# ProbaBaby vs Flo: Cycle-First vs Pregnancy-First in 2026 _Flo's pregnancy mode is a bolt-on; ProbaBaby is purpose-built. Here's when each one is the right call._ - Source: https://proba.baby/en/compare/probababy-vs-flo - Language: English - Last verified: v1.0.4 · 7 Sep 2026 - Last updated: 2026-09-05 Flo became a household name by being the best menstrual-cycle and fertility tracker on the market. When you log a positive pregnancy test, Flo flips into its pregnancy mode — which is competent but shallower than dedicated trackers. There's no contraction timer. No hospital-bag tool. No birth-plan builder. Symptom and weight tracking are present but limited compared to ProbaBaby. ProbaBaby tracks cycles too — a free Planning module before pregnancy and an opt-in five-tab Period Tracker after birth, both running on one lifelong cycle history — and it is deep on every pregnancy and birth-prep feature: real Mendelian-genetics predictions, Apple Watch app, Live Activities, ad-free, 30+ in-app free tools. What it does not have is a Flo import, so switching means starting that cycle history fresh. If you're mid-pregnancy and already using Flo, continuity is reasonable. If you're starting fresh and want serious pregnancy tooling, ProbaBaby is the deeper product. ## Picks - **Best Overall: ProbaBaby** — Pregnancy-specific depth: contraction timer with Live Activity, interactive hospital bag, real genetics predictions, Apple Watch, ad-free. Flo's pregnancy mode is a bolt-on; ProbaBaby is the product. - **Best for Keeping Your Existing Cycle History: Flo** — If you've been using Flo for cycle tracking, staying with it keeps your existing history in place. ProbaBaby tracks cycles too — a free Planning module before pregnancy and an opt-in five-tab Period Tracker after birth, both on one lifelong cycle history — but there's no Flo import, so switching means starting that history fresh. ## Feature comparison | Section | Feature | ProbaBaby | Flo | | --- | --- | --- | --- | | Pregnancy Tracking | Week-by-week timeline | Yes | Yes | | Pregnancy Tracking | Daily content / tips | Yes | Partial | | 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 | Yes | | Health & Symptoms | Mood tracking | Yes | Yes | | Health & Symptoms | Weight tracking + trend | Yes | Partial | | Health & Symptoms | Sleep tracking (pregnancy) | No | Yes | | Birth Prep | Hospital bag (interactive) | Yes | No | | Birth Prep | Birth plan builder + PDF | Yes | No | | Birth Prep | Contraction timer | Yes | No | | Birth Prep | 5-1-1 rule alert | Yes | No | | Birth Prep | Kick counter | Yes | No | | 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 | Partial | | iOS Native Features | Live Activities | Yes | No | | iOS Native Features | Dynamic Island support | Yes | No | | iOS Native Features | Home Screen widgets | Yes | Yes | | 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 | Partial | | Pricing & Localization | Languages supported | 32 | 30+ | | Pricing & Localization | Turkish (Türkçe) | Yes | Yes | ## Methodology We installed Flo 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. Flo is primarily a menstrual cycle tracker with a pregnancy mode bolted on. ProbaBaby is a pregnancy tracker from the ground up. The choice usually comes down to whether you're already a Flo user (continuity matters) or starting fresh and want depth in pregnancy-specific features. Pricing and feature availability are checked at publish time. We update this page when Flo ships a new version. ## Disclosure ProbaBaby is the publisher of this comparison. We do not accept payment, affiliate commissions, or sponsorships from Flo. The App Store link in our card points to ProbaBaby's own listing; the link in Flo's card goes directly to their App Store page with no tracking. ## FAQ **What happened with Flo and the FTC?** In 2021, the FTC finalized a settlement with Flo over allegations that the company shared user health data with third-party analytics providers (including Facebook and Google) despite privacy-policy promises to the contrary. Flo has since updated its data practices, but the incident is the most-cited privacy concern for the app. ProbaBaby was built post-2021 with privacy-first design from day one. **Does Flo have a contraction timer?** No. Flo's pregnancy mode doesn't include a contraction timer or a kick counter. ProbaBaby has both, plus Live Activity integration that keeps the timer visible on Lock Screen and Dynamic Island. **Is Flo free?** Flo has a limited free tier; most pregnancy-mode features are behind a premium subscription. ProbaBaby has all tracking, all 30+ tools, and all content free at any tier — only AI baby predictions are paid (sold as credit packs, with prices set per region by the App Store). **Should I switch from Flo to ProbaBaby mid-pregnancy?** Switching has a small setup cost — copy your due date and known symptoms over manually. The reward is access to the contraction timer, hospital bag tool, kick counter, Apple Watch integration, and an ad-free experience. If you're past week 28, the kick counter and contraction timer alone often justify the switch. **Which has better Turkish localization?** Both support Turkish, but ProbaBaby's pregnancy content is fully Turkish-localized including medical disclaimers, hospital bag items, and contraction-timer alerts. Flo's pregnancy mode is partly localized; most clinical content stays English. ## 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.
