Frequently asked questions
Flo uses artificial intelligence to make more reliable predictions about your cycle, meaning you’re always prepared for your period or predicted fertile window. In fact, 90% of people using Flo say the app accurately predicts the start of their period. You can start using Flo without any information about your previous cycles, but it’ll start making accurate predictions more quickly if you log the dates of at least three previous periods.
*Flo should not be used as birth control.
Flo has both free and paid versions, with all the basic features available even if you don’t pay. If you’re using the free version, you’ll have the option to move to the Premium version at any time. With Flo Premium, you’ll get access to even more useful features, like custom cycle reports and weekly health insights.
You can now share insights about your cycle with your partner using Flo for Partners. About 60% of women believe that their partner’s lack of knowledge about female health affects their relationship. We’re actively trying to change that with Flo. Whether your goal is to track your cycle, get pregnant, or follow your baby’s development, your partner will get health insights and tips to proactively support and understand you.
To access Anonymous Mode, go to “Settings” and tap your profile picture. You’ll see the Anonymous Mode button just below. In this mode, you’ll still benefit from accurate predictions and personalized insights, but without any connection to your personal information.
