Comparison
Flo 與 Glow 2026：隱私、功能及價格比較
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 都是女性健康應用領域的主要參與者，各自擁有龐大的用戶基礎和社區功能。Flo 是無可爭議的市場領導者，擁有 4.4 億用戶、一個健康聊天機器人和最廣泛的內容庫。Glow 擁有 2500 萬用戶，特別受到嘗試懷孕的女性的歡迎，提供生育追蹤、基礎體溫圖表和活躍的社區論壇。
這兩款應用都強調社交功能——Flo 有其社區故事，Glow 有其論壇。兩者都提供生育追蹤、症狀記錄和預測。對於核心追蹤需求，體驗大致相當。
它們的不同之處在於失敗模式。Flo 故意與廣告商分享數據。Glow 反覆未能通過安全漏洞保護數據。當您的生殖健康數據受到威脅時，故意數據分享和疏忽數據暴露之間的區別幾乎無關緊要。
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 的高級版價格約為每年 49.99 美元。Glow 的價格因計劃而異。兩者都有廣告支持的免費層。經過幾年，這兩款應用的成本對於那些顯然未能保護您的數據的產品來說是相當可觀的。
PinkyBloom 免費。沒有廣告。對於處理生殖健康數據的應用，價格比較應包括數據暴露的成本。Flo 和 Glow 都已證明這個成本是真實的。
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.
