Medical technology company Ava is touting a fertility bracelet that works with a smartphone app.
The tracker device, which is FDA approved, is worn at night. While the wearer is sleeping, it collects three million data points related to the reproductive hormones estradiol and progesterone, including pulse and temperature.
The bracelet then shares the data, which includes fertile dates, with the app. Ava was clinically tested in a yearlong study in Zurich, Switzerland.
