Ratings and reviews

I needed to know how to solve ODEs for a class I am taking. Ive learned them before but had completely forgotten how solve them. I looked over several old textbooks I used for calculus, but without a professor I just couldnt figure it out what to do. As a last resort, before going to tutoring sessions, I decided to check this app out. The explanations were simple and detailed with several practice problems. Only gripe is that there were a couple tiny mistakes in the examples.

The app is excellent, but... there is some things that must be said. First of all: the contents are too short. And simple. Could not you guys improve this? Make the contents more detailed and didactic? Some, like Functions, deserve more details that can make easiar to understand. Second: more graphs, images and diagrams would be really good and fascinating. In addition, more examples, exercises, and solved exercises can help a lot in learning. But what really makes me uneasy is the fact you guys don't give the necessery information concerning the contents, what makes it incomplete and, in the most times, harder to get into the head. What I have noticed, on the other hand, is that all of this happen most in harder contents.

Excellent app with clear explanations. I love to see my classes explained in different ways to understand them better. I did notice some small typos, but nothing bothersome. However, one thing that I would like to bring to your attention is that some equations don't show when holding the phone vertically. I noticed it in the "integrals along a curve" chapter. I saw that in other places (e.g.: matrices) there was a scrollbar allowing me to view the whole thing.
