# ProbaBaby vs What to Expect: Which Pregnancy App Wins in 2026? _The community-driven veteran versus the privacy-first newcomer. Here's how they actually compare._ - Source: https://proba.baby/en/compare/probababy-vs-what-to-expect - Language: English - Last verified: v1.0.4 · 7 Sep 2026 - Last updated: 2026-09-05 What to Expect is the app companion to the famous book series. Its biggest strength is community: the forums are the largest and most active in the pregnancy-app category. Its biggest weakness is that the app itself leans heavily on content and ads, with shallow tracking and zero iOS-native polish. ProbaBaby comes at the same problem from the opposite direction. There are no forums. There are no ads. There's a working contraction timer with Live Activity, an Apple Watch app, an interactive hospital-bag checklist, real genetics-based predictions, and offline-first storage of sensitive data. If you want to read other people's stories and discuss them, What to Expect is the better choice. If you want to track your pregnancy with serious tools and keep your data to yourself, ProbaBaby is. ## Picks - **Best Overall: ProbaBaby** — Working modern app: ad-free, Apple Watch + Live Activities + Dynamic Island, real genetics predictions, 30+ in-app free tools. - **Best for Forums: What to Expect** — What to Expect has the largest active community in the pregnancy-app category — best if you want to read and post with other parents. ## Feature comparison | Section | Feature | ProbaBaby | What to Expect | | --- | --- | --- | --- | | Pregnancy Tracking | Week-by-week timeline | Yes | Yes | | Pregnancy Tracking | Daily content / tips | Yes | Yes | | Pregnancy Tracking | Twin & multiples pregnancy mode | Yes | Partial | | Pregnancy Tracking | Track twins after birth (multi-baby) | Yes | No | | Pregnancy Tracking | 3D fetal model | No | No | | Health & Symptoms | Symptom logging | Yes | Partial | | Health & Symptoms | Mood tracking | Yes | No | | Health & Symptoms | Weight tracking + trend | Yes | Partial | | Health & Symptoms | Sleep tracking (pregnancy) | No | No | | Birth Prep | Hospital bag (interactive) | Yes | Partial | | Birth Prep | Birth plan builder + PDF | Yes | Partial | | Birth Prep | Contraction timer | Yes | Yes | | Birth Prep | 5-1-1 rule alert | Yes | Partial | | Birth Prep | Kick counter | Yes | Partial | | Tools & Calculators | Due date calculator | Yes | Yes | | Tools & Calculators | 30+ in-app free tools | Yes | Partial | | Tools & Calculators | Genetics-based predictions | Yes | No | | iOS Native Features | Apple Watch app | Yes | No | | iOS Native Features | Live Activities | Yes | No | | iOS Native Features | Dynamic Island support | Yes | No | | iOS Native Features | Home Screen widgets | Yes | Partial | | Privacy & Data | No ads | Yes | No | | Privacy & Data | Offline-first storage | Yes | No | | Privacy & Data | Doctor-ready one-sheet PDF reports | Yes | No | | Pricing & Localization | Free tier | Yes | Yes | | Pricing & Localization | Languages supported | 32 | 3 | | Pricing & Localization | Turkish (Türkçe) | Yes | No | ## Methodology We installed What to Expect on a test iPhone alongside ProbaBaby in May 2026 and used both daily for two weeks. We logged the same symptoms, packed the same hospital bag, ran each app's contraction timer, and explored every free tool. Ratings use the same scale across all our comparison pages: ✓ full (present and well-built), – partial (limited, shallow, or paywalled), × none. Some rows show values (price, language count) instead of a rating. What to Expect leads on community size and brand familiarity (it's the app for the book series). ProbaBaby leads on tracking depth, iOS features, ad-free experience, and privacy. If you want forums and content, choose WTE. If you want a working tracker that respects your data, choose ProbaBaby. Pricing and feature availability are checked at publish time. We update this page when What to Expect ships a new version. ## Disclosure ProbaBaby is the publisher of this comparison. We do not accept payment, affiliate commissions, or sponsorships from What to Expect. The App Store link in our card points to ProbaBaby's own listing; the link in What to Expect's card goes directly to their App Store page with no tracking. ## FAQ **Is What to Expect free?** Yes, with ads — and the ad load is heavy. An optional Premium subscription removes ads. ProbaBaby is free without ads at any tier; only AI baby predictions are paid. **Does ProbaBaby have a community/forum?** No. ProbaBaby is built around tracking and tools, not user-generated content. If active forums are important to you, What to Expect is the better fit. Many parents use both: ProbaBaby for tracking, What to Expect for forums. **Which has better tracking?** ProbaBaby. What to Expect's tracking is shallow — limited symptom logging, no Apple Watch, no Live Activities, no doctor-ready PDF reports. ProbaBaby treats tracking as the core product. **Can I use both apps together?** Yes. Many parents do — ProbaBaby for personal tracking and tools, What to Expect for community and reading. The two don't sync, so any tracking you do in one stays in that app. **Which is better for partners?** ProbaBaby. What to Expect doesn't really support partner participation. ProbaBaby has explicit Dad, Grandparent, and Caregiver roles with real-time sync and assignable checklist items. **Which is better for twins?** ProbaBaby — What to Expect has no way to set a twin pregnancy in the app. In ProbaBaby you mark twins or triplets on your pregnancy profile and get delivery-window guidance adjusted for multiples in your doctor visit summary, twin-specific weight-gain targets, and a hospital bag that scales to your baby count. After birth, each twin gets independent tracking, free. ## Sources - App Store listings for each app — Pricing and feature availability verified May 2026: https://apps.apple.com - FTC: Flo Health, Inc. settlement (2021): https://www.ftc.gov/news-events/news/press-releases/2021/01/ftc-finalizes-order-flo-health-period-fertility-tracking-app --- ProbaBaby (listed on the App Store as “Pregnancy & Baby Tracker - PB”) is a free iPhone, iPad and Apple Watch app for pregnancy, newborn and postpartum tracking, built for twins, in 32 in-app languages, with an optional AI baby-face prediction that computes Mendelian genetics (Punnett squares) from the traits you enter before any image is generated.
