Calculating fertile days with the calendar method?

Daysy - easy, comfortable and precise!

Daysy distinguishes your fertile from your infertile days accurately for you!  Daysy makes your natural family planning easy and comfortable. 

In order for Daysy to be able to calculate your fertile days as precisely as possible, you have to use it every morning prior to getting up. All you need to do is measure the basal temperature underneath your tongue and wait until you hear a signal sound. The measurement takes about 60 seconds! Later Daysy might ask you to confirm via the push of a button that you are currently on your period. You will immediately see via a colorful light whether you are currently fertile or not.

Red means that you are fertile / possibly fertile. If Daysy's light is green it means that you are not fertile.
