Teachers need visible rulers! We ar waiting for you, Good Notes!
TEACHERS NEED RULERS!
Many Teachers at my school use Goodnotes as their primary Tool as a Replacement for the old classroom board. What we math teachers miss so much is a possibility to view the ruler on the beamer image like in the Notes App from Apple. The students need to see a ruler or a triangle ruler so that they can follow the teacher properly. There is no other App that does that. SO GO FOR IT! The Teachers around the world are waiting for this! If you are interested in working with a teacher for optimizing your App do not hesitate to write me an e-Mail, I would be happy to help with the development!
