### 5/5 — App review;

*2026-03-14*

Very useful; beautiful renderings;

### 5/5 — Eh.

*2026-02-08, version 5.3*

Eh.

### 2/5 — APP CRASHES/LOST EVERYTHING

*2024-05-09, version 5.3*

I was using this app for hours and hours every day for 3D modeling geometry mockups at work up until 04/01/2024. The app no longer opens, and I seem to have lost hundreds of saved graphs. Anyone else having this problem?

### 5/5 — Still one of the best, but one question

*2023-03-15*

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.

**Developer response:** Hello,
could you reinstall the app and restart it.
Which device and iOS-Version you are using?
The newest update needs iOS 11.

Regards
Ronny

### 5/5 — Spitze!

*2022-11-17*

1a App - stark! Intuitiv und schöne Grafiken! Vielen Dank! Dr. Hinner EDV, München

### 5/5 — Great Graphs!

*2022-08-19, version 5.3*

Wonderfully good graphs. And graphics!

### 5/5 — Toll!

*2022-03-29*

Super visualisation von formulas! Fur shader, visual, etc..

### 5/5 — Sehr Empfehlenswert

*2021-10-08*

Sehr gute Anwendung

### 5/5 — Where is the complex plot?

*2021-09-06*

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!

**Developer response:** Hi, thanks for your feedback.
The app supports plotting of complex equations.
You need to enable complex graphs on the settings page.

Regards
Ronny

### 5/5 — A+

*2021-07-17, version 5.3*

OUTSTANDING.
