Natural Cycles was founded in June 2013 by former CERN physicist, Dr Elina Berglund and her husband Dr Raoul Scherwitzl, who also has a background in physics. Natural Cycles is an effective, natural method of contraception that is delivered in the form of an app. It uses a smart algorithm that is sensitive to subtle patterns in a woman's cycle to determine daily fertility, based on basal body temperature and period data. Natural Cycles is 93% effective with typical use¹,  which means that 7 women out of 100 get pregnant during 1 year of use. Natural Cycles is the only app of its kind to be available in Europe and the US for use as a contraceptive. The app can also be used to help plan a pregnancy when the time is right. Natural Cycles' mission is to pioneer women's health with research and passion, by empowering every woman with the knowledge she needs to be in charge of her health. Natural Cycles is headquartered in Sweden and has operations in the United States, Germany, Switzerland and the United Kingdom.
