Friendly app during pregnancy

I am very relieved and happy to get the best app in first shot. Since I got the good news I was looking for an app that may help us to track down the progress of my baby and the expected symptoms in moms. As I am all alone during this phase I needed an expert to validate the symptoms I am experiencing and help me out. I got a go-to-one-stop-shop for everything I needed since day 1 till my delivery.

A great app with very helpful articles. I thoroughly enjoyed using this app and have recommended to my family and friends.

Great 10/10

It’s a very informative app, as well as lovely, especially when you reach each milestones. It provides amazing tips and tricks for literally every single thing and every single week that lies ahead. I love looking through the possible symptoms you may experience during pregnancy, and reading them on here. As soon as my eyes were unbelievably dry and itchy, I instantly looked at the tips in here and found exactly what it meant and how normal it is which helps!

Fantastic app with useful features!

The app has a great design that is user friendly and well set out, with headings that clearly breakdown weekly articles regarding the gradual development of the baby. The information was concise and and reassured us as first time parents.

The only thing that would make it better would be a UK version that includes a timeline here as it differed from the US system. This is minor but would make the experience even better.
