Comparison
Flo vs Glow 2026: Privacidade, Funcionalidades e Preço Comparados
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 e Glow são ambos grandes players no espaço de aplicativos de saúde feminina, cada um com grandes bases de usuários e funcionalidades comunitárias. Flo é o líder de mercado indiscutível com 440 milhões de usuários, um chatbot de saúde e a biblioteca de conteúdo mais extensa. Glow tem 25 milhões de usuários e é particularmente popular entre mulheres que tentam conceber, com rastreamento de fertilidade, gráficos de BBT e fóruns comunitários ativos.
Ambos os aplicativos enfatizam funcionalidades sociais — Flo tem suas histórias comunitárias, Glow tem seus fóruns. Ambos oferecem rastreamento de fertilidade, registro de sintomas e previsões. A experiência é amplamente comparável para necessidades básicas de rastreamento.
Onde eles divergem é em seus modos de falha. Flo compartilhou intencionalmente dados com anunciantes. Glow falhou repetidamente em proteger dados através de vulnerabilidades de segurança. A distinção entre compartilhamento intencional de dados e exposição negligente de dados importa pouco quando estão em jogo os seus dados de saúde reprodutiva.
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 custa ~$49.99/ano para premium. O preço da Glow varia conforme o plano. Ambos têm níveis gratuitos suportados por anúncios. Ao longo de vários anos, ambos os aplicativos custam somas significativas por produtos que falharam demonstravelmente em proteger seus dados.
PinkyBloom é gratuito. Sem anúncios. Para aplicativos que lidam com dados de saúde reprodutiva, a comparação de preços deve incluir o custo da exposição de dados. Flo e Glow provaram que esse custo é real.
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.
