Awesome

It’s a fantastic tool in my tutoring business. It enabled me to save the graphs, and send them to my students via text or email.
Even entertaining
AdaByron
Very nice. Hope updates can allow the user to set the resolution. It may sometimes slow rendering, but occasionally one needs very high resolution.
Great app! No iPhone X support
Waste if money
Please keep the app the way it is and add iPhone X update.
Great App
Lighthouse1991
This is a wonderful graphing app. I prefer using this over a hand-held calculator. I hope to see new features that will improve this app.
Amazing
Failuretocalculate
This app has helped me out significantly. Although I am not able to use it on tests, it has helped me with homework. It allows me to visualize graphing problems and keep track of functions on the graph with color options. It's well worth the money. Not to mention, a great alternative to buying an expensive graphing calculator.
It works very nice, but problems occur on iOS7
DefSil
This app is very useful. It is even better than most graphic calculators. But it does not support iOS7. When I want to plot a graph, this app keeps crashing. Please fix this problem.
Excellent
SummitRider
I use this instead of a graphing calculator. Easier to visualize and manipulate the graphs.
