The most informative app I’ve ever used

It’s been my bible, the go-to resource for understanding and reassuring that the development of my pregnancy and child is in the right direction. I recommend it to everyone I know who is expecting. It is evident from the quality and preciseness of the balanced information that the creator of this app has done a lot of research and analysis to make sure every aspect of pre & post pregnancy on weekly basis as well child growth & development on weekly & later monthly basis is holistically addressed. I am so fortunate & grateful to have come across this app. It’s a representation of selfless help lend out to mankind as a whole. Thank you for your service through this wonderful app.

Life saver!!

This app has everything you need from start to finish when it comes to babies, my favourite part is interacting with woman from around the world that are in the same boat, so to speak! Got an itch? Feel a bit funny? Haven’t felt the baby move? Putting on too much weight? Not putting on enough? Ask the hundreds of thousands of woman who can give you instant advice; support and real stories on their real life experiences. You’ve got a question, or a worry? You’re not alone and this app, and the community will show you why. 100% recommend to anyone trying to conceive, pregnant, postpartum, or just curious! Even the dads get a good look in! Favourite baby app so far!

Nice design and great community

This app has a really nice aesthetic and I love learning about the weekly changes to my body and baby. By far the best part for me is the community forum - where you are put into a group for your baby’s birth month. It has been reassuring to read and ask questions to other mamas to be, on occasions a little worrying (miscarriage posts can be anxiety inducing), but overall a resource I have really depended on so far in my pregnancy. It does tend to be very American centric, so I sometimes check the babycenter app for more Australian oriented stuff. Definitely recommend this app :)
