Best Overall
ProbaBaby
Privacy-first design with no third-party tracking, plus deep iOS integration that Ovia hasn't matched (Apple Watch app, Live Activities, Dynamic Island, no ads).
View on App StoreProbaBaby vs Ovia Pregnancy: Which Is Better in 2026?
Two of the most-installed pregnancy trackers, side by side. Privacy, iOS polish, and free-tools depth are where they part ways.
Ovia is the long-running incumbent in pregnancy tracking — it's been on the App Store since 2012 and has a mature daily-content rotation. ProbaBaby is newer, iOS-only, and built around a different philosophy: privacy-first data handling and deep iOS integration (Apple Watch, Live Activities, Dynamic Island) rather than corporate-health-benefit partnerships.
Both let you track week-by-week, log symptoms, and time contractions. The differences show up in the details: who owns your data, what the app does with it, and how it behaves on a modern iPhone.

How we tested
We installed Ovia 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.
The biggest functional difference between the two: Ovia is owned by Labcorp and has shipped employer-health-benefit integrations that share aggregated user data; ProbaBaby is independent, offline-first, and stores sensitive data on-device. iOS feature depth (Apple Watch, Live Activities, Dynamic Island) is the second axis where the apps diverge most.
Pricing and feature availability are checked at publish time. We update this page when Ovia ships a new version.
