Ratings and Reviews
Very good. Suggest improvements.
App works well. Venn Diagrams: all my Logic books show Diagonal Lines with Crosshatch Pattern for overlaps while Shading (A & E Propositions). They also place the X on the line that Divides an Area - (i.e. Some M Are P.) - instead of using 2 Xs, one on each side of the Dividing Line. It would be great to enter Custom Letters, not just S M and P for each Circle. I would love it if the Middle Term Circle could be placed Above the S and P Circles in addition to Below it. It would be Absolutely Wonderful if you would include the 9 Conditionally Valid Forms in your Listing and include the Existential Marker (X with a Circle around it) in the Aristotelian Venn Diagrams. I would be willing $10 to $20 more as an In App Purchase for this Improved Version. Thank you. John M.
Not valid education tool
Please use John’s recommendations to improve the app since it is only somewhat true based on Aristotelian Venn diagrams.
Would give it 5 stars if…
1) You could write your own titles for each circle, 2) could change the colors of a) each circle b) each overlap and c) background, 3) allowed a place for a title above the diagram, and 4) could save multiple diagrams a) in the app and b) to your photos.
I like things like this as thought tools. It would vastly increase the app’s versatility if it was more customizable.
