Daysy is a medical device and lifestyle fertility tracker. Daysy is to be used to facilitate conception and track your cycle. Daysy allows every woman who wants a health-conscious lifestyle to monitor her individual monthly cycle and determine her fertile and infertile days in natural harmony with her body.

What Daysy does:

Daysy is an effective and science-based method which allows you to easily, reliably, and precisely differentiate between your fertile and infertile phases, based on the precise measurement of your basal body temperature.

How to use Daysy:

Every morning, upon waking, you measure your basal body temperature under your tongue for just 60 seconds and enter menstruation if necessary. Daysy immediately analyzes your cycle data and shows you if you are in your fertile window or not.
