Flowly is a smart, beautifully designed period tracker that helps you understand your body on a deeper level. From predicting your next period to tracking pregnancy week by week — everything you need is right here, and it's completely free.
Flowly isn't just a period tracker. It's a full reproductive health companion that grows smarter with every cycle you log.
Flowly supports both light and dark themes so it always feels right — whether you're checking in at noon or 2am.
















































Most apps just count days. Flowly learns your body's actual rhythm and gets smarter every single cycle.


Flowly uses an adaptive prediction algorithm that factors in your cycle history, logged symptoms, and phase patterns to give you accurate forecasts — not just averages.
A quick daily check-in takes less than a minute and builds a picture of your health that no doctor's appointment can match.
Every day you open Flowly, you can log how you're feeling across every dimension of your health. Over time, these logs reveal patterns you'd never notice on your own.


When you're expecting, Flowly switches into a full pregnancy companion — week by week, milestone by milestone.


Flowly's pregnancy mode gives you detailed week-by-week updates on your baby's development, plus all the tools you need to stay on top of your own health throughout the journey.
A supportive community and a rewarding streak system make building healthy habits feel natural — not like a chore.
Flowly's community is a safe, moderated space where women share experiences, ask questions, and support each other. And the more you engage with your health, the more you're rewarded for it.


Here's the full picture of what Flowly actually does — every feature, every tool, every tracker. All free.
No complicated setup. No subscription. Just download, tell Flowly about your last period, and it takes care of the rest.
Clean layouts, intuitive navigation, and a design that respects your time and attention.
