Amazing App

Love this app, now using it for the second time! However, the formatting in the articles seems to have gone a little awry in the latest couple of versions compared to when I used it a couple of years ago.

Life’s surprises

What to expect when expecting. It greats facts and up to date info. Easy to use and to the point.

Stellar

Love this app. Very informative. Used it for my first kid.

Helpful information, but really passive aggressive comments

The information given is definitely helpful and definitely will help out some dads who need it. But, some of the comments made about the moms-to-be are simply unnecessary and passive aggressive.

Week 25: “your partner might notice that her hands and feet are getting a little swollen lately. This is very common in pregnancy . . . Don’t tell her she’s looking less like a human and more like a balloon animal.”

I get that it’s trying to be funny, but does the creator of this app think all men are idiots and would actually need someone to tell them to not insult their wife/partner? I don’t understand why that’s necessary.

Super Helpful App - First Time Dad

Love the app so far, it’s very insightful and the objects used to compare measurements crack me up! I do wish there was an option to convert the measurements for those of us who don’t use the metric system within the app.
