BabyCenter vs What to Expect: a plain-language comparison

The short answer

BabyCenter wins on community structure, with birth clubs organised by due date and a tracker that runs through baby’s first year. What to Expect wins on editorial depth, built on a book series in print since 1984. Both apps are free. Both are ad-supported. Both belong to Everyday Health Group, a Ziff Davis division. Neither discloses meaningful Apple Health integration, and neither ships AI features in the current version.

Before reaching that verdict, here are the seven axes used to compare them: availability and platforms, price and monetisation, Apple Health, AI, privacy architecture and record, community, and content depth.

The rest of this page is the detail behind that verdict, including the thing most BabyCenter vs What to Expect comparisons skip.

Last reviewed: 31 August 2026.

What we compared

Here is what each axis covers, stated before the verdict rather than folded into it.

• Availability and platforms. Which devices, and who can install it.
• Price and monetisation. Free, subscription, or ad-supported.
• Apple Health. Does it read, write, or neither, and what happens to the data after.
• AI. What ships, what runs it, what it can see.
• Privacy architecture and record. Where the data lives, and the documented history.
• Community. What kind of peer connection the app offers.
• Content depth. How large and how reviewed the library is.

The table below runs both apps against all seven axes. A closer read of each app follows it.

BabyCenter vs What to Expect at a glance

BabyCenter: birth clubs and a tracker through the first year

BabyCenter is free to download and use, with no subscription and no premium tier. The app is built around birth clubs, communities organised by due date that put you alongside other parents expecting the same month. Around that sit 3D fetal development videos, week-by-week pregnancy articles, and a tracker that keeps going after birth into infant milestones. What to Expect’s tracker stops at pregnancy.

Everyday Health Group acquired BabyCenter from Johnson and Johnson on 27 August 2019 (Nasdaq, 2019). Mozilla’s August 2022 Privacy Not Included review found that BabyCenter “collects, uses, shares, and even sells as much information as it seems to possibly can.” Mozilla found BabyCenter shares data with third-party advertisers for targeted behavioural advertising and gathers additional data from social media, public sources, and data brokers to build expanded user profiles (Mozilla, 2022). Mozilla reviewed all ten pregnancy tracking apps in that August 2022 cycle and every one received a warning. Read the current Everyday Health Group privacy policy before installing.

No HealthKit integration is disclosed in the current App Store listing. No AI features are disclosed in the current version.

What to Expect: the book brand in an app

What to Expect is the app extension of the What to Expect When You’re Expecting book series, in print since 1984. The brand describes itself as reaching 91% of first-time expecting mothers in the United States (Everyday Health Group). That is the company’s own number, and it counts the books and website as well as the app. Like BabyCenter, the app is free with no subscription gate, and it runs on iPhone and Android.

The editorial core is a library of expert-reviewed articles that the app says align with ACOG, AAP, and CDC guidance, organised around the book’s week-by-week framework. It does not publish a reviewed-article count. The community is structured the same way BabyCenter’s is, with birth clubs by due date and groups by topic (App Store listing).

Mozilla’s August 2022 Privacy Not Included review found that What to Expect collects, uses, shares, and sells personal information, and that the company “admits they plan to sell personal information they collect.” Mozilla found the app may sell or transfer data to advertisers for targeted behavioural advertising, and gathers information from data brokers and social networks to build expanded user profiles (Mozilla, 2022).

No HealthKit integration is disclosed in the current App Store listing. No AI features are disclosed in the current version.

The same corporate roof

Both apps sit under the same Everyday Health Group corporate parent, and the privacy policy that governs what the company may do with your data is an Everyday Health Group policy, not a per-brand one. Everyday Health Group is a Ziff Davis division. Ziff Davis completed its acquisition of Everyday Health in December 2016. BabyCenter joined the portfolio in the August 2019 Johnson and Johnson deal and has run on the same Everyday Health data infrastructure since.

Most BabyCenter vs What to Expect comparisons treat the two as independent competitors. They are not. If the data-selling finding in one Mozilla review gave you pause, the other review says the same thing about the sister app, and both point back to one policy.

Where the two apps do differ is at the product level: community structure, content style, and whether the tracker runs past birth. Those are real differences, and they are the right basis for choosing between them.

Which should you pick?

Pick BabyCenter if you want a tracker that carries you through the first year of parenting as well as pregnancy. The birth clubs by due date are a well-established structure, and the 3D fetal development videos are a format What to Expect does not offer in the same way.

Pick What to Expect if you already own the books or read the website and want the same voice in an app. The week-by-week content draws on four decades of editorial work, and the birth clubs give you the same due-date grouping BabyCenter does.

On privacy grounds, as the section above explains, the choice is between two apps under one Everyday Health Group policy. Read that policy before installing either. Both Mozilla reviews are linked above.

