I was just forwarded a link to an app (Hat tip Mom in Israel) that walks women through determining if their discharge renders them a niddah without needing to ask an authority.
Move over rabbis and yoetzet halachot! Sisters are doing it for themselves! 
Ain’t technogy grand? Who needs religious authorities when we have Siri and phone apps?
I do like the concept of women having more autonomy over their own bodies and shailahs. However, I can imagine that not everyone will be excited about the move away from human counsel and into the age of computerized paskening.
