Best Pregnancy Apps
The best pregnancy apps split into two camps: free trackers with 3D videos and a community, or a private planner that keeps your data on your own device.
If you want one free app to carry you through the whole pregnancy, What to Expect is the most popular choice, because it pairs daily week by week updates with the largest built-in community of parents. If you would rather keep your appointments, symptoms, weight, registry and baby names in one calm place that has no ads and no account, PregnancyOS is a $23 one-time HTML file that stores everything on your own device. And if your priority right now is the registry, The Bump links directly to products at Amazon, Target and Walmart so you can build and share a list fast.
| Tool | Best for | Price | Subscription | Works offline |
|---|---|---|---|---|
| PregnancyOS | A private, all-in-one planner you own | $23 one-time | No | Yes |
| What to Expect | Free tracking plus a huge community | Free, ad-supported | No | No |
| BabyCenter | Free tools, kick counter, contraction timer | Free, ad-supported | No | No |
| The Bump | Building and sharing a baby registry | Free, ad-supported | No | No |
| Pregnancy+ | 3D baby models and expert courses | Free plus premium | Optional | No |
| Ovia Pregnancy | Detailed tracking, often via an employer | Free, premium via sponsor | Via sponsor | No |
Why the choice really comes down to two things
Almost every pregnancy app does the same core job: it tells you how far along you are, shows the baby’s size as a fruit or a vegetable, and serves you an article for the week. The mainstream apps do that well and for free.
The two things that actually separate them are community and data. If you want thousands of other parents due the same month to talk to at 3am, a cloud app with forums is the right tool. If you would rather your appointment notes, weight, symptoms and the names you are secretly considering never sit on a company’s server, a local planner is the right tool. Most of this guide is helping you decide which of those two you care about more.
1. PregnancyOS - best for a private, all-in-one planner you own
PregnancyOS is a single HTML file you download and open in your browser. There is no account, no login and no cloud. Everything you type is saved in your browser’s storage on that device, and Ecuato never receives it, because nothing in the file sends it anywhere.
It is organized as one calm dashboard with clear tabs. Today shows your trimester, how many weeks along you are, a baby-size comparison, your next appointment and the day’s stats in one snapshot. Details holds your due date, last menstrual period, provider, hospital, delivery preferences and personal notes. Appointments tracks upcoming and past visits with provider notes and follow-ups. Symptoms is a daily log that includes mood and energy alongside how you physically feel. Weight charts your gain against an expected range so you can see the trend rather than a single number. Registry lists baby items with a budget, a priority and a got-it, need-it or gifted status. Hospital Bag is a pre-packed checklist you tick off. Questions is a running list of things to ask your provider. Names keeps a shortlist of girl, boy and gender-neutral names with meanings and a simple voting system for you and your partner.
It costs $23 once, with no subscription, no renewal and no expiry. It opens on a laptop, adds to the home screen on iPhone via Safari or Android via Chrome, and works fully offline after the first load.
Where it loses, honestly: there is no community, no 3D fetal videos, no kick counter and no contraction timer, and it does not send reminders. Because your data lives on the device, backing it up is your job, and clearing your browser data clears the planner. It is a record you keep and control, not a service that pings you. If you want the social side or the labor-day tools, pair it with one of the free apps below.
2. What to Expect - best free all-in-one tracker
What to Expect, from the team behind the long-running book, is the default free pregnancy app for a reason. It combines daily educational updates, symptom tracking, baby growth, fun size comparisons and one of the largest parent communities in any app. If you want company through the whole journey without paying, this is the strongest single pick.
Where it loses: it is free and ad-supported, so the interface carries banner ads and sponsored content, and it is owned by Everyday Health, which has been reported to share user data with third parties. Read its privacy policy and decide how much that matters to you. The community, while huge, can also be noisy.
3. BabyCenter - best free toolset, including a kick counter
BabyCenter is completely free and unusually tool-rich. Beyond week by week content and 3D development videos, it bundles genuinely useful trackers: a kick counter, a contraction timer, a due date calculator, an appointment and symptom calendar, and a registry checklist. If you want those specific labor-prep tools without paying, BabyCenter covers them.
Where it loses: like What to Expect, it is owned by Everyday Health, is ad-supported, and has faced the same reporting about data sharing. It is a broad, busy app rather than a focused planner, so organizing your own pregnancy inside it takes some discipline.
4. The Bump - best for building a baby registry
The Bump, from The Knot Worldwide, is the registry-first app. It does the usual countdown, baby growth visuals, a kick counter and a contraction timer, but its standout is a registry that pulls products from Amazon, Target, Walmart and more, with parent reviews, so you can build and share one list across stores. For the registry stage, it is hard to beat.
Where it loses: the shopping focus means more product placement, and as a free app it monetizes through those retail links. As a general day-to-day tracker it is capable but not especially deep.
