Unfortunately it is no has on Apple, App Store. Just on Google Play Store (Android) and Windows desktop.
Actually need some healing updates and turning to Apple (Ios) but not enough time and support to work on project. :(
I guess needs Xcode to ios turning, therefore needs MacOS. But still it is powerful, you can define your problem (Algebra to Differential equations), 3D-2D graphs...
so I hope it helps a lot of students that if need to calculate any hard mathematical problem only on mobile phone. Powerful, because of based SymPy and Matplotlib Background.
But I'm still thinking to new interface that includes all students related math. (like Photomath's mathematical symbols on buttons)
::a memory;
I'm bored in dorm and raining outside, then yes we can do something; create an equation about of limit speed of rain drop.
at last, there is a differential equation occurred of Newton's 2nd law. Then I calculated this differential equation with my app. I was feel good :)
