Great app for learning about learning the fundamentals of mathematics. However, I would suggest putting an "About Us" section, the citation and links for the sources used, and exercises or some sort of feedback mechanism to remember and make sure that the user understood the concepts. Also, it would be really great to have a dark mode for us readers in the dark.

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.

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.

This app is incredible for learning, the app do not have too much content but its a good start point for learning the topic you are looking for, in my case, Linear Algebra. The app have different languages, including spanish, that's nice for me, and you can change the language in one second if you want to learn in English.

Amazing app. Topics are concise, but effective. Besides small typos, I have only one thing to criticise. That is lack of order in the topics of individual section. The experience would be much more pleasant, if you didn't need to constantly jump through topics to understand the concepts. But that's probably too much to ask for, so I would suggest at least improving the favorite/view tab by making the topics there shown in the order they were added.

Good at explaining particular concepts in maths. But if you're using it as a resource to learn maths it could be slightly improved. For example, one of the first topics is about calculating the rank of the matrix using determinants, but the method of calculating a determinant is used without an explanation of what determinants are. A later topic in a different subsection is about the calculation of determinants, but ideally this should come before the use of it or there should be a link to it

The app is great 👍. The only thing is that the topics are unordered so some time it's hard to know where to start from when you just want to learn. And for that you need to rely on google which than becomes time consuming. I hope you can atleast add a order of the topics.🤗

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.
