I've got a bluetooth keyboard and an iPad I plan on using for notes in my classes, but I've found that in math class writing equations and using proper formatting can be a pain or impossible, and I don't really feel like using Penultimate would beat pencil and paper by much. I searched around for an app that has the capabilities of entering complex math symbols and found Tex Touch. It's great and works through Dropbox but I'm not entirely clear on the use method of the app. Would it be fast enough to use to write equations compared to pencil on paper? And after doing so, all I have to do is sync to computer and compile into a pdf for reviewing/reference? Sounds pretty cool if it's fast and has a smooth export workflow. Right now I'm trying out smartNote and seeing if the "drawing" method of entering equations works out. Judging from the app screenshots, taking math notes seems to be a use case, so I hope it works out. I'll report back with any comments on the app. Does anyone know of any other apps that can be used for writing math notes? Thanks!
