Meet Daysy: Your modern ovulation predictor

Know your fertile status within seconds with Daysy!

Are you looking for a modern ovulation predictor that determines your fertile days and ovulation date quickly and simply? Then Daysy is just right for you! Based on your morning basal temperature, Daysy calculates with very high accuracy whether you are currently fertile and reliably determines when you are ovulating.

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 about 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 you are fertile or not. The display is absolutely unambiguous and easy to understand. A red light means that you are currently fertile/possibly fertile and can become pregnant through unprotected sex. A green light means that you are currently not fertile.

A yellow light indicates that Daysy is still getting to know you or that your cycle is currently irregular. The algorithm first needs to acquaint itself with you and your cycle. Simply treat the yellow days like red days and you might succeed in boosting your chances for a quick conception.
