Get pregnant sooner!

Get pregnant sooner! Non-intrusive and reusable way to detect your most fertile days – from a single drop of saliva!

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 self-learning algorithm 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 our team Harvard Medical School authors have also extensively studied automated detection of saliva crystals.



You can use Babyndex as many times as you want. This way, you can save a lot compared to purchasing loads of single-use hormone stripes on the market!



A 2018 study by Harvard Medical School showed that saliva test can predict ovulation with more than 99% accuracy, if complemented with automated crystal detection.



Your saliva crystallizes during your fertile days. Babyndex can help even women with irregular cycles. There is no need for months of temperature data and for complex predictive algorithms.


All you need is a high-quality ovulation microscope and the Babyndex app!

Babyndex is an easy-to-use solution that only requires a small microscope and a smartphone with the Babyndex application installed!

I tried everything already and spent a fortune on urine and blood tests to try and grasp unstable ovulation cycle. I was hesitant of saliva tests as it really doesn’t sound very convincing at a first glance, but after I read about it more, I decided to give it a try. I am amazed how well Babyndex analyzes my saliva crystals and how precise it is. I would definitely suggest this to any want-to-be parents!

We were trying to get pregnant for years so I know how important it is to understand my body. I was using saliva microscopes already but Babyndex app takes it to a new level. I like how I don’t need to guess my own interpretation but can trust the app to do its job!

The application is very polished and I like how easy it is to use. I’ve been testing it for several weeks now and it just takes a couple of minutes to perform the whole routine. First time you might be a bit uncertain, but app guides you through nicely!
