Discover your menstrual cycle – and your fertility!
Daysy empowers you to understand your menstrual cycle.
What Daysy is:
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.
Red = fertile / possibly fertileOn red days you can plan for a pregnancy.
Red flashing = predicted day of ovulation
Green = infertile daysYou are not fertile on green days.
Yellow = learning phase/cycle fluctuationOn yellow days, Daysy becomes better acquainted with you.
Red, green, yellow = possible pregnancy
You can rely on Daysy!
Daysy uses an intelligent algorithm supported by scientific evidence, long-term experience, and well-engineered technology.
Based on 5 million menstrual cycles and knowledge from more than 30 years of research, including several studies, Daysy fertility tracker calculates with precision your fertile and non-fertile days each cycle.
You can start using Daysy on any day of your cycle. While your fertility status is displayed as a light on the Daysy device itself, you can gain further insight into your cycle, including predictions and history, by transferring that data via Bluetooth to the DaysyDay app.
Daysy’s algorithm is the same used by our Lady-Comp device for over three decades, the fertility tracker that kickstarted our parent company Valley Electronics. As pioneers of fertility tracking technology, we have supported some 500,000 women in getting to know their body better.
