femSense measures your ovulation and tells you when your fertility is at its highest.
How does femSense work and how can we reliably calculate your ovulation?
Continuous temperature measurement

The femSense Patch measures your body temperature around the clock for up to 7 days per cycle. The app then tells you when your fertility is at its highest and subsequently confirms your ovulation.

femSense predicts your fertile
days based on your cycle data and confirms your ovulation by the rise in your body temperature.

There is a direct correlation between body temperature and ovulation. 

Although the rise of just a few tenths of a degree is tiny (only around 0.2°C to 0.5°C), it is a direct result of ovulation and a sure sign that your ovulation has taken place.
