What makes YONO different?

Accuracy

Measures core body temperature instead of skin temperature, which can easily be affected by ambient temperature.

Real time

Comfortable silicone-encased earpiece (similar to an ear bud), which is worn all night (and where data is collected) multiple times to determine the lowest BBT.

Safe

No data transmission when worn every night; the data-only syncs when the earbud is stored in the base station.

Convenient

The YONO APP uses the readings to plot a monthly BBT chart, then analyzes the data and predicts the monthly fertile window.

Science

Use machine learning algorithms to plot a monthly fertility chart to predict one’s fertile window. (YONO machine learning algorithms are based on over 10K overnight temperature data, 100 cycles from real users, etc.  YONO algorithms keep improving as we obtain more and more users).
