Daysy - your personal fertility tracker
Daysy empowers you!
Daysy is an intelligent fertility tracker that lets you get to know your very own menstrual cycle. Thanks to Daysy, you know exactly when you are in your fertile window and when you are not.
During your fertile window you can plan a pregnancy, during your infertile phase you can not.
Daysy calculates your fertile window: Your fertility status will be displayed either as a red (you are fertile / possibly fertile) or green (you are not fertile) light.
You can count on Daysy!
Why is Daysy so reliable?
Due to an intelligent algorithm based on scientific evidence, long-term experience and well-engineered technology, Daysy provides highest quality, reliability and precision in terms of fertility tracking.
Daysy determines your fertile and infertile phase using an extensive database and proprietary algorithm. Based on 5 million menstrual cycles and an algorithm that draws on knowledge from more than 30 years of research, including several studies, Daysy fertility tracker can give you reliable information about your menstrual cycle and fertility.
You can start your temperature measurement with Daysy fertility tracker on any day of your cycle. Our customers appreciate the fact that measurement and the menstrual cycle indicators can be seen independently of smartphone integration. Connecting to your smartphone is relevant for details and special features, e.g. if you want to display your menstrual cycle history or share it with your partner or doctor.
