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

The ovulation tracker Daysy - calculating ovulation made easy

Help a pregnancy along with the right timing!

Do you want to have a baby and boost your natural chances to become pregnant more quickly? Then Daysy is right for you! Daysy is a highly modern ovulation monitor that can calculate your fertile and infertile days with an accuracy of 99,3% based on your morning basal temperature. All you have to do is measure the temperature underneath your tongue every morning before you get up. The measurement takes only 30 to a maximum of 60 seconds! After that, Daysy might ask you to confirm if you currently have your period. This too is done via the simple push of a button. Daysy then displays to you via a colorful light whether or not you will be fertile within the next 24 hours.


A green light means that you are not fertile and it is highly unlikely for you to become pregnant. A yellow light means that Daysy still needs to get to know you a little better or that your cycle is a little bit irregular. A red light means that you are currently fertile and can become pregnant. Of course, Daysy also shows you when you are ovulating: In that case, the red light is blinking. To make the best use of your chances to become pregnant quickly, you should have sexual intercourse with your partner on the red days, the day of your ovulation and also on the yellow days.

Perfect timing thanks to the ovulation tracker Daysy

For many couples with an unfulfilled wish to have a baby, there are no physical reasons that prevent a pregnancy, rather, it is an issue of the right timing. In our modern and fast-paced world, undisturbed time for two can be quite rare. Conflicting schedules, various free time activities and commitments can let sex fall by the wayside. In particular, when you want a baby but can never make it work at the right times, that can be quite frustrating. Daysy makes timing much easier, because you know exactly when it makes sense to take some time for romance. On your infertile days, by contrast, you no longer have to worry about getting pregnant, because you cannot get pregnant during those days anyway.

To make it even easier for you, Daysy comes with an app for your smartphone: DaysyView displays your cycle calendar, your temperature curve and a practical preview for the next month. You can use this preview to plan for enough time with your partner during your upcoming fertile days.
