• How does the femSense fertility tracker work?

  femSense is based on the temperature method that has been used by women for generations to plan or avoid pregnancy. Originally, this method uses a thermometer to measure your basal body temperature when you wake up in the morning. femSense, on the other hand, measures your temperature throughout the day using a high-precision temperature sensor embedded in a skin patch. You only need to read the sensor twice a day with the help of the app so that the algorithm can process your data correctly anFew readers

• Is femSense a method of contraception?

  femSense can help identify days of high fertility and days of low fertility. femSense alone is not a form of contraception (and is also not approved as one) but rather a tool that, when used in combination with other hormone-free fertility awareness methods of ovulation detection, can be used for the fertility awareness method of birth control. Certain medical conditions prevent femSense from reliably measuring ovulation. For more information please see When can femSense not be used (/en-us/aFew readers
