i been using notes so far, are there any apps that are better suited for math and physics equations? i find my notes a bit disorganized due to the way notes is set up, and would like an app that has graphing function as well.
Nebo is interesting as it can translate math symbols well.
I use Concepts. It has a bit of a learning curve but has a number of tools for free form drawing. Everything is a vector so you can move and scale things.
Tip: if you will be sketching a lot of graphs and charts you should get a plastic ruler or triangle to draw straight lines with the Pencil.
