Keep working on this cause you're doing a good job. You can make it much better and also improve the latex rendering speed. The JS is too slow or something. Also you're missing a lot of basic materials that Khan Academy has. I hope you add more stuff. If you do an incredibly comprehensive enough job covering *all* of basic maths then you will be rewarded.

You should definitely cover series since you already did sequences. Also, you can't stop dividing because the quotient is less than the divisor like you did in the prime numbers part. If the number were 156 instead of 157 you would have stopped too soon and the result would have been false. If that's not what you meant, the text certainly seemed to infer that. Great app tho :)

Hey, it's been such an amazing app so far! I think I have detected an error in the matrices section, specifically in the sum of matrices fourth LaTeX square, you are adding 0 + 1 and the result is 2 (?) I wish I was able to upload and image, but I don't seem to be able to at all. Hope this helps to fix the issue!! Keep it up, best math app so far!!!!!!!!

Honestly, this is a simple and elegant app. I simply loved the design and the depth of the explanations given in each topic, not too much, not too little. The only complaint?, put a donation link in the app so we can donate via PayPal or something. Great job, I'll review it on my YouTube channel!

Don't understand the high reviews. This is Ok for revision of what you know, but not for learning. You can go from ultra basic 'what is a line' to complex calculus in a few clicks without much of the intermediate stuff being explained. Sometimes new notation is introduced without being explained. I don't think this app has a clear target audience. Khan academy is much better.

M70%

Pretty neat, but I found a mistake. In Calculation of limits, 0/infinity isn't indeterminate. I now think there might be more mistakes, so I'm cautious with this app. So far, everything makes sense except for that.

Really nice app, have only had it a few days but it seems very well done. One thing that would be really useful would be an offline mode as it won't work without a data connection.

T70%
by T####:

Very good and easy to understand, but be careful. There are typos here and there with some examples that leads to confusion. For instance, the summing matrices, the fourth sample the result matrix says 0 + 1 = 2

This summer, I'm finally allowing myself to understand mathematics, and this, over any other app has helped with the "theory" of things, rather than the straight away practice of concepts as other math apps do. However, I'd for there to be a way for people to interactively quiz themselves after the theory, so that this could be the perfect theory + application app. All in all, helpful, educational and pleasantly not money based : )

Really good and covers a lot of in depth math material ranging from beginner to intermediate. Latex formatting runs off the side in some pages. I Would like to help out. Let me know.

An extremely well implemented app. The UI and functionalities are clean and to the point. Using this app is a joy. Suggestions: 1. Try to decrease the loading time per page. Try caching the pages locally so that they can be retrieved faster. 2. Introduce a way to navigate between different chapters of a module without having to return back to the list of chapters. So that the user can read the various chapters of a module in a continuous flow.

This app requires an internet connection to run whenever it is opened. This is a big problem for me. Why is it this app cannot run without internet access? If this is changed then I'd give it top rating

P70%
by P####:

Transition between pages feels a bit laggy. However, overall good. All materials packed concisely. It helps me to get clarity in some concepts. Thank you.

P70%
by P####:

Looks nice, but the language used is very confusing and in some cases, grammatically incorrect, making it difficult to read. Having said that, the layout, look and feel of the application is very nice.

Come isn't agree with Paul's review below more. This app is strange, inconsistent, and shouldn't be used for learning. Use Khan academy. Thorough, organized, consistent, and easy to understand.

J70%
by J####:

There's no ability to send feedback in app, so I'll put it here; Sum of matrices, example 4, the fourth element should add to 1, not 2

T70%

There are several typos that make reading pretty confusing, but the contents are very informative. Please sort out writing inconsistencies

This app is so much great, but there's just a problem, sometimes the example come out of screen and you can't see it completely, but it's just few of them. Nice app.

This is the best mathematics App in the world it covers all level i have to delete all other maths App on My cell phone for this.... I love you developer this is what i have been looking for... But pls try make it offline

S70%
by S####:

This is brilliant. Great content. But it will be 5+ * if this includes quiz right after the chapter. Hope to see quiz feature added!

stuck on loading screen of a chapter. Back button won't work. Except contents it's not a well developed app.

It is rich in content and with superb explanation i love it, thank you so much because you build this superb app for us and i believed that you done much better and better... All the best...

Really nice and well organized! It has everything you may need to review and it's very easy to understand!

Due to an application error. If you use Phonegap, this is a phonegap bug, else workaround this.

F70%
by F####:

That's a great app! Very useful to refresh my memories during my commute! It would be good to have a check box to activate when one is finished to read a page, so one can keep track of their progress.

If you don't cover p-adic numbers, I'll write you a poorly worded letter.

"☹️ We are sorry, there has been an error connecting to our server" every single time. Uninstalled.

I love the simplicity that's been used and I'm learning a lot, thank you!

F70%

This is app is brilliant. Just a suggestion, add an offline feature where user can save a topic offline for future reading.

T70%
by T####:

Take this points in consideration: -add videos for every topic -problems to solve and practice -improve rendering speed

Good. There's a small mistake in sum of matrices. The 4th image or whatever you call it

It's taking a lot of time to open & I don't have that much patience

L70%

That's what I needed to review general topics without having a huge book or even a laptop. Found a couple of errors, but the idea is amazing. Thanks for it!!!

Didn't cover enough but the idea was good.

C70%

Absolutely brilliant. The writing is clear and reasoning is easy to follow. Would love to see more concepts introduced later on.

The app contains a huge amount of topics and the explanations are very well written! :) Thank you for developing this app, and keep up the good work!

Very good content One suggestion if you could incorporate: Instead of seen "eye" notifier, have a "completed" checkmark which has to be done manually etc

T70%
by T####:

I give it 5 stars! I love the attention to detail put into each subject. Can we get a search feature for it though?

H70%
by H####:

Useful app, but can it have offline option, like you can download specific content.

Great app I use it in college for math and it is very helpful and useful for me. Thank you.
