Meet Ava: The First Fertility Tracking Sensor Bracelet

Ava Bracelet 

Ava is the first fertility tracking device that is worn in the nighttime like a bracelet around wrist. It is accurate to narrow the fertility window to 5.3 days in a menstrual cycle .

It works by monitoring 9 physiological parameters that are in relation with the changing reproductive hormone levels. The data is gathered through night and it is fed into an algorithm. It does not rely on patient to input the data.

It measures pulse rate, breathing rate, heart rate variability, sleep duration and sleep phases, movement, skin temperature, heat loss, perfusion, and bio impedance.

Sync the data in the morning with the Ava app displays the information through several graphs along with a timeline of the cycle, which depicts the fertile window with 89% accuracy.

It saves the patient from taking the Basal Body Temperature (BBT), checking the quality of cervical mucus or doing the urine test for ovulation.

The accuracy improves with longer period of wearing the bracelet.

It is FDA registered and CE approved, based on a yearlong study at the University Hospital of Zurich led by Prof. Dr. Brigitte Leeners, who is known as an expert of mathematical modeling of menstrual cycles.

Ava is specially indicated in patients who have irregular cycles, couples who want to have timed intercourse and patients taking treatment for anovulatory infertility.  

If you get pregnant, the Ava bracelet will track you other parameters like sleep quality, resting heart rate, and stress levels.

Ava is a medical technology company founded in Switzerland in 2014 by data scientists, experts in wearable technology, and women’s health researchers bringing innovation to women’s reproductive health.

Ava is the first easy and accurate method for women to track their fertile days and ovulation,” Ava founder & CEO Lea von Bidder said. “Only worn during the night, the Ava bracelet uses completely novel technology to detect the very beginning of a woman’s fertile window. Ava is registered with the FDA as a medical class one device and has proven to be 89% accurate to detect 5.3 fertile days in a woman’s menstrual cycle.”
