I have Note 3, which has 3 programs that recognize stylus-hand-written formulas in real-time: S Finder + WolframAlpha S Note MyScript Calculator (mentioned above)
Also Windows has Math Input Panel which is highly integrated with Word equations. I tried both FineReader and InftyReader yesterday and was disappointed.
