About Natural Cycles
Our mission at Natural Cycles is to pioneer women’s health with research and passion – by empowering every woman with the knowledge that she needs to take charge of her health.
Millions of journeys, each one unique
Natural Cycles is the only 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.

How does Natural Cycles work?
Backed by science, the NC° algorithm is powered by body temperature.
How to use Natural Cycles: Choose your device and measure either overnight or in the morning.
Open the NC° app: The algorithm behind the app is analyzing your body temperature.
Confirm your fertility status: At a glance, know if today is a Green Day (not fertile) or a Red Day (use protection).
Body temperature and the cycle
Our hormones cause body temperature to rise around ovulation. By analyzing this we can pinpoint where you are in your cycle.
