About Ava

Ava is a fertility tracking bracelet that uses groundbreaking new technology to detect an average of 5.3 fertile days per menstrual cycle in real time, doubling a woman’s chances of conceiving. No other method of fertility tracking provides as many in-cycle fertile days. 

With Ava, the work of fertility tracking—which disproportionately falls to women—is radically reduced. There is no longer any need to take temperature at the same time every morning, go through multiple urine tests each month, nor enter data into an app every day. Because Ava detects physiological signs of ovulation days in advance, couples can relax and enjoy the journey to conception.

How Ava Works

Worn only at night, the Ava bracelet collects more than three million data points and measures nine physiological parameters. In addition to information about their fertility status, Ava provides users with health insights on sleep, stress and resting heart rate. It can be used before, during, and after pregnancy.

Ava completed a year-long clinical study at the University Hospital of Zurich under the lead of Prof. Dr. Brigitte Leeners, the leading expert on the mathematical modeling of menstrual cycles. Ava was found to identify an average of 5.3 fertile days per cycle with an accuracy of 89 percent.

The results of the study were presented in June 2016 at the Swiss Society of Obstetrics and Gynecology Annual Congress and will be presented in October 2016 at the German Society of Obstetrics and Gynecology Annual Congress. Bayer, the leading women’s health company, is sponsoring Ava’s presentations.

Our scientific research paper will be submitted in summer 2016. We expect it to be published by a leading peer-reviewed journal in reproductive health by the end of 2016.
