Note Taking Software for iPad
Does anyone have any suggestions for a good note taking program for iPad? I want to be able to annotate my pdfs as I’m teaching and I usually just use Preview but it would be nice to have more math specific tools like being able to easily insert axes, etc. OneNote is okay too but I don’t like how it inserts the pages of pdfs as images inside the OneNote doc instead of just letting you write directly on top of the pdf. Any ideas?
