Comparison
Flo与Glow 2026：隐私、功能与价格比较
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和Glow都是女性健康应用领域的重要参与者，各自拥有庞大的用户基础和社区功能。Flo是无可争议的市场领导者，拥有4.4亿用户、健康聊天机器人和最丰富的内容库。Glow拥有2500万用户，特别受到尝试怀孕女性的欢迎，提供生育追踪、基础体温图表和活跃的社区论坛。
这两个应用都强调社交功能——Flo有社区故事，Glow有论坛。两者都提供生育追踪、症状记录和预测。对于核心追踪需求，体验大致相当。
它们的不同之处在于失败模式。Flo故意与广告商共享数据。Glow则因安全漏洞多次未能保护数据。当涉及到您的生育健康数据时，故意共享数据与疏忽暴露数据之间的区别几乎没有意义。
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的高级版费用约为49.99美元/年。Glow的定价因计划而异。两者都有广告支持的免费层。经过数年，这两个应用的费用对于那些明显未能保护您数据的产品来说是相当可观的。
PinkyBloom免费。无广告。对于处理生育健康数据的应用，价格比较应包括数据暴露的成本。Flo和Glow都已证明这一成本是真实存在的。
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.