Where does myCocoon fit?

Neither BabyCenter nor What to Expect ships AI features, and both are paid for by advertising and data. If what you want is somewhere to take a question at whatever hour it lands, without that question joining an advertising profile, neither app is built for it.

myCocoon is the smallest option here by every measure that counts. No Android app, no peer community, no ads, and a smaller content library than either BabyCenter or What to Expect. It is live on the App Store for iPhone users on iOS 26 or later. The Ask assistant, the signal nudges, and the story chapters sit in a paid Premium tier; the kick counter, contraction timer, weekly content, and basic journal are free. If community or Android is the deciding factor, the two apps above are the rational choice and it is not close.

What backs up a different privacy answer is what happens to Apple Health data. myCocoon reads sleep, heart rate, steps, blood pressure, and weight from Apple Health, alongside the mood and symptoms you log in the app. Those HealthKit-derived signals live in a local-only store on your phone, set up so they never sync to iCloud or any company server.

The everyday AI runs on-device with Apple’s Foundation Models. Cloud AI is off by default. Turn it on and a defined set of pregnancy context goes to Google’s Gemini with your question: your first name and baby’s name if you have set them, your week and trimester, recent symptom names and counts, a mood trend, and a daily summary of your health signals. Leave it off and none of it leaves the phone. Anonymous crash reports and basic usage events go to Firebase; those never include health data.

Each signal gets watched against your own baseline, on its own. A run of shorter nights, a resting heart rate above your usual, a day on your feet well past your norm: any one of them can raise a quiet nudge. They are also gathered into a daily digest. Reading them together, as one correlated picture, is on the roadmap and not yet shipped.

If the privacy sections above are what you came here to resolve, that is the question myCocoon was built around. The full picture is in where your pregnancy app data actually goes.

Common questions

Is BabyCenter better than What to Expect? It depends what you value. BabyCenter wins on a tracker that continues through baby’s first year and birth clubs organised by due date. What to Expect wins on editorial depth tied to a book series in print since 1984. Both are free, ad-supported, and owned by Everyday Health Group, so on privacy grounds you are choosing between two apps under one corporate privacy policy.

Are BabyCenter and What to Expect owned by the same company? Yes. Everyday Health Group, a Ziff Davis division, owns both. Everyday Health Group acquired BabyCenter from Johnson and Johnson on 27 August 2019. Both apps operate under Everyday Health Group’s data practices, which Mozilla’s August 2022 Privacy Not Included review found include sharing and selling personal information to advertisers.

Does BabyCenter sell your data? Mozilla’s August 2022 Privacy Not Included review found that BabyCenter collects, uses, shares, and sells personal information for advertising and personalisation. The app shares data with third-party advertisers and social networks, and gathers additional data from data brokers and social media to build expanded user profiles. Read the current Everyday Health Group privacy policy before installing.

Does What to Expect sell your data? Mozilla’s August 2022 Privacy Not Included review found that What to Expect collects, uses, shares, and sells personal information, and that the company says it may sell or transfer data to advertisers for targeted behavioural advertising. What to Expect and BabyCenter operate under the same Everyday Health Group privacy practices.

Do BabyCenter or What to Expect work with Apple Health? Neither BabyCenter nor What to Expect discloses meaningful Apple Health integration in current App Store listings. If HealthKit connectivity is a priority, neither app provides it. myCocoon reads sleep, heart rate, steps, blood pressure, and weight from Apple Health and keeps those values in a local-only store on your iPhone that never syncs to iCloud or a company server.

Is there a pregnancy app that does not sell your data? myCocoon is built around that question. HealthKit-derived signals stay in a local-only store on your iPhone. There are no ads and no data sales. Cloud AI to Google’s Gemini is opt-in and off by default; when it is on, a defined set of pregnancy context and a daily summary of health signals goes to Gemini with your question. The app is iPhone-only (iOS 26 or later), smaller than either app here, has no peer community, and its assistant and signal nudges sit in a paid Premium tier.

Bottom line

BabyCenter and What to Expect are the same answer to the question of who owns them. Both are Everyday Health Group properties under one Ziff Davis parent, and both are free because advertising and data are the business model. Mozilla found both apps sell personal information to advertisers. If that is the deciding criterion, this comparison resolves before features enter the picture.

If you are choosing on features, BabyCenter’s strength is community structure and a tracker that runs past birth. What to Expect’s strength is editorial depth from a book series most obstetrician waiting rooms still stock. Neither ships AI features or discloses HealthKit integration. Both run on iOS and Android.

If you are an iPhone user on iOS 26 or later and the privacy sections above are what you came for, myCocoon is live on the App Store today. It is the smaller, iOS-only option, no Android app and no community, built so your HealthKit signals stay on your phone and your everyday AI runs on-device.
