Daysy - your personal fertility tracker
Daysy gives you the choice!
Daysy is a fertility tracker that uses the fertility awareness method by learning and tracking your menstrual cycle.
Daysy calculates your fertile window: Your fertility status will be displayed either as a red (you are fertile) or green (you are not fertile) light.
Daysy tells you when you are in your fertile window and when not. Daysy is not a contraception.
Only 30-60 seconds per day!
Red = fertileOn red days, you can plan for a baby.
Red flashing = day of ovulation
Green = out of your fertile windowYou are not fertile on green days.
Yellow = learning phase/cycle variationsOn yellow days, Daysy becomes better acquainted with you. If pregnancy is out of the question for you right now, consider these days as red and use a barrier method of your choice or postpone PIV (penis-in-vagina) sex.
You can count on Daysy!
Why is Daysy so reliable? The fact that Daysy can determine your fertile days is due to the extensive database. Based on 5 million menstrual cycles and an algorithm that draws on knowledge from more than 30 years of research, including clinical studies, Daysy can give you reliable information about your menstrual cycle.
You can start with Daysy on any day of your cycle. Our customers appreciate the fact that measurement and fertility indicators can be seen independently of smartphone integration. Connecting to your smartphone is relevant for details and special features, e.g. if you want to display your menstrual cycle history or share it with your partner or doctor.
The algorithm of Daysy, which is also used by the well-known Lady-Comp fertility tracker of the sister company, has proven its safety for more than 3 decades. You will notice how exciting it is to get to know your body better with Daysy!
Medical basics related to the female cycle
Every woman is different,
but there are some basic physiological facts about the woman's menstrual cycle that you should know:
- As a rule, every woman has only one ovulation per cycle.
- If two or more instances of ovulation occur, they take place within 24 hours.
- After ovulation, the ovum can be fertilized within 18 hours at the most.
- Sperm is able to move and fertilize in a woman's body for a maximum of 5 days.
This means that pregnancy can occur on only 6 days, i.e. 5 days before ovulation and on the day of ovulation itself. Daysy calculates these 6 days, plus provides buffer days.
How exactly does the Daysy work?
Daysy uses a morning measurement of your basal body temperature to detect ovulation in your cycle. Just measure the temperature under your tongue in the morning and you will know whether you are fertile or not.
Depending on the current cycle phase, the indicator lights red or green.
In addition, Daysy records your menstrual cycle history and DaysyView shows you your past and and present cycle data. It is hardly easier to become aware of your body.
