Take control

... of your fertility

Based on the well-known temperature method trusted by generations of women to plan or prevent a pregnancy, femSense is the fastest way to find out when you are most fertile. The sensor patch measures your body temperature 24/7 during your fertile window and notifies you via the femSense app when you are fertile and when you have ovulated.

Your Fertile Window

The days in the month when you might get pregnant.

There is only one truly fertile day per cycle - the day of ovulation. However, because sperm usually survives for up to 72 hours you have a fertile window of approx. 4 days during which time it is possible to get pregnant. These are the days shortly before and immediately after ovulation. If you know these days, you know when fertility is very high - and when it is very low.

The power behind the patch

High-Tech sensor technology and NFC

Thanks to femSense the temperature method has finally entered the 21st century. The high-tech sensor patch measures and records body temperature 24/7 during the fertile window. The recorded data is transferred to a phone using NFC, radiation free technology, where the femSense app algorithms analyze the information before displaying the fertility status in the calendar.
