What makes femSense special

High precision sensors

Exact temperature measurements without any effort: The wafer-thin temperature sensor measures reliably, without you even noticing. The app is over 93% accurate in ovulation detection.

Continuous Measurement

Body temperature rises by approximately 0.2°C during ovulation. The femSense patch continuously measures in order to identify this minute rise in temperature and the app informs you when you are most fertile.

Medically Certified

femSense is a certified medical device with a CE mark. We regularly conduct clinical studies to make the system even more user-friendly and accurate.

A Photo of Sarah, a femSense user.

I wanted to plan my pregnancy carefully, I am self-employed and wanted to optimize my maternity time. I followed my cycle with the femSense cycle tracker for a few months before using the Ovulation patches and got pregnant the first month I used the patches. Perfect timing!

I always thought my ovulation was on the 14th day of my cycle and wondered why it took so long to get pregnant. Thanks to femSense I found out that I actually ovulate on the 16th day - that made all the difference for me.
