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.

By measuring your basal body temperature under the tongue every morning, Daysy calculates the status of your fertility. Sync the results of the measurements in the DaysyView app and gain access to a graphical overview of the cycle. 

During your fertile window, you can plan a pregnancy, during the infertile phase you can not. Daysy calculates your fertile window: Your fertility status will be displayed either as a red (you are fertile/possible fertile) or green (you are not fertile) light.

DAYSY is an award-winner of the renowned Red Dot Design Award in 2019. 

The Daysy 2.0 cannot be tested because of hygiene reasons, after connecting to your phone, the product may also not be returned.
