How Natural Cycles works
You log your period and a daily temperature (from a basal thermometer each morning, or automatically from an Oura Ring, Apple Watch or the NC° Band). The algorithm marks each day green (not fertile) or red (use protection or abstain). FDA cleared it in 2018 through the De Novo pathway as a “software application for contraception”.
Typical-use effectiveness of 93% means about 7 in 100 users become pregnant in a year; perfect use (never having unprotected sex on red days) is 98%.
