Daysy is so simple to use, you will soon be able to use it while you are still half-asleep. The display of the result is straightforward and unambiguous. If you are currently fertile, you will see a red light. On the day you are ovulating, the red light is blinking. If you are not currently fertile, you will see a green light. On some days, most probably in the beginning of your use, Daysy will also display a yellow light. This means that Daysy is still getting to know your cycle, or that your cycle is currently irregular.
