Math Ref App Reviews

Very solid app, well made, has excellent information on a very wide array of topics from finance to physics to algebra. Everyone can find value in it.

Im a high school student in AP calculus and AP physics and this app never disappoints when I need a quick references. It has everything from basic algebra, unit circle, trig identities, to calc derivatives, integrals, series and much more. it also has a handy unit converter feature. Great work!

Very handy and helpful when working on math problems.

Great reference.

I look forward to the update that includes la Place and Fourier Transforms.

Just what I need. Comprehensive & highly useful. Thank you.

Very well done. Better than my ti84

This app is great! Its very well organized and easy to use.

I want to marry this app. It has EVERYTHING I need and more. Extremely organized, and often interactive!

This app has just about every formula that a Math/Science/Computer Science student ever need! I find that the formulas are quite useful for brushing up on my forgotten Math/Calculus/discrete.

A friend of mine recommended me to get this app, and my was this worth the investment! The developers deftly managed to condense the most essential of maths and physics into one convenient app. But, granted, I think the app needs a name change, in order for this app to not appear limiting. Before I bought this app, I thought there were only math related notes and such, but there physics things, financial doodads, pleasant surprises like the prime numbers and so much more. There are also other tidbits worth mentioning, like having a quadratic solver, a triangle solver, etc. That said, Id like some things to be added, or at least tweaked, like e.g. In the quadratic solver, the answer are given in decimals; itd be great if you added an option to express them in their full notation, as in 1/2 +sqrt(3)/2i. In the triangle solver, Id recommend an option to express angles in minutes and seconds as well. Just in case, check for some spelling or context errors, because I remember I spotted one in the financial section. One last thing I want to point out is what I disliked when you guys overhauled the app for iOS 7 was that everything was expanded out, in the sense of that the sections were like in this opened state displaying their content. It would be less of a hassle to list the sections, and make us tap them to reveal their contents, for the sake of organizing.

The recent changes are very good. What this app needs now is a formula editor so you can write your own theorems and handy formulas to keep them with you. Add that feature and i would gladly pay for it.

Ive only owned this app 15 minutes and already I am very impressed. I can tell that in my role as a modeling analyst I will call upon this application frequently! Well done!

Hello . I have bought great tips in this app but there is no change in my app.

I paid for pro and cant access the favorites I think its kinda messed up to sell a feature and then not have it work. I love the app its amazing but it needs an update and as others have said ability to input user formulas would be awesome but please fix the favorites!

Useful for grade school math through linear algebra / integral calculus. Great interface too. Love this app!

This is like carrying your linear algebra, geometry, trig, calc, differential equations, and matrix algebra textbooks in your pocket! If you can remember all those topics, their courses, and specific applications, then skip this app (

This was a decent app, but the new update wont load and freezes my iPhone, so I was forced to delete it. A little suspicious how long this app has been out and there are supposedly not enough reviews to calculate an average for a rating. You only need 2 numbers to make an average. Also, there are no reviews,...hmmm? If this review doesnt get posted, I will resort to blogging, along with screen shots. Dr. Lewis

Hi Dr.JEL, Full disclosure, this is the developer of the app. Sorry the app isnt loading for you and Id love to help with that. As for the reviews, they only show for the current version and since the app was just updated none show up. Really like to help you so I hope you can reply by emailing me at chris[at]happymaau[dot]com.

As a math teacher, I recommend this application to many students. I like the wide array of formulas present. Moreover I think the problem solvers are topnotch and offer help to most undergraduate students. I would recommend this app. thanks
