Smartphone聽apps聽generally make all of our lives a little easier, right?聽They can聽help you save money while encouraging you to shop (where do we sign up?), do your laundry聽and even calm your anxiety. And many women also use their smartphones to track and plan a very, very important part of life: pregnancy. But can you trust these apps when you鈥檙e trying to get pregnant鈥 or trying not聽to get pregnant?聽A new study of almost 100 smartphone fertility apps says 鈥 for the most part 鈥 absolutely not.

Researchers at Georgetown University Medical Center found that most of the apps they studied didn鈥檛 actually use evidence-based, scientific methods for predicting fertility. Yikes. They studied 95 apps, and found that 55 of those didn鈥檛 actually claim to use evidence-based methods (hey, at least they鈥檙e not lying to you?).


Then the researchers tested the remaining 40 apps and found that of those, only six had perfect scores in terms of accurately predicting fertility days. Those apps were Ovulation Mentor, Sympto, iCycleBeads, LilyPro, Lady Cycle and MyNFP.

The researchers warn specifically against using many of these apps to聽avoid聽pregnancy. 鈥淪martphone apps are increasing in popularity because more and more women are interested in using natural or fertility awareness-based methods of family planning鈥 They want to feel empowered with greater knowledge of their bodies,鈥 says Marguerite Duane, a family physician who led the study. But the smartphone method gets more than a little risky when the apps you鈥檙e using aren鈥檛 actually based on science.


The bottom line: 鈥淲hen 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 (note: the six apps listed above),鈥 says聽Marguerite.
