About Natural Cycles
Millions of journeys, each one unique
Natural Cycles is the first app to be FDA cleared as birth control. Natural and non-invasive we offer a brand new, revolutionary birth control option that’s given millions of individuals the power to go hormone-free.

Elina’s story: Why I built the first birth control app
It sounds counterintuitive to many, but I actually came up with the idea for Natural Cycles birth control when starting to think about planning my own pregnancy. At the time, I was working as a particle physicist at CERN (European Organization for Nuclear Research) and my husband and I were starting to talk about our future family.
I had been using a birth control implant throughout most of my twenties after a negative experience with the birth control pill. While the implant worked quite well, I knew we wanted to start trying in a year or two so I wanted to remove it. In addition to it being invasive, I also wanted to take a break from hormonal birth control to give my body a chance to get back to its natural state well before a pregnancy.
I quickly realized I was extremely limited when it came to finding a regulated birth control option that was both non-invasive and non-hormonal. As a particle physicist and researcher, I decided to take things into my own hands so I developed Natural Cycles, the first FDA cleared birth control app. The app analyzes a woman’s body temperature to determine when she ovulates and when she is and isn’t fertile. After my own struggle to find a natural, effective contraception, I’m proud to share Natural Cycles with thousands of women around the world.
Science is at the heart of what we do
Natural Cycles is grounded in science, from our origin story to the regulated processes we follow every day. Our in-house Medical, Algorithm, and Data Team is made up of fertility experts, physicists, and data scientists. We are constantly looking for ways to enrich the field of female health, collaborating with academics, scientists, and doctors around the world. Do you share our mission?
"Natural Cycles plays a huge role in women's lives, which humbles us. So we always have their best interest at heart in every decision we make."
Meet the people behind Natural Cycles
We are scientists, feminists, friends and Cyclers too
The Natural Cycles Team is made up of people from over 20 different countries with backgrounds in everything from astrophysics to creative writing. Together we share a passion for science, data and female health.
With a caring and supportive culture, we’re proud to be part of a predominantly female team working for something we really believe in.
