When couples find out they're expecting, one of the things they can count on is that everyone will want to guess whether they're having a boy or a girl. But of course, no one ever actually has any control over it ... or do they?

A new app called StorkDiet/Girl claims that it can help people conceive baby girls, all for the price of $9.99. So does it really work?

Creator of the app Alain Hanash used data from a study conducted by two British universities that tracked the diet of 740 pregnant women. It concluded that 56 percent of the women who followed low-sodium, low-calcium diets had baby girls. Banking off those results, the app creates a "natural and scientific based" nine-week diet for women hoping to give birth to a daughter. The creators of the app claim to have an 81 percent success rate.

But can you really determine your baby's sex from an app? Scientists say the evidence surrounding the concept that a certain diet can affect your child's gender is inconclusive. And even if it wasn't, they warn parents-to-be that nothing, including this app, is ever 100 percent guaranteed so it's best not to get too attached to the idea of having either a girl or a boy.

Call me a skeptic, but I have to side with the naysayers on this one. Whatever happened to just leaving it up to fate and then counting your lucky stars for the child you have? I mean, there's nothing wrong with wanting one particular gender, but it's important to be realistic about the odds and especially about these random techniques that claim to sway your luck one way or the other. After all, centuries of experience have shown us that gender is pretty much all about biology and timing.

Still, for those women who REALLY want a girl and are desperate to try this app, I hope they at least run the diet by their doctor beforehand. Safety first, right?

And no matter what side you fall on, I definitely recommend checking out these seven  super helpful apps that can help women keep track of their pregnancy:
