### 5/5 — Great for Set Theory

*2023-03-18*

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

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

### 3/5 — Meh. Do it in paint.

*2022-04-18*

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.

**Developer response:** 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.

### 5/5 — Great

*2021-06-14*

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

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

### 1/5 — Does not work

*2021-05-04*

This app does not work on iPhone 12 Pro Max

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

### 3/5 — ...

*2020-08-23, version 4.3*

I accidentally bought this because I thought it was free... oops. So I went on it and it’s VERY basic, I don’t recommend :( 

Wow, I’m pleasantly surprised that I received a response but for £2.99 it seems overpriced for what it is but it’s your app, so it’s all up to you. Maybe if you could include numbers in the Venn diagrams and use the app to do different calculations, that would be fantastic :) I’m very sorry for the previous harsh review x

### 1/5 — Not very useful

*2020-03-08*

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

**Developer response:** Hello, what exactly were you looking for?

### 5/5 — THANK YOU!!!

*2020-01-31*

Gosh, this has saved my butt big time. It helped me to understand three set shading. I can’t thank you guys enough. It worked perfect. And showing the steps also made me understand the process MUCH better. Worth the price. It’s not even that much either, so it’s worth the download and purchase. No need for subscriptions and stuff. Thank you guys!!

**Developer response:** Thank you for taking the time to leave us such an amazing review! We are equally thrilled that this app contributed to your positive experience of working with sets. Thank you again for your kind words!

### 1/5 — Just google image search venn diagrams

*2020-01-09*

This app doesn’t actually do anything except shade 6 pre drawn Venn diagrams.

**Developer response:** Hello, the updated app allows creating your own customized Venn diagrams. You may also select from 18 preset Venn diagrams.  By shading the Venn diagrams, you obtain the equivalent algebraic expressions. You may also enter an algebraic expression and step-by-step shading instructions are displayed.

### 5/5 — good app

*2019-05-24*

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

**Developer response:** Thank your for your review. We are glad that this app meets your needs!

### 1/5 — Super silly

*2019-03-15*

Who wants a Venn diagram you can’t write on?  Complete waste

**Developer response:** Hello, you may wish to create your Venn diagram layout and then export it to your favorite editor for writing. This app does not support freestyle editing because then the Venn diagrams will not be conformed for algebraic manipulation.
