Ava Fertility Tracker

A woman’s “fertility window,” when conception can happen is only about 6 days out of 28, and only three days when fertilization is likely. To target this timing, a Swiss company, Avawoman (Zurich) had designed a bracelet (actually more resembling a wrist watch) that continuously tracks pulse, respiration, heart rate, sleep quality and temperature (correlating with the rise of estradiol and progesterone) that signal an open window. This device supposedly has an 89% accuracy rate, and costs $199. MORE
