Comparison
Flo vs Glow 2026: Privatliv, Funktioner & Priser Sammenlignet
Our verdict
Flo paid $8M in a class action for sharing data with advertisers. Glow exposed 25 million users' data in a 2024 breach after years of documented security failures. Both apps store your data in the cloud; both have failed to protect it. PinkyBloom stores your cycle log on your phone, needs no account, and never sells your data.

Overview
Flo og Glow er begge store aktører inden for kvinders sundhedsapps, hver med store brugerbaser og fællesskabsfunktioner. Flo er den ubestridte markedsleder med 440 millioner brugere, en sundhedschatbot og det mest omfattende indholdsbibliotek. Glow har 25 millioner brugere og er især populær blandt kvinder, der prøver at blive gravide, med fertilitetssporing, BBT-diagrammer og aktive fællesskabsfora.
Begge apps lægger vægt på sociale funktioner — Flo har sine fællesskabshistorier, Glow har sine fora. Begge tilbyder fertilitetssporing, symptomregistrering og forudsigelser. Oplevelsen er generelt sammenlignelig for kerne sporingsbehov.
Hvor de adskiller sig er i deres fejlfunktioner. Flo delte bevidst data med annoncører. Glow fejlede gentagne gange i at beskytte data gennem sikkerhedssårbarheder. Forskellen mellem bevidst datadeling og uagtsom databeskyttelse betyder lidt, når det er dine reproduktive sundhedsdata, der er på spil.
Privacy comparison
Flo and Glow have both failed spectacularly at protecting user privacy, but in different ways.
Flo's sharing was by design, according to the FTC's complaint: it alleged in 2021 that Flo sent menstrual data to Google, Facebook, and Flurry Analytics despite privacy promises. Flo settled with no fine and no admission, and paid $8M to settle a class action in 2025.
Glow's failures were negligent. Consumer Reports flagged "serious security and privacy flaws" in 2016. A California settlement in 2020 covered security failures dating to 2013. Then in February 2024, TechCrunch reported a bug that exposed the personal health data of 25 million Glow users. Three incidents over eight years — a pattern of systemic security failure.
Glow offers an opt-in "Offline Data Protection" mode, but research shows fewer than 5% of users change default settings. By default, data goes to AWS. Flo's "Anonymous Mode" still uploads data to servers.
Both apps' attempts at damage control — Flo's Anonymous Mode, Glow's Offline mode — are opt-in patches on fundamentally vulnerable architectures.
Features and intelligence
Flo is the more complete platform: AI chatbot, 70+ symptoms, community stories, pregnancy mode, and educational content from 120+ medical experts. It's designed to be a comprehensive health ecosystem.
Glow focuses on fertility with BBT charting, ovulation tracking, cycle predictions, and community forums. The forums provide genuine peer support for the TTC community. However, Glow's intelligence layer is statistical, not AI-driven.
Neither app offers voice logging or predictive mood forecasting.
PinkyBloom provides a built-in AI assistant: conversational health assistance, voice logging, mood forecasts, and doctor visit reports. No community forums (which would require cloud accounts), but encrypted partner sharing through PinkyBond provides private one-to-one support instead.
Pricing comparison
Flo koster ~$49.99/år for premium. Glows priser varierer efter plan. Begge har annonceunderstøttede gratis niveauer. Over flere år koster begge apps betydelige beløb for produkter, der har vist sig at fejle i at beskytte dine data.
PinkyBloom er gratis. Ingen annoncer. For apps, der håndterer reproduktive sundhedsdata, bør pris sammenligningen inkludere omkostningerne ved databeskyttelse. Flo og Glow har begge bevist, at omkostningerne er reelle.
There's a better option
Flo intentionally shared your data with advertisers. Glow accidentally exposed 25 million users' data through security failures. PinkyBloom never sells your data, and your cycle log is stored on your phone, not in an account on our servers. Built-in AI, no account, free.
