Reviewers logged daily symptoms, packed a hospital bag, ran each app's contraction timer, and tried every free tool. We rated 25+ features across seven categories. For features we couldn't test directly (e.g., Apple Watch availability), we cross-referenced the App Store listing, the publisher's marketing page, and recent user reviews. Pricing was confirmed in the App Store at time of review. Ratings are: ✓ full (feature is present and well-built), – partial (feature is present but limited, shallow, or paywalled), × none (feature is absent). Some cells contain a value (price, language count) instead of a rating. Competitor data reflects observations as of May 2026 and may change.

We do not accept payment, affiliate commissions, or sponsorships from competing apps. Our App Store link points to ProbaBaby's own listing only. All other links to competitor apps go directly to their App Store listings with no tracking. ## FAQ **Why is ProbaBaby the only app here with genetics predictions?** ProbaBaby is the first major pregnancy app to ship real Mendelian-genetics baby prediction. Other apps use crowd-sourced old wives' tale predictors that are essentially coin-flips. ProbaBaby uses OCA2/HERC2 two-gene models for eye color, polygenic analysis for skin tone and height, and Punnett-square inheritance math. Premium adds a third generation — the grandparents — and confidence is capped at 95%, never 100%, because genetics never gives certainty. Scientific and Standard are two-generation. **Is Flo really a pregnancy app?** Flo is primarily a menstrual cycle tracker. It has a pregnancy mode that activates after you log a positive test, but the depth of pregnancy-specific features is shallower than dedicated trackers. Flo is best if you're already a Flo user and value continuity; not best if you want comprehensive pregnancy + birth-prep tooling. **What's the difference between What to Expect and BabyCenter?** Both are content-heavy apps backed by major US publishers. What to Expect has the larger active community forum; BabyCenter has a deeper baby module that continues post-birth. They're functionally similar — pick by the brand you've heard of in conversation. **Are there Android-friendly options on this list?** Ovia, What to Expect, BabyCenter, Flo, and Pregnancy+ are all on Android. ProbaBaby is currently iOS-only. If you have an Android phone, Ovia is the closest equivalent for feature breadth. **Which app is best for partners?** ProbaBaby supports collaborative family sharing with four roles (Mom, Dad, Grandparent, Caregiver) and full real-time sync. Hospital bag items can be assigned to Mom, Dad, or shared. Ovia and BabyCenter have basic 'partner view' modes but no item assignment. **Is there a private/ad-free pregnancy app?** ProbaBaby is the only app on this list with zero ads and offline-first storage of sensitive data. Pregnancy+ has lighter ad load than the others but isn't ad-free. Flo settled with the FTC in 2021 over health-data sharing — its privacy story is the weakest. **Do these apps work in Turkish?** ProbaBaby and Flo support Turkish. The others (Ovia, What to Expect, BabyCenter, Pregnancy+) are English-first with limited or no Turkish support. If you want full Turkish localization, ProbaBaby is the best choice. ## 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.
