This FDA-approved bracelet tracks fertility

Today, medical technology company Ava launched its first product, a bracelet that helps detect a woman’s fertile window. Women wear it at night and its sensors collect three million data points—including pulse, breathing rates, sleep quality–and temperature that correlate with the rise in the reproductive hormones estradiol and progesterone. 

It has received FDA approval and was clinically proven, in a study at the University Hospital of Zurich, to detect an average of 5.3 fertile days per cycle with 89% accuracy.
