What the developer says changed (the verdict above weighs this against what reviewers report):

Every month we fine-tune The Bump to improve speed and reliability

Recurring themes

Technical Glitches negative
Many users report frequent app freezing, crashing, slow loading times, and specific features (like 3D models or trackers) not working or displaying correctly. This directly contradicts the developer's claim of improving speed and reliability.R6R14R21R22
Account Issues negative
Users frequently experience being logged out of the app, difficulty logging back in, and sometimes the loss of previously entered data, which is highly frustrating. One user even reported another couple's information populating their account.R5R17R22R30
Informative Content positive
A core strength of The Bump is its comprehensive and detailed information on pregnancy, baby development, and maternal changes. Users appreciate the weekly updates, articles, and tips, finding them helpful and reassuring, especially for first-time parents.R3R8R12R15
Content Accuracy & Bias negative
Several users express concern over the accuracy of information (e.g., inconsistent baby size comparisons, outdated science) and perceived biases in articles, particularly regarding gender terminology, use of 'pregnant people' instead of 'women,' and a focus on hospital births.R4R6R7R23
User Experience & Design mixed
While many find the app easy to navigate and visually engaging with 3D models and size comparisons, some find the interface cluttered, articles generic, or wish for more tailored content for subsequent pregnancies or non-US users.R8R13R26R44

Who it's for

The Bump is for expectant parents, especially first-timers, who are looking for a free, comprehensive guide to pregnancy and early baby development R18R73. It's also suitable for family members like grandparents who want to follow along R10. Users who prefer a less cluttered experience, require specific features for multiples, or are sensitive to certain language choices might want to skip it R13R23.

Evidence note: The recent reviews show a significant increase in negative feedback regarding technical issues and content concerns, which contrasts with the high lifetime rating. This suggests a recent decline in app quality or user satisfaction, despite the developer's notes claiming improvements.

