App is good resource, not a teaching tool

The one star reviews are harsh, unyielding, and expect the app to be something it’s not. This app is a clean, spare, dictionary of math formulas and concepts. All the info in a clear, easy to find place.

It assumes you’ve already learned the material, and need help remembering it. If you are not learning or haven’t already learned the concepts, this will not teach you.

It is not a magic wand, it’s not a teacher, and it’s not going to make the math itself easier. It’s simply a library of information that’s easily accessible. Khan academy and other online tools are not this. They are online math lessons, this is not.

For the people complaining about the price, it’s $3, far less than the cost of any book. The people who built it did an excellent job, and you’re able to test the app out for free. You don’t pay the money unless you decide the app works for you. If the app is not what you need, that doesn’t make it a 1 star app. The rating of apps is not about you.

Not the best and probably not the worst

The app isn’t really what I would call “interactive” and it is overall very shallow. The UI is mediocre at best and it doesn’t really feel any different from any free app. Idk for me the sorting is weird since they show u a table of anti derivatives before you even learn about integrals and how they work. Focus on organizing the math by difficulty if you can since there’s just section headers. Sometimes people don’t understand certain variables and symbols; so it would probably be a good idea to put like a hoverable ui element over symbols or math terms people may have forgotten or are unaware of. Overall I’m not really impressed and to me there are much better options out there rather than paying $3ish for premium. I’m pretty sure this team of people are new to app development but I think they should know what happens when they slap a price tag on their software (if they don’t know already). As people said before, khan academy is free of charge and is much better than this currently is (yes khan academy has much more resources but still), and the developers should focus on a way to make this app teach math in a unique and engaging way.

Don’t Even Bother

I am a geometry student in middle school and I downloaded the app after seeing an article written about the developers show up in the App Store’s feed. Personally, I have always struggled with remembering theorems and laws and they portrayed it as a well put together app that could explain theorems thoroughly to help you better understand them. From most of what I have learned this year—not even half of our curriculum can be covered without paying. You would have to cough up some cash for some of the more important equations/laws/theorems that are crucial in a geometry or algebra class. This is including trigonometric laws, vertex formulas, factoring, roots, polygons, and many more. The theorems included are vaguely explained and are lacking in examples. As for the display—it isn’t beautifully designed, but isn’t horrendous to look at either. Although I will cut them some slack as this is their first time in the field of programming. But overall, if you are struggling in math and looking for an app that might help you—I invite you to look elsewhere. There are plenty of good websites out there including IXL or Khan Academy.
