The Natural Cycles certified algorithm uses body temperature to determine fertility, as there is a small, but detectable shift in temperature that happens after ovulation. Once the algorithm gets to know your unique cycle, it’s able to both confirm and predict the fertile window. For the NC° algorithm to learn your cycle you need to measure with one of our three devices. This article outlines how each device works and can help you find the right measuring option for you!
