There are only a handful of days each cycle that you are fertile. Daysy uses the Fertility Tracker Method (FTM) to calculate your fertile days and predict your ovulation. Daysy is programmed with a complex algorithm which evaluates your cycle by tracking your morning temperature (taken under the tongue) and knowing when you have your period. Daysy will then show you right away if you are currently fertile or not.
Daysy is German-made, Swiss-designed, with the foundation of over 3 decades of pioneering research, innovation, and experience from our family-run company. Based on 5 million menstrual cycles and knowledge from more than 30 years of research Daysy calculates the infertile days with an accuracy of more than 99%*.
* The independently reviewed result shows that Daysy has an overall accuracy of 99.4% in the calculation of infertile (green) days.
