Ava is a fertility tracking bracelet that detects five fertile days per cycle in real timeâ€”more than any other method. It brings together sleep, stress, and menstrual cycle monitoring into a single device, worn only at night.
Ava tracks a woman’s cycle in a fundamentally different way than any other method available, monitoring subtle changes in pulse rate, breathing rate, sleep quality, movement, heart rate variability, skin temperature, heat loss, perfusion, and bioimpedance. By tracking a wide variety of parameters, Ava can detect the fertile window in real-time during a woman’s current cycle.
We built Ava because we believe that women deserve a more modern method of tracking their cycles. They deserve accurate, reliable data about when they’re ovulating, delivered in a way that’s convenient, non-invasive, and fits into their lives.
Ava is an FDA-approved Class 1 medical device. It was shown to detect an average of 5.3 fertile days per cycle in a year-long study at the University Hospital of Zurich. iOS only, Android coming soon.
