Your ovulation predictor Daysy

Calculate your fertile days in seconds with Daysy!

You are looking for a modern ovulation calculator that determines your fertile days and your ovulation quickly and simply? Then Daysy is just right for you! Based on your morning basal temperature, Daysy calculates with 99,3% accuracy whether you are currently fertile and displays your ovulation reliably to you.

Daysy is easy to use: Just measure the basal temperature underneath your tongue with Daysy in the morning while you're still in bed. That takes 60 seconds. After that Daysy might still ask you to confirm that you currently have your period. And that's it. Daysy then immediately displays to you whether or not you will be fertile during the next 24 hours. The display is absolutely unambiguous and easy to understand. A green light means that you are not fertile, a red light means you are fertile and a blinking red light means that you are currently ovulating and are highly fertile.

Especially when you start using Daysy, you will be shown a yellow light on some days. The yellow light means that Daysy is still in its learning phase and has to gather more information about your cycle. You can treat yellow days just like red days. If you want to get pregnant, you should have sex on yellow and red days. This way, you increase the likelihood of conceiving.

Ovulation predictor with practical app for smartphones

Daysy is extra small and practical and has only the most necessary functions so that you can use it safely and quickly, even while you are still half-asleep. If you want to receive more information about your cycle, you can just install Daysy's app on your smartphone and synchronise the ovulation calculator with your smartphone. This way you gain insight into your cycle calendar, your temperature curve and into the practical preview for the next month. If you want, you can also share these data with your gynecologist or your partner.

The preview function of the app is especially helpful if you and your partner do not get to spend many nights together, if one of you, for instance, works late hours or travels frequently. In such cases, the right timing is particularly important in order to become pregnant quickly. With the preview for next month, you can make sure to arrange for enough time for two during your fertile days. This way, you can increase your chances significantly, even with changing and irregular living routines.
