The Ava Bracelet
The Ava bracelet was launched in the US in July 2016, and is now sold in 36 countries worldwide. Worn only during sleep, it provides women with real time, personalized information about fertility, pregnancy, and general health—delivered in a way that is convenient and non-invasive.
Ava published a peer reviewed clinical paper in the Journal of Medical Internet Research which demonstrated changes in 5 physiological signals during the menstrual cycle*. The study found that by tracking these 5 signals simultaneously, Ava can detect 5 fertile days in real time. No other method tracks all 5 of these signals.
