## What is Big Daddy?

The Big Daddy – The Pregnancy App for Dads

Becoming a dad? You’ve got this.

The Big Daddy is the definitive modern pregnancy app built specifically to help fathers-to-be feel confident, help their partner and prepare for their baby. Get high quality, clear, practical, real-doctor guidance so you can support your partner, understand your baby’s development, and feel confident from week 1 to birth day. We don't need your email address so we don't ask for it; everything is private and secure, and stays on your phone. 

We're introducing the Bumpie(TM) - take weekly photos of your partner with our custom photo app that allows you to align and overlay previous photos for pro-level timelapse videos showing the baby growing - the ultimate pregnancy keepsake! Add in our home screen widget, contraction timer, baby decoder and our own name dictionary, this is pre-Dadding at the next level.

### 4/5 — Amazing App

*2026-04-15*

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.

**Developer response:** Hi - congratulations on Bump 2! 

So glad that you love the app. If you could possibly email us on info@thebigdaddyapp.com with some more information about the formatting issue that would be amazing, so that we can get it fixed. Thanks!

### 5/5 — Life’s surprises

*2024-10-29*

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

### 5/5 — Stellar

*2023-12-11*

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

### 3/5 — Helpful information, but really passive aggressive comments

*2023-07-14*

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.

### 4/5 — Super Helpful App - First Time Dad

*2023-02-03*

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.

### 5/5 — It’s great

*2023-01-04*

I’m only using the free version so I don’t have access to the contraction counter, hospital bag, baby checklist etc.. however this app is amazing for providing updates weekly of how baby is growing and how the Mrs is going to be feeling. It’s been really helpful to understand what is normal and what to expect as it’s all mostly explained to the mother during the midwife/doctor meetings. 

It also put things into easy ways to understand, for example, this week (29 weeks) he is the weight of a tomahawk steak, so now when the Mrs is complaining of her bump being heavy, I can get one of these on the BBQ and really relate to what she is feeling! 😂

**Developer response:** Thanks so much for your great review. There's definitely loads that you can get out of the app whether you use the free version or if you upgrade. Enjoy that steak!

### 5/5 — Big Daddy App

*2022-10-27*

It was a lot of fun to read the little articles and reminders every week. The way it encouraged me and my wife was awesome. Got some laughs out of the different comparisons it did through out the pregnancy! Recommend for any man 10/10

### 5/5 — Babies are for the Boys!

*2022-08-31*

Love this app. Helps me understand what’s going on with the Mrs and my baby. I read everything and read it to my wife too. Love all the info.

### 3/5 — Hyperemesis gravidarum

*2022-08-24*

It saddens me to see all this app offers but nothing on Hyperemesis gravidarum my wife has this incurable disease that has many asking once I tell them she is HG they ask what is it? There are a good few women who have this and it’s not talked about enough to educate people on the topic, it’s a very scary and life threatening disease to the mother and baby and I hope to see in the future more talk about this and ways to help these women who suffer through it if they even can make it through it without termination or death to the baby or mother everyday I wake up knowing I could lose one or both and all I can do is watch her suffer and i sit Idlelea by her it’s a pain I suffer knowing there’s nothing I can do to help so I hope in this review something can help change the topic of HG till then i will still be an advocate for those women in hopes of change and talk

### 1/5 — No features

*2022-06-28*

Gotta pay money to do anything with the app
