Flo Ovulation & Period Tracker

Flo is a comprehensive period and ovulation tracker designed to help you understand your menstrual cycle and overall health. With over 570 million downloads, it provides science-backed insights for regular or irregular periods, ovulation prediction, and fertile window tracking. You can log over 70 symptoms and moods to receive personalized cycle summaries that you can share with your doctor.

For those trying to conceive, Flo offers educational features like basal body temperature tracking and ovulation predictions based on your logged data. During pregnancy, the app switches to provide week-by-week guidance, visual updates on your baby's development, and expert-reviewed content. It also supports perimenopause with tools like a Perimenopause Score and Menopause Timeline to track symptom changes.

Flo prioritizes your privacy with dual ISO certifications and an Anonymous Mode that lets you use the app without linking personal identifiers. The free version includes core cycle tracking tools, while Flo Premium adds daily tailored insights, in-depth pregnancy features, a Symptom Checker, fertility insights, and a 24/7 virtual Health Assistant. Flo is not a birth control method and does not provide medical advice; always consult a healthcare professional.
