You can do a lot of beautiful mathematics with this app via custom subscripts & superscripts, various exotic symbols, etc. Yet the program is sooo buggy that it's practically unusable and only wastes your time: it's a bit hard to copy and paste (does not always work!) for one reason or another, undos sometimes fail to work, what's even worse - saving often(!) fails. Uninstalled after I had to rewrite the start of my document 5-6 times and it failed once more. Needs rewriting!

GREAT! The interface is ugly but i work with R, MATLAB and software alike, so that's no issue. I would give up pretty UI's for the amount of mathematical symbols this has, any day. It gets the jobs done, the results look awesome and the ability to export directly to image makes it the best one. I think a strike-through format for text would be perfect when, for example, showing similar terms being reduced. I simply color them red, but yet again, I already know what I'm doing; my students don't.
