With the Flo app, you can accurately track your menstrual cycle and predict your next period. In addition, the app encourages you to gain an understanding of your own body.

White feather against a pink background The Flo app is a comprehensive solution for women who want to monitor their menstrual cycle. With the Clue app, you can easily record your menstrual cycle, identify your most fertile days, predict your next period and track your pregnancy. The app also provides information on health and sexuality. It is based on an algorithm. This means that the more regular and detailed the user tracks, the more precise the predictions become. The app encourages you to gain an understanding of your own body and recognise patterns in your menstrual cycle, without serving as a primary contraceptive method.
