Comparison
Flo vs Glow 2026: Privacidad, Características y Precio 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 y Glow son ambos actores importantes en el espacio de aplicaciones de salud femenina, cada una con grandes bases de usuarios y características comunitarias. Flo es el líder indiscutible del mercado con 440 millones de usuarios, un chatbot de salud y la biblioteca de contenido más extensa. Glow tiene 25 millones de usuarios y es particularmente popular entre mujeres que intentan concebir, con seguimiento de fertilidad, gráficos de BBT y foros comunitarios activos.
Ambas aplicaciones enfatizan características sociales: Flo tiene sus historias comunitarias, Glow tiene sus foros. Ambas ofrecen seguimiento de fertilidad, registro de síntomas y predicciones. La experiencia es ampliamente comparable para las necesidades de seguimiento básicas.
Donde divergen es en sus modos de fallo. Flo compartió intencionalmente datos con anunciantes. Glow falló repetidamente en proteger datos a través de vulnerabilidades de seguridad. La distinción entre compartir datos intencionalmente y la exposición negligente de datos importa poco cuando está en juego tu salud reproductiva.
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 cuesta ~$49.99/año por premium. Los precios de Glow varían según el plan. Ambas tienen niveles gratuitos con soporte publicitario. A lo largo de varios años, ambas aplicaciones cuestan sumas significativas por productos que han demostrado fallar en proteger tus datos.
PinkyBloom es gratis. Sin anuncios. Para aplicaciones que manejan datos de salud reproductiva, la comparación de precios debería incluir el costo de la exposición de datos. Flo y Glow han demostrado que ese costo es 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.
