Venn Diagram Shader

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

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.

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