Used to be great
I bought this app last year for doing demonstrations in my class and it was wonderful. The newest update is just awful. The images are not as crisp as the previous version so on a projection system they are now blurry. The pen option keeps opening the colour selection hiding part of the screen, the coordinates app used to be so easy to change simply dragging the lines back and forth or up and down, now your stuck with preloaded 1 quadrant or 4 quadrant. The number line was easy to customize and now is stuck with very limited preloaded options. I was ready to renew the app this year but I will be looking for something else now. Please consider going back to the previous version is was much better to use and look at.
