Daysy - your personal fertility tracker

Daysy is the hormone-free device for managing your fertility, cycles, and health. Daysy calculates when you are fertile and when you are not. On your fertile days, it is possible for you to conceive; outside of your fertile window, it is not. Daysy supports you in empowered and informed decision-making.

• Daysy is German-made, Swiss-designed, with the foundation of over 3 decades of pioneering research, innovation, and experience from our family-run company.
• Daysy distinguishes between non-fertile and fertile days with an accuracy of over 99%.
