Fertile days calculator Daysy: Take your temperature in 60 seconds
One of Daysy's big advantages is its high precision test prod that takes your basal temperature in under 60 seconds. Measure in the morning while you are still in bed and have your fertility status be determined. This high degree of accuracy would not be possible without Daysy's unique algorithm, built from the knowledge of 5 million recorded and analyzed cycles. More than 30 years of research and development have gone into making it. You can benefit from all that every day when you are using Daysy.
Compact design and clear color display
Daysy is not only quick in taking your temperature, it also displays the result quickly and clearly. Red light means you are currently fertile/possibly fertile and green light means infertile. When the red light is blinking, you are ovulating. If Daysy is showing you a yellow light, it means that she is still getting to know your cycle or that your cycle might be somewhat irregular. Just treat the yellow days like red days.
You will be excited to see how small Daysy is: The device will fit into your smallest bag, even the pocket of your pants. It is hardly bigger than a conventional thermometer. If you are after more information regarding your cycle than is displayed on the device, you can additionally install the free app DaysyDay on your smartphone. DaysyDay gives you an overview of your current cycle data, lets you study your temperature curve and check out a prognosis of next month's fertile and infertile days.
