🔍 What is Flo?

Flo is an AI-powered women's health tracking platform that helps users monitor menstrual cycles, ovulation, pregnancy, and overall reproductive health. Developed by Flo Health Inc., the app uses sophisticated AI algorithms to provide highly accurate period and ovulation predictions while offering personalized health insights. With over 300 million downloads worldwide, Flo is one of the most popular and trusted women's health applications globally, used by women across every stage of life from menstruation through menopause.

The platform's AI prediction engine analyzes years of user data including cycle length, symptoms, basal body temperature, and lifestyle factors to deliver remarkably accurate forecasts. Flo's predictions improve over time as the AI learns individual patterns, achieving cycle prediction accuracy that rivals clinical methods. Beyond tracking, Flo provides a comprehensive health companion experience including symptom logging, medication reminders, and personalized articles addressing hundreds of women's health topics written by medical professionals.

Flo has made significant investments in medical accuracy and privacy. The app's content is reviewed by an advisory board of leading OB/GYNs and health researchers. In response to privacy concerns around reproductive health data, Flo introduced Anonymous Mode, allowing users to access all features without associating personal data with their identity. The platform also offers Flo for Partners and a specialized pregnancy mode with fetal development tracking, contraction timers, and tailored health guidance throughout each trimester.
