## About

Flo helps you understand your cycle, from your period and ovulation to pregnancy and perimenopause 🌸 Log your period dates and symptoms, and it predicts your next period and your fertile days. Pregnancy mode follows development week by week, and a perimenopause section covers the symptom changes of that stage. The cycle tracker with period and ovulation predictions is free, while Flo Premium adds a health assistant chatbot, personalised health reports, detailed pregnancy tracking and Flo for Partners. If you'd like extra privacy, Anonymous Mode lets you use the app without a name or email linked to your health data. Made by Flo Health, on iOS and Android.
