Meet daysy – your personal fertility calculator.
Daysy lets you make the choice!
Daysy is a Fertility Tracker that uses the fertility awareness method (FAM) by learning & tracking your menstrual cycle. Daysy tells you when you are in your fertile window and when not. During your fertile window you can choose to plan a pregnancy, use a barrier method to prevent pregnancy, or postpone PIV (penis-in-vagina) sex to avoid pregnancy. It's your choice.
Daysy will show you if you are fertile or not with an accuracy of 99.4%. It is all natural and free of side effects. *Daysy is not a contraceptive. Daysy tells you when you are in your fertile window. During your fertile window you can choose to abstain or use a contraceptive, i.e. a barrier method like a condom.

"I have already recommended the product and two of my friends have bought Daysy! I love it! I personally dislike birth control pills. They make me.... well, not me. Other birth control methods I have heard first hand horror stories. That one story of each product makes it not worth the risk to me. This is extremely easy to do and extremely easy to remember to do. I use my cell phone as my alarm to wake up, and I keep Daysy on my night stand right next to my phone. I have been using it for the past 7 months and I love it!"-anonymous
"I recommend Daysy to everyone. She and I are good friends. Switching to using Daysy instead of the pill or other hormonal birth control was the best decision I ever made. It helped eliminate the need for not only the pill, but it also helped reduce the postpartum depression I was suffering from, and allowed me to ween off my Zolft as well. Being in touch with my body is such a wonderful feeling and I feel much more in control of not only my fertility but also my life.
"I would say that daysy is one of the most fantastic purchases I have ever made! It has taught me to listen to my body and its natural cycle rather than changing it with unnatural methods. I would most definitely recommend this product to my best friend, in fact, I have! "Natalie, student
"I would absolutely recommend it. I love daysy and how easy it is to use, plus the tracking makes it simple to show my doctor how things are going. My husband and I are both very concerned about the effects of hormonal birth control, but don't want to throw caution to the wind. Daysy makes it easy for us to monitor fertility together, without all the side effects of HBC."Lauren Halcik, HR Director
