Here at Flo, we strive to help you understand your cycle and body better. We do this by working with over 100 health and medical experts.

With Flo’s free subscription, you can enjoy best-in-class period and ovulation tracking and candid conversations in our safe community space, Secret Chats.

Flo’s free version offers:

Period and ovulation predictions
After you add your period dates to the app, Flo will start making predictions for your next period, ovulation, and fertile days. All predictions are marked with different colors in the app so they’re easy to understand. To improve Flo’s predictions, we suggest you add your periods from the last 12 months or at least the last three cycles.

80+ symptoms to track
Flo is more than a period tracker. It can also be a place to track your health and well-being. That’s why Flo offers 80+ symptoms and events to log. Tracking your symptoms can give you an overview of how you’re feeling and help you notice any changes throughout your cycle.

Custom reminders
Flo can remind you when your period is about to start or when you’re likely to ovulate so you can feel prepared. It can also help you if you take birth control or medication or are seeking to build a new habit like drinking more water.

Secret Chats is a safe and friendly space in Flo where you can connect with millions of other members like you, share stories, support each other, and talk about all things female health — anonymously. Join the conversation now.
