What is Natural Cycles?

Natural Cycles is a technologically advanced fertility app that helps to prevent or plan pregnancy naturally without hormones. 93% effective with typical use, and 98% effective with perfect use.

The NC° app is powered by a smart algorithm that analyzes hormone-driven temperature changes to determine an individual’s daily fertility status. 

While using NC° Birth Control, users can prevent pregnancy by using protection or abstaining from sex on fertile days. Users can also use NC° Plan Pregnancy to pinpoint ovulation and conceive faster.

Once pregnant, users can monitor their body and baby’s development with NC° Follow Pregnancy, and after giving birth, they can support their recovery with NC° Postpartum.

How does it work?

The clinically-validated algorithm behind the app uses body temperature, menstruation data, and optional luteinizing hormone (LH) test results to determine the fertile window. It confirms ovulation by analyzing temperature shifts caused by hormones.

Temperature data can be measured with an NC° Thermometer upon waking up or by wearing a measuring device like an Oura Ring or compatible Apple Watch overnight. With the data, the algorithm learns the unique pattern of a cycle to identify daily fertility status. This is given as either a Red (fertile) Day or a Green (non-fertile) Day. 

Where does it fit in the contraceptive landscape?

NC° Birth Control is 93% effective with typical use and 98% with perfect use. In order to use the app perfectly, users must use protection on Red Days. Its FDA clearance is based on a study of over 15,000 women while its certification in Europe is based on 22,000.

Unlike other traditional, less effective FAMs or unregulated tracking apps, Natural Cycles adapts to the individual, pinpointing and confirming their specific ovulation. This means Natural Cycles works with irregular cycles or conditions, such as PCOS, helping them gather data to present when discussing potential health concerns.

How has Natural Cycles contributed to research?

Scientific research and collaborations within healthcare are a pivotal part of Natural Cycles. From studies on cycle length to time to pregnancy, we’ve published a selection of peer-reviewed papers.
