A birth control app called Natural Cycles has been found to be as effective as birth control pills, but with none of the side effects, according to one of Sweden's most acclaimed medical institutes, the Karolinska Institute. It's so effective that it's been granted medical approval to be used in the EU, writes Claire Cohen in The Times Live. The app works by calculating where women are in their menstrual cycle and then alerts women as to when their most fertile days are, which helps pregnancy prevention.
The new Natural Cycles birth control app is not as effective as birth control pills. The app will not work the same in preventing pregnancy for everyone who uses it, cautions Erin Brodwin in Business Insider. It's based on an algorithm that measures women's body temperatures, cycle irregularities, sperm survival and other issues related to ovulation and fertility. However, this fertility-awareness-based method of contraception is not as reliable as the pill because the human body is not always reliable, says Brodwin.
