Ratings and Reviews

Would love a save feature


Would be nice to save templates to come back to and re-use to save the trouble of starting from scratch every time. Thanks

Nice idea, horrible execution


The ux/ui is awful. No touch control at all. Nice idea but just so poorly designed it isn't really useful.

Favourite App for Representing Mathematical Thinking

math barb

Just love this app for showing my thinking in math.
I can use the number line features to order, compare and operate with whole number, integers, decimals and fractions. Being able to quickly make an array of any dimensions, I can model whole number multiplication and fraction +,-,/,x!
The copy feature makes graphing and labeling so easy!
I love being able to annotate my thinking with either a text box or by using the pencil tool.
How great is it that I can bring in an image to find the area of or maybe import a screenshot of the problem I'm solving!
Finally - being able to save my work, allows me to come back to it or even share it, and show the steps I used by clicking the undo button!