  1. [R3] 5/5 · US Great milestone information: This will be my third pregnancy using this app. I learn so much throughout the pregnancy and it keeps me on track. I love being able to look at milestones with my first child.
  2. [R8] 5/5 · US Amazing pregnancy app!: I didn’t expect an app to make pregnancy feel this organized and actually exciting, but The Bump really does. From day one, it’s been like having a calm, helpful guide in my pocket. The weekly updates are my favorite, they’re detailed but easy to understand, and I love seeing how my baby is growing in a way that actually feels real. The visuals, the size comparisons, the li
  3. [R12] 5/5 · US So informational!: I’ve loved this app all of pregnancy and for each week of my baby after being born! I’ve learned so much and it’s been very reassuring.
  4. [R15] 5/5 · US Enjoyable: Very helpful and straight forward with every information...loving it so much😍😍😍
  5. [R26] 5/5 · US Friendly and informational!: It’s been 15 years since I’ve given birth, so all of the resources in those app were so fun to read about this pregnancy! Also, the 3D growth tracker, daily facts, etc were extremely helpful and made this pregnancy very special.
  6. [R44] 5/5 · US THE MOST AMAZING INFORMATIVE BABY APP YOU’LL EVER NEED: This app is Free, and for any Mom at any stage of Pregnancy. It has 3D Interactive features to see the growth and daily milestones of your Baby growing in your Bump. It is loaded with info. Even my Doctors were thoroughly impressed.. I am grateful for all the available features on it at no cost, especially due to having been out of work f
  7. [R59] 3/5 · US Auto Log out: I like the app for articles and the 3D imaging of the fetus development each week, but it logs me out automatically at times. Like many people, I’m can’t keep track of all of the logins I have, so it’s a big hassle to try to log back in. I also don’t like the community chat layout. It’s hard to navigate. The one in Ovia is better.
  8. [R10] 5/5 · US I’m the grandmother to be: You forget even after three children so this has helped me remember all those things as I follow my daughter’s pregnancy I sure wish I had this one I was expecting.
  9. [R18] 5/5 · US Love it: Being a first time, mom this app is super helpful
  10. [R20] 5/5 · US First time father: This app really helped me and my wife with our first baby
  11. [R73] 5/5 · US Brought some peace of mind: The checklist feature is amazing! Breaks down all of the to-dos by trimester and week, with articles and resources to accomplish them. Invaluable for a first time mom.
  12. [R11] 5/5 · US Amazing free resource: Thank you for offering this information for free! It’s so helpful and surprising to find free support online these days! Great ap with loads of resources
  13. [R40] 5/5 · US It’s real free: Great app and doesn’t want you to pay to share any article etc.
  14. [R50] 5/5 · US App review?: I love this app and I like how it dosent have adds, and showing what’s happening to mom and baby is very helpful and wholesome.
  15. [R19] 3/5 · US Love the app, hate the glitches: I love the feeding tracker but the timer frequently jumps numbers and sometimes even after I’ve paused one side and started timing the other breast, the timer will run on both breasts. And of course it always happens at night when I really don’t feel like dealing with anything extra. I’ve tried closing the app and restarting it but this doesn’t always fix the issue
  16. [R24] 5/5 · US Great!: Sometimes my app freezes. But I love that there are so many resources all in one place. And there is even a spot for discount codes for certain websites! :)
  17. [R81] 5/5 · US Love the articles!: Being a first time mom this app is so helpful! It keeps everything in one place from weight tracker to photos and keeps me informed each step of the way. Only a few weeks in but loving this app!
  18. [R6] 1/5 · US Glitches & Inaccuracy: It will glitch often and you’ll be stuck at the Home Screen. Also refers to breast feeding as “chest feeding” and calls us women “pregnant people”
  19. [R14] 4/5 · US Fun app for tracking baby’s development: I love reading about my baby’s development each week. That said, this app can be super buggy. For example, when I click on the “3D” model of baby, it never takes me there, and I have to try several more clicks to get it to load. There also have been some errors in content, such as listing baby’s weight in oz when it should clearly be pounds. But overall, I
  20. [R21] 4/5 · US Keeps freezing: App keeps freezing when I am on it or takes forever to load when I open it :(
  21. [R22] 2/5 · US Not good anymore: Feels like the developers and owners abandoned it or something. A bunch of features are buggy or don’t work at all (like the 3D models), I’m regularly logged out and have to find my login info. It doesn’t update unless I force a restart, so I regularly open the app and get the wrong number of weeks which is the #1 thing the app is supposed to do: say how far along we are! Why doe
  22. [R17] 1/5 · US Need to fix: The app keeps logging me out, which is really frustrating. Also all the journals disappeared when it upgraded automatically and no where to be found.
  23. [R30] 1/5 · US Deleted all of my data from feeds, pumping and diaper changes: Logged me out for no reason and when I logged back in all my data from the first two weeks of my child’s life was erased. So frustrating.
  24. [R34] 2/5 · US Disappointing: Used it for my first pregnancy and it was great, never had any issues. 2 years later when I tried to add my second pregnancy I’ve had nothing but issues. Won’t properly display baby’s nickname (just blank), logs me out frequently, and error messages saying it can’t load data every other day. Never had a single one of these issues with my last pregnancy and thinking I will just delet
  25. [R4] 1/5 · US Annoying: I got this app and thought it was helpful to have while tracking my pregnancy. Until I clicked on an article that discussed learning about the gender of the baby. Within the article it had a whole paragraph describing how gender and sex are different terms. Which, is not biologically true nor was this ever true. This type of agenda should not be pushed within articles on pregnancy tracki
  26. [R7] 3/5 · US It’s just ok: I like that it gives daily updates of how big baby is but it gets very confusing. For example, I’m 12 weeks and baby is supposed to be the size of a lime, however on like the daily facts it says that the baby is as long as the diameter of a golf ball. Those are two VERY different sizes. This is my first baby and if I have a second I probably would not download this again.
  27. [R23] 2/5 · US So Liberal: A “pregnant person” is a woman…. Just say woman.
  28. [R2] 5/5 · US Bug: Manual input doesn’t work
  29. [R13] 4/5 · US Love it: I seriously love this app, it’s a very handy tool for so many different things. The one thing that I wish it had was more about twins. It allows you to select that you’re having twins in the set up, but doesn’t show two babies in the 3D images, there are also not as many twin articles. That said, still the best tracker app I’ve found thus far.
  30. [R66] 2/5 · US Minimal useful info: The weekly symptom information is good, but it’s hard to parse through between the dozens of trashy articles they recommend you read each week that all read like bad buzzfeed posts. I prefer the apps that stick more with pregnancy information and not with clickbait articles.
  31. [R223] 2/5 · US Sometimes fun, mostly generic: Most of the information given is generic information you can find on Google or from reading one book. I found talking to my doctor and other mothers in my life more helpful. They try to have articles on relationship advice and navigating changes during pregnancy, but it is too generic to be of much use. However, this makes sense because so many people use the app. Th
  32. [R294] 3/5 · CA The best one so far: It's pretty great! I keep coming back to it almost every day. Docking one starts for US-centricity (at least do metric units hey) and another for the profusion of covert advertising. More information less ‘buy this buy that’ please
  33. [R5] 1/5 · US Another couple’s info populated in my account: I just downloaded this app a few days ago and didn’t spend too much time looking around until today. I noticed that the initial in the top right corner that indicates the user’s name didn’t match my first name, so I went into the account details. Another person’s full name (not in any way related to my own) is in the “My Account” fields, and another f
  34. [R36] 1/5 · US Glitch: Usually love this app and am using it for baby #3. Last week it glitched and from week 17-18 I switched from a pomegranate to an avocado and went from like 5 inches to over 8 inches. My other kiddos ask every week what size the baby is and I have to keep telling them it’s not working 😔 please fix it!
  35. [R62] 4/5 · US Accuracy: The app is great overall I love watching the progress but the fun facts aren’t always correct. This app needs to work on its accuracy and that’s it, I would recommend this app to any new moms!
  36. [R438] 3/5 · CA Good app, but should consider multiples!: I’ve always liked the bump app since my first born, but this time I am pregnant with twins and I wish there was a multiples feature. Multiples are on the rise and it would be nice to add this.
  37. [R440] 2/5 · CA Not for Canadians Or second time moms: I liked this app for my first pregnancy. This time around I barely glance at it. It’s very American focused (I.e check if you get FMLA! Call your health insurance company). And it is very much focused to first time parents. It would be nice if the developers could program articles, tips, etc for when it’s your second or third baby. I’m looking for a different
