Modern, Research-Based Fertility Tracking

When calculating fertility for pregnancy with natural family planning, Cycles takes advantage of scientific research developed by the institute for Reproductive Health at Georgetown University. Known as the Standard Days Method (SDM), it is more accurate than the 'rhythm method' of yesteryear and has a real-world failure rate comparable to that of condoms. Even so, this app is designed for informational purposes only and should not be used to prevent pregnancy.
