Venn Diagram Shader Ratings and Reviews

As a mathematical visualization tool it’s ok. The interface is not great and the documentation is, at best, subpar.

As a generic Venn diagram tool it’s useless. The poor English in the description leads the buyer to false conclusions.

I think the developer knows the app isn’t very good. That’s why there’s no trial mechanism. You’ve got to spend your $3 to find out you’ve just wasted your $3.

Hello, we are sorry for your experience. We explicitly highlighted and mentioned as the first thing that this is not a painting tool in the App Description.

I love this app. It’s really easy to use and customizable. Thanks for making it and responding to user comments.

Thank you for your feedback! The bug has been fixed in the latest version.

This app is great for developing intuition about set arithmetic. It's simple to use and provides detailed solutions. Highly recommend.

Thank you for your review! We are glad that this app has reached and delighted its intended user!

This app does exactly what I wanted. It takes a set theory expression and shows the result.

Thank your for your review. We are glad that this app meets your needs!

This app does not work on iPhone 12 Pro Max

There is an update on the App Store, version 4.8, that fixes this bug. Thank you.

I was hoping it would helped more and give more of understanding of Venn diagrams. The standard forum.

Hello, what exactly were you looking for?

If I took a quarter and threw it into a fountain, then took another quarter and threw it into the same foundation, and took a photo of the rings intersecting, it would be of more use than this app.

If I then threw a third quarter off a cliff and never again wondered about its whereabouts, I'd have only wasted 75¢ and would have still had more satisfaction than I've had from downloading this useless app.

Hello, please tell us the issues you are experiencing so that we can improve the app.

I took a chance on this app.

It had bad reviews but the developer
*did* respond to criticisms.

YOU CAN ONLY CHOOSE ONE COLOR
FOR YOUR DIAGRAM.

YES, ONLY ONE COLOR.

So, with one color you cannot overlay different colors to clarify the overlap of information.

You might as well leave them blank
and call them white.

I checked to see if I'm missing something.

If I have missed anything, I'll change my rating.

I paid $1.99 for circles with colors... all the same color.

Thank you for the very comprehensive review!

This app is intended as a mathematical tool. It is not a painting tool, hence you won't be able to annotate drawings or shade different areas with different colors. This app does not support freestyle editing because then the Venn diagrams will not be conformed for algebraic manipulation.

Nevertheless, you may create skeleton Venn diagrams in this app and export them into your favorite image editor for further editing.

Bought it to make a Venn diagram for a quick reference, but this app is actually useless. It does nothing, save your money and buy a pen and paper instead. You’re in bananaland if you buy this app. Sad!

Hello, the app now features a Venn diagram editor where you may create your custom Venn diagrams.

You can’t edit colors, can’t change labels, can’t adjust the size/proportion of the circles, and you get two or three circles. You also can’t arrange the circles.

Hello, in the latest version, you may edit col­ors, ad­just the size/pro­por­tion of the cir­cles/ellipses, and you get 1 to 7 cir­cles/ellipses. You may also arrange the cir­cles/ellipses. You may export the Venn diagram in your favorite editor for further editing. This app does not support freestyle editing because then the Venn diagrams will not be conformed for algebraic manipulation.
