Why a fertility tracker will make your life much easier in many ways
For women, side effects that are caused by contraceptive methods can seriously affect their health and well-being. Many women are therefore extremely dissatisfied with common contraceptive methods – with good reason!
But it doesn’t have to be that way. Imagine…
- ...from now on you could do without the pill for all time!
- ...you could leave mood swings and other side effects behind you!
- ...you wouldn't have to rely on condoms anymore!
- ...you could do without invasive methods like coil and the like!
- ...you would no longer have to keep time-consuming and complicated cycle charts!
- ...and you could finally be in harmony with your own body!
Rather than taking synthetic hormones in the form of the pill, which can affect you both physically and emotionally, or meticulously and consistently recording your cycle month after month (including complicated calculations and the worry of whether everything has been correctly noted down and analyzed), being in the know about your fertility status can be much easier and natural at the same time.

This is what our Daisies say:
Daysy is a convenient and reliable alternative to all of the hormonal birth control options out there. I strive to respect and understand my body and Daysy allows me to do just that. I know that I am not negatively impacting or confusing my body with hormones which often has long-term consequences and I don't have to be bothered with cumbersome and unreliable barrier methods anymore. And, let's face it, the tech-loving-girl that I am appreciates the graphs and charts on Daysy. Birth control? There's an app for that! I love my Daysy. -Erin Hollier, freelance writer
Daysy is so easy to use and what you get out of it is this wealth of information about your body. I now know the rhythms and the health of my body, no guessing. I love Daysy and have told all my friends about it. - Mari, Teacher.
[Daysy] is a useful tool that has helped my husband and I grow together by learning about my cycle. I would highly recommend it as a better way to approach family planning. It is easy to use. - Leda Wolk, private chef
I love that [Daysy is] hormone free, which means a healthy way to manage my cycle. I used to be on the pill and once I realized how bad it was for me I immediately switched. I always tell my friends that the Daysy helps me understand my body and feel more connected to my cycle instead of thinking [of] it as a separate part of me. - Brie Richardson, senior marketing coordinator
Daysy is a safe alternative to taking birth control (hormone) pills. I took birth control for 6 years and imagine how much harm I did to my body in that time. Just think about the huge rise we have seen in hormonal cancers and fertility problems. I was nervous about using the Daysy but it becomes a part of your life and it's easy to use.- Sydney Kerlin, student
I would definitely recommend [Daysy]. Birth control negatively messed with my hormones and did the same with so many other women I know. It is not natural to take hormones to prevent pregnancy. I'm so happy there's Daysy where I can naturally prevent pregnancy without ANY side effects!
Highly recommend Daysy because it is hormone-free, easy to use, and is backed up by awesome customer service. - Lisa, student
I would absolutely recommend [Daysy]. 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 [hormone birth control] - Lauren Halcik, HR Director
Daysy allows me to take control of my cycle without hormones or side effects. I can use Daysy and not have to worry about making errors the way I would with the calendar or mucus method alone. I can be confident that I am understanding my body well and being responsible with my future! - Anonymous, high school math teacher
I would highly recommend Daysy. It's great to be off unnatural medication that is not good for my body. It is just as effective as the pill, as I have been avoiding pregnancy for 7 months now with no problem. When I do decide to have kids it will be very helpful at that time as well. The investment is well worth it in the long run. The device is easy to use and the app makes it easy to see all your data. - anonymous
It's the best birth control if you don't want to put hormones in your body.
- Kathrin, student

As one of the leading companies in natural family planning, Valley Electronics has perfected its methods and algorithms in over 30 years to track a woman's menstrual cycle and predict when she is fertile and when not. Launched in 2014, Daysy is the latest invention from Valley Electronics; a device that combines years of experience, research, and advanced technology to provide modern women with a reliable and easy-to-use fertility tracker.
The Valley Electronics team of gynecologists, fertility experts, software engineers, and electronics engineers have worked together to analyze over 5 million menstrual cycles. Lady-Comp, the company's leading product in recent decades, has provided unparalleled depth of research and experience, which is now also being used in Daysy – an easy-to-use fertility tracker for the ambitious woman of today.
A personal statement from the inventor of Daysy
Hello, my name is Natalie Rechberg, and I am the inventor of Daysy.
I grew up with natural family planning because my father developed the Lady-Comp, which has been successfully on the market for more than 30 years. But although I spent my whole life in this environment, I followed the trends of my friends and tried out various contraceptive methods at a very young age. I quickly learned that this was not such a good idea for me and my body. Like so many women, I suffered greatly from the side effects of hormonal contraceptives. My personal experience had taught me that natural contraception was best for me, so I started using the Lady-Comp again.
From then on, I began to immerse myself intensively in the topic of “natural fertility management” and became an expert in this field. I also completed a training as a yoga teacher and continued my education in the areas of health and wellness for women.
Today I am a cycle nerd! I created Daysy for women who find the traditional NFP solution with pad and pencil too complicated and time-consuming. Daysy combines 30 years of experience and research with the latest technology to help women safely and confidently manage their fertility.
Get Daysy now and enjoy the liberties of natural family planning!
