Flo vs Glow 2026: Privadesa, Funcions i Preu Comparats
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 i Glow són ambdues grans jugadores en l'espai de les aplicacions de salut femenina, cadascuna amb grans bases d'usuaris i funcions comunitàries. Flo és el líder indiscutible del mercat amb 440 milions d'usuaris, un xatbot de salut i la biblioteca de contingut més extensa. Glow té 25 milions d'usuaris i és particularment popular entre les dones que intenten concebre, amb seguiment de fertilitat, gràfics de BBT i fòrums comunitaris actius.
Ambdues aplicacions fan èmfasi en les funcions socials — Flo té les seves històries comunitàries, Glow té els seus fòrums. Ambdues ofereixen seguiment de fertilitat, registre de símptomes i prediccions. L'experiència és àmpliament comparable per a les necessitats de seguiment fonamentals.
On divergeixen és en els seus modes de fallada. Flo va compartir intencionadament dades amb anunciants. Glow va fallar repetidament a l'hora de protegir les dades a través de vulnerabilitats de seguretat. La distinció entre compartir dades intencionadament i l'exposició negligent de dades importa poc quan es tracta de les teves dades de salut 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 costa ~$49.99/any per a la versió premium. Els preus de Glow varien segons el pla. Ambdues tenen nivells gratuïts amb suport publicitari. Al llarg de diversos anys, ambdues aplicacions costen quantitats significatives per a productes que han fallat de manera demostrable a l'hora de protegir les teves dades.
PinkyBloom és gratuït. Sense anuncis. Per a aplicacions que gestionen dades de salut reproductiva, la comparació de preus hauria d'incloure el cost de l'exposició de dades. Flo i Glow han demostrat que el cost és 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.
