femSense – from cycle tracker to Ovulation Detection

Track your fertility cycle with the app and get to know and understand your own body better; and when you are ready to start a family you can combine the app with the femSense Ovulation Detection patch. This revolutionary patch can detect your ovulation and therefore help you get pregnant quicker. It is hormone free, discreet and completely natural. And your personal details? Safe, anonymous and protected!

femSense Ovulation Detection
Becoming a mother has never been so easy! femSense Ovulation Detection is the newest and most innovative way to detect ovulation and your fertile days, discreetly, non-invasively and, with the femSense sensor, accurately.

It´s so easy:
Download the app, register, buy your patches in the app and start femSense Ovulation Detection. femSense will guide you every step of the way, tell you when to apply the patch and when you have your fertile days. As soon as ovulation has been detected femSense will let you know, and you can remove the patch. The discreet patch must only be worn for a few days during your cycle.

With femSense you can:
• Plan your pregnancy for when it suits you

• Narrow your fertile window down to 4 days per cycle

femSense also offers:
• Precise sensor technology; continuous and exact temperature measurement without any effort
