This app has a great feature that I have the side with the English word and draw on the bottom,and then check them by myself.
But I can't draw a card directly on my iPad.This is not important when i use the app to learn a language ,but when i try to make a card with formula i found it quite difficult.I have to type the formula in Mathtype and then save them as pic and put it into iPad.So why not directly draw a card on the decive?
