anyone heard of ovusense?

Nicola • New to this, don`t know what the abbreviated texts mean if anyone can enlighten me please :) x
I read an article on Facebook this morning about a tampon shaped device that detects with 99% success rates when you ovulate, made in U.K. I have never heard of it before anyone here hear of it?