5. Pregnancy+ - best for 3D models and structured courses
Pregnancy+, made by Philips, is one of the most downloaded pregnancy apps in the world. The free tier is generous: interactive 3D models of the baby’s development, a size guide, daily articles, a hospital bag planner, a birth plan, a kick counter, a weight log and a contraction timer. A Premium subscription adds video and audio courses led by maternal health experts.
Where it loses: the richest educational content sits behind Premium, and like every app here it is a cloud service that needs a connection. If you only want the trackers, the free tier is plenty, but you will be nudged toward the paid courses.
6. Ovia Pregnancy - best detailed tracker, often through an employer
Ovia is a polished, data-rich pregnancy tracker with detailed symptom and health logging. Many people get its premium features free because their employer or health plan sponsors it. Importantly, as of mid 2025 Ovia stopped showing ads to consumer users and says it no longer sells or shares personal data for advertising, which is a meaningful change from its earlier reputation.
Where it loses: the employer-sponsored model is exactly why Ovia drew years of privacy criticism, since sponsors can see aggregated, de-identified trends about their workforce. Ovia says it does not share your individual health data with an employer unless you opt in, but if the idea of a workplace-linked pregnancy app bothers you, that is a fair reason to look elsewhere. It is also still a cloud account, so your data lives on their servers.
How to choose
- Pick PregnancyOS if you want one calm planner for appointments, symptoms, weight, registry and names, and you want that data to stay on your own device for a single $23 payment.
- Pick What to Expect if a large, active community matters most and you are fine with a free, ad-supported app.
- Pick BabyCenter if you want free labor-prep tools like a kick counter and contraction timer bundled with week by week content.
- Pick The Bump if your immediate task is building and sharing a baby registry across several stores.
- Pick Pregnancy+ if you love the 3D development models and want optional expert-led courses.
- Pick Ovia if your employer sponsors it, or you want its detailed tracking and are comfortable with a cloud account.
What a pregnancy app can and cannot do
A pregnancy app is an organizer and a diary, not a monitor and not a clinician. Its real payoff is small and practical: you walk into a 15-minute appointment with your weight trend, your symptoms and your questions already written down, so you use that short window well. Before you have your own data, our free due date calculator and pregnancy weight gain calculator give you a starting point with no signup, and if you are still in the trying stage, our guide to the best ovulation and fertility tracking apps covers that earlier chapter.
One thing worth saying plainly: none of this is medical advice, and no app on this list can tell you whether something is normal. If a symptom worries you, if movement changes, or if anything simply feels off, that is a call to your provider, not a search in an app.
Frequently asked questions
What is the best pregnancy app?
For a free all-in-one tracker with week by week updates and a large community, What to Expect is the most popular pick. If you want a calm planner that keeps appointments, symptoms, weight, your registry and baby names in one place without ads or an account, PregnancyOS is a $23 one-time download. If your main job right now is building a baby registry, The Bump links straight to products at major retailers.
Is there a pregnancy app with no subscription?
Most mainstream pregnancy apps are free to download, and several add an optional subscription for courses and extra content, such as Pregnancy+ Premium. PregnancyOS takes a different route: one $23 payment, no subscription, no renewal and no account. What to Expect, BabyCenter and The Bump are free and ad-supported, so you pay with attention rather than money.
Which pregnancy app is the most private?
Free pregnancy apps run on servers and, being ad-supported, often share data with third parties, which is a documented concern for this category. PregnancyOS is the private outlier because it is a single HTML file with no server: everything you type is saved only in your own browser on your own device, so there is nothing to transmit, sell or leak. Ovia stopped selling or sharing consumer data for advertising in mid 2025, which is a real improvement, but it still stores your data in the cloud.
Do pregnancy apps work offline?
The app-store apps need a connection to load content, sync and show ads, though most let you log an entry and sync later. PregnancyOS works fully offline after the first load because the whole planner lives in one file on your device. That is useful on a plane, in a clinic basement with no signal, or anywhere you would rather not be online.
Does PregnancyOS have a kick counter or contraction timer?
No. PregnancyOS focuses on planning: your due date and details, appointments, a symptom and weight log, a budgeted registry, a hospital bag checklist, questions for your provider and a baby name shortlist. If you want a kick counter or a contraction timer for late pregnancy and labor, the free apps such as BabyCenter and Pregnancy+ include those, and you can use one alongside the planner.
Can I use PregnancyOS on my phone?
Yes. It opens in any browser on a laptop, and on a phone you add it to your home screen from Safari on iPhone or Chrome on Android, where it behaves like an installed app. It is one file, so the same planner works across your devices, though your entries stay on whichever device you typed them on rather than syncing between them.
Is a pregnancy app a substitute for prenatal care?
No. Every app and planner here is a tracker and an organizer, not medical advice and not a monitor. Their real value is walking into an appointment with your symptoms, weight trend and questions already written down. Anything that feels wrong is a reason to call your provider, not to open an app.
