We installed every app on a test iPhone in May 2026 and used each for a minimum of two weeks. 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. Email us if you spot an error — we update this page when apps ship new versions.
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. Three-generation analysis can reach up to 95% confidence.
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.
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.
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.
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.
ProbaBaby is the only app on this list with zero ads, no third-party tracking SDKs, 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.
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.
