The Bump’s free pregnancy app is the most loved baby and pregnancy tracker for expecting and new parents, providing features you won’t find on other baby apps:


The Bump is the original home of the cute fruit.

Prepare to smile and look forward to each week: The Bump compares baby’s growth in utero to beautifully illustrated produce (“Baby Is As Big As a Peach”) in a way that’s fun and easy to share with friends and family.

Discover comprehensive updates about the changes and developments happening to both baby and your body while you’re pregnant, and learn how best to plan ahead.

From name length and style to country of origin and meaning, you’ll find baby’s name in one of The Bump’s specially curated lists.

See an exciting and exclusive 3D interactive visualization of baby's week-by-week growth. Interact and learn new facts about baby like never before with the next step in baby growth trackers.

Every day, the award-winning editorial staff of The Bump delivers fresh and relevant content for your specific week of pregnancy. The articles are timely and comprehensive: always know what’s safe and standard; find out how to ward off morning sickness; learn the best things to pack in your hospital bag; and discover the best prenatal workouts for you.

The Bump’s comprehensive suite of helpful tools makes it the versatile free baby app for you. Stay up to date on you and baby’s progress with invaluable tools like the pregnancy countdown tool, baby growth tracker, a due date calculator, a kick counter, a pregnancy weight gain tracker, and a contraction counter to determine when it’s time to enact your birth plan. And the Bump’s food safety tool provides nutritional guidance and helpful information throughout your pregnancy.

A feature that equips every expecting mom with important information about their prenatal doctor visits. It suggests questions to ask your doctor and integrates appointments seamlessly with your mobile phone's calendar.

The Bump is solving two of Baby Registry’s biggest challenges:

+ The Bump has collected the top registry products across Amazon, Target, Walmart and so much more, complete with reviews from parents who’ve been where you are. This registry has only grown over time, so you can be sure you’ll find everything you want and need.

+ The typical mom-to-be will register at two or more stores, because there are always some items that require a special, secondary registry. When it comes to managing multiple registries, the Bump has you covered. The Bump will automatically track your registries across each retailer, so you can keep tabs on what you’ve registered for, what’s been bought and what’s still waiting on your registry.

Document your pregnancy by creating a weekly album of your happily growing belly. And once baby is born, the album expands to track their first amazing year in the world.

The Bump team reads every email, answers each phone call and takes all of your reviews to heart.

Great app, but these comparisons are bonkers

So my wife and I have been using this app to track the baby’s growth, learn about our pregnancy, and try to be the best first timers we can be. However, these baby size comparisons are absolute bonkers. From endive to kiwi, cabbage to lettuce? A ball fruit to a long fruit? Week over week these size comparisons are wild and so out of left field. Like I get that they are “standard/average” but like we all know there’s like 3 to 4 popular heads of lettuce? Romain is different than green leaf which is different than iceberg. All of them differing in both shape, size, and weight. In the first trimester, the baby gets compare to endive. Have you seen endive? It can get huge. Also, endive can be either endive or radicchio and those are two vastly different plants. And like like orange to squash to grapefruit or something like that. I also believe there was a comparison jump from a round citrus or melon to a long vegetable. Week 18- artichoke to mango to banana to endive to coconut to grapefruit to cauliflower to kale and now lettuce. So are we comparing length or weight? And later on it’s compared to asparagus??? At 16.2 inches long? I’ve seen asparagus that long- BUT I’ve been a professional chef. Asparagus in a store that large is RARE. but again, length or weight??

The app has been very informative for a lot of things, but the size comparison is UNHINGED. Very entertaining, and not consistent or regulated at all.

Favorite app! Love the new update too!

It’s so approachable, comprehensive and educational. I feel so informed with everything that is happening along the way. A lot of times, a new symptom will develop and I’ll open the bump app and it just happens to be what one of the daily articles is about! Everything is so on point and relevant. You get the cute “fruit” size updates, week by week informational updates on what to expect, daily articles, appointment calendar, weekly checklists on things that will probably be coming up soon or things to get done, 3D views on what baby looks like and what’s developing that week, plus 3D view of what is happening inside your own body as well! There’s forums, and the new update that immediately says how far along you are and how many weeks to go is great! I truly love this app for pregnancy and feel very lucky to have found it. I don’t feel “lost” or filled with unending questions, instead— I feel as in control as possible during pregnancy! Highly recommend.

I really love this app. Now, do I love it because it continuously reminds me that I’m going to become a grandmother or because it’s a solid place for information and resources? Lemme say, it’s BOTH!! I will say I also have another app download that I had to pay a tiny fee for. But what I wish this app had (that the other does) is a place to upload my pics of my daughter’s growing belly. And whatever other pictures I decide I want to keep on the app. This app does allow you to make changes to I absolutely appreciate The Bump’s consistent flow of both daily changes and weekly changes as they’re are a lot of fun. My daughter, my mother (who will become a great grandmother), and myself almost have a daily race to see who gets to the app first upon awakening, so that we can be the first one of the day to send a .gif to our group message about which item the baby is to be compared. Like today my daughter is 16 weeks along and this week’s comparison of the Bebe is the size of an avocado. The daily fact today is that Bebe is the size of a chipmunk (minus their tail)! Always so cute. So now I’m ~24 weeks away from becoming a grandmother to a Capricorn Bebe. 🥰
