How does Babyndex work?

A few days before you reach your most fertile days, changes happen to the structure of your saliva. It starts to crystalize in a different way. Using our automated application helps you interpret the saliva test and our advanced algorithms significantly increases its accuracy. Eventually, we make it faster and easier to predict when you are most likely to conceive! The saliva test is FDA-certified and beside the Babyndex team Harvard Medical School authors have also extensively studied automated detection of saliva crystals.
