Non-invasive, easy, accurate.

In the past, women concerned about their fertility window had to go through a complicated process of data collection. With YONO, women have the option of letting technology do the work while gaining much more insight. YONO is an easy to use, comfortable, silicone-encased earpiece, which is worn all night. Hundreds of data points are collected during sleep, which are then synced when the earbud is stored in the base station. YONO’s earbud is the only wearable device to provide continuous body temperature data. With this unique data, YONO fertility APP not only records input from users, but also interprets BBT charts. The YONO app uses machine learning algorithms to plot a monthly fertility chart for future fertility prediction. YONO is fertility intelligence in your ear.
