Daysy does not equate contraception! We help you to determine exactly WHEN you have to use contraception.

Determining fertile days and preventing a pregnancy

When are your most fertile days? Daysy helps you!

You want to prevent a pregnancy but want to avoid permanent methods of contraception such as the pill or the IUD? Then Daysy is right for you! Daysy determines your fertile days for you and displays to you daily whether you have to use contraception or not.

It can be very time-consuming to determine fertile days when you have to do the measurements and calculations all by yourself. With the common, manual method without a cycle monitor like Daysy, it is very important to work precisely and evaluate the data of possibly several indicators. For instance, your temperature curve, the changes in your cervical mucus and the condition of your cervix. Through the combination of these methods you can receive a relatively accurate result. These methods do, however, require some practice and a lot of time, every day. Daysy is the comfortable alternative, because it does all the work for you!
