Visual Math 4D App Reviews

I installed this app mainly for plotting complex functions. I wanted to have a better understanding of wave functions in quantum mechanics. However, there is no way to plot complex functions despite the app descriptions!

I used this app's export function for papers and lectures several years ago. I recently came back to it, to plot some practice error surfaces for adaptive filters. But now I can't find the "Save" button/menu to save the whole set of equations, not just the exporting plots. The export menu doesn't seem to have a Save item. I checked with the dev's website but couldn't find anything. Any help appreciated.

Wonderfully good graphs. And graphics!

Clearly many nice things about the calculator, but I couldn’t get it to plot a complex function using standard notation. Tried multiple plotting types, multiple ways of input. It’s either a limitation of the system or the documentation— either way there are too many competitors for me to continue spending effort trying to decode the limitations of the app. Pity — as this would be great for plotting wave equations. (It does work with sin/cos expressions — but I’d rather type my equations in b

Really great App. Awesome work here. I have a iPhone 4, not even 4s (slow processor) and it works Great! Highly recommend! 👍👍👍

OUTSTANDING. ..HOWDOYOUDOTHAT.* .XLOPTRADENETWORK.. H.Aparicio.

when you zoom , the app occasionally feeze .

I don't get this but it's fun to use

Unfortunately, this program no longer works on my iPhone 6 with IOS 8.1

The app won't open. I've tried it on both the iPhone and iPad versions. I think this is going to be amazing!

I wish I'd had this 50-years ago

Love ❤️ this app.. never thought it would be possible on my iPhone 👌🏻

How can I describe a math function like：x² + y² + z² = 4？

This app is useless. The calculator doesn’t work. The only thing you can graph are the saved functions... you cannot enter anything! Totally useless...

The best app I’ve ever met. I use it often

It’s an inspiring app, refreshing my math skills and learning new. But the Delete button is nicely hidden - takes a while to find out how to correct typing mistakes. How about a simple Backspace button in the Num block?

Muchas gracias es un magnífico programa

Good animation Would like to be able to save files where I can find them.

You never knew. - Heiroglyphics

Great 3D calculator to help you visualize. Does more than what it looks it can do. It'd be nice to have access to help/examples videos.

稍微不注意，点错一下就清除掉好不容易输入的方程，也没有历史记录。点击空白处还没法退出弹窗。

No instructions for using app. Interface is not intuitive. Doesn’t appear to graph functions that are user made. Handsome graphical display but limited usefulness. Nice app for what it does.

Went to ? (help) and noticed there isn't documentation. I thought this might help my son but even I’m having a hard time figuring out the basics. GUI is pretty cool.

The app does only exactly as advertised, you can’t even add a comma (,) to a vector field. Nor any i-hat j-hat k-hat etc. user input is feigned but always throws an error unless it is exceedingly rudimentary. And even so those even throw.
