the App Store. It is very thorough and precise yet the content is packaged in a way that makes it approachable and easier to learn than in my lectures. I highly recommend this app it is definitely worth five dollars!
