Amazing app, always let's me know what I can expect and hasn't really been wrong yet. My baby is tracking a bit further along than it tells me to expect, but I love seeing the contrast. The app also sends me a ton of completely free samples, coupons, and gift cards which I really love and appreciate, as this is my first baby! Super happy overall.

This has been a great app to track my first pregnancy. it says the number of weeks and days you are. At the beginning of your new week, it shows you something that is the same size as the baby (you can choose if it is fruit themed, sport themed, candy themed, and I think they might have a few others). they also have an option for twins. they also give videos every week explaining how your baby is developing this week. I really enjoy it.

Can't be used on two phones apparently. My wife and I wanted to use this app, and while she's had no trouble - I downloaded it on my phone as well hoping to be able to add meals and diaper changes when she was either preoccupied or otherwise unable to add them. Every time I log in, the app says that I am in "offline mode". There's no information on how to change that. In offline mode I can see my child's account, but I'm not able to view or add any history of feedings or changes. Useless.
