However, since most of the things I'll need to revise will be partly symbolic, I was wondering if there was any way to put LaTeX ( or some kind of TeX ) in flashcard form on the phone, since the majority of the apps I've looked at don't seem to have much in the way of special character support ( logic symbols etc )-if there is such an app I've failed to spot it, but either way a nudge in the right direction, if this is feasible, would be much appreciated!
