How does femSense work and how can we reliably calculate your ovulation?

Continuous temperature measurement

The femSense Patch measures your body temperature on the side of your breast around the clock for up to 7 days per cycle. You can do everything and don't have to worry about anything. The app will tell you when your fertility is at its peak and confirm your ovulation.

The rise in body temperature from around 0.2°C to 0.5°C is a direct result of ovulation and a sure sign that your ovulation has taken place. 

The algorithm of the femSense App predicts your fertile days based on your cycle data.

Our Smart sensor patch then confirms your body temperature based on the rise in your body temperature. individual Ovulation
