From banking to chasing Pokemon, smartphone apps have undoubtedly changed the way we live our lives. But new research suggests using phone apps to help get pregnant - or avoid it - could be highly unreliable.
A study of 95 smartphone fertility apps conducted out of Georgetown University Medical Center in the US found more than half don't actually use evidence-based, scientific methods to generate their information. However, it should be noted that they also don't claim to, which is a reminder to read the fine print.
Of the remaining 40 apps, the study found on six perfectly predicted the days a woman was fertile.
Those apps were Ovulation Mentor, Sympto, iCycleBeads, LilyPro, Lady Cycle and MyNFP.
Researchers involve are warning women against using fertility apps as a form of contraception, especially when there is little science involved.
"Smartphone apps are increasing in popularity because more and more women are interested in using natural or fertility awareness-based methods of family planning… They want to feel empowered with greater knowledge of their bodies,” says Marguerite Duane, a doctor who led the study.
"When learning how to track your fertility signs, we recommend that women first receive instruction from a trained educator and then look for an app that scored four or more on mean accuracy and authority in our review (which are the six apps listed above).”
