Thank you. ### 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? ### 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. ### 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. ### 1/5 — This app is actually useless *2018-10-04* 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! **Developer response:** Hello, the app now features a Venn diagram editor where you may create your custom Venn diagrams. ### 1/5 — READ THIS BEFORE PAYING FOR THIS APP! *2018-08-08* 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. **Developer response:** 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. ### 1/5 — Barely a proof of concept *2018-07-04* 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. **Developer response:** 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. ### 1/5 — Waste of $$ *2016-02-05* No stars for this app as is worth less than what I paid for it.. Wish I had read the fountain review before i wasted my money on this p.o.s. **Developer response:** Hello, please tell us the issues you are experiencing so that we can improve the app. ### 1/5 — No value at all *2015-09-28* 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. **Developer response:** Hello, please tell us the issues you are experiencing so that we can improve the app. ### 1/5 — Lame *2014-09-09* Doesn't let you add text to your diagram or save it as a JPEG. **Developer response:** Hello, in the latest version, you may export the diagram and edit them using your favourite editor. This app does not support freestyle editing because then the Venn diagrams will not be conformed for algebraic manipulation. ## Most praised reviews (9 highest-rated) ### 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! ### 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. ### 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! ### 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! ### 4/5 — Nearly very good *2015-08-08, version 1.0* I wasn't totally sure what to expect with this app but when I started using it I could see that it is really well thought out. I like it. There is one aspect that I found disappointing and that was the size of the objects on the screen. The Venn diagram is too small: there is a vast space around it so why not enlarge by a factor of two or so. The font size is also too small. The technical side is good, the aesthetic side could be worked on. All in all I still like this app. ### 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. ### 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 ### 2/5 — Does what it says. *2018-03-28* And that’s about it. Should only charge 99 cents. **Developer response:** Over the years, we have added plenty of features. Please check them out! ### 2/5 — Symbol legend *2017-10-11* You should have a symbol legend **Developer response:** Thank you! In the latest version, the symbol legend has been added in the screen where expressions are entered! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
