The demand for non-invasive and non-hormonal birth control is on the rise. But very few methods exist to meet this demand. Natural Cycles is a digital technology that was developed specifically for this group of women. The technology has been FDA approved and teaches users about their unique cycle. Users measure their body temperature in the morning using the Natural Cycles thermometer, enter the data into the app and learn whether or not they can get pregnant that day. Natural Cycles uses an algorithm to determine fertility. The technology is effective and avoids negative side effects associated with other, hormonal, birth control methods
