The Ava fertility tracking bracelet is a completely unprecedented method of tracking a woman's cycle. While you're sleeping, the conception aid's sensors monitor five physiological signals of fertility. In the morning, sync the bracelet with the app to receive Ava's fertility calculations including your fertile window, physiological stress level, sleep quality, and more.

Detects the fertile window in real time

Many other methods of fertility tracking rely on only a single parameter, so they can't provide a complete picture of your fertility in real time. Ava is a cycle tracker that uses temperature, resting pulse rate, breathing rate, heart rate variability, perfusion, and movement to detect the very first signs that the fertile window is beginning. Unlike using LH or the temperature method for fertility tracking, Ava conception aid detects the beginning of the fertile window in real time.

Accurate and clinically proven fertility monitor

Ava wearable digital cycle tracker was created by a team of doctors and researchers committed to advancing scientific understanding of the menstrual cycle. We don't just make electronic cycle trackers and conception aids, we conduct clinical studies and publish peer-reviewed papers. Ava ovulation predictor was developed in multiple clinical trials over more than4 years, and was found to detect more than 5 fertile days per cycle.
