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 it. 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!
