About this app

Your period knows what you did last week.
Marea is a menstrual health app for teens and young women, with privacy at its core. It goes beyond tracking your period. It helps you understand the connection between your daily habits, sleep, stress, movement, and how your cycle actually behaves, so you're never just guessing.

WHY MAREA IS DIFFERENT
Most period trackers just record what happened. Marea helps you understand why. Log a few daily habits alongside your cycle, and Marea's on device insights show you real patterns, like how your sleep the week before your period tends to affect your cramps, or how your stress levels line up with your mood.
Everything is stated honestly. No causal claims, no "eat this in this phase" advice. Just what your own data shows, explained in plain language.

WHAT YOU GET
Track your cycle in under 60 seconds a day. Log your period, symptoms, and five simple daily habits with a few taps.
See your patterns. As you log more cycles, Marea unlocks deeper insights, from basic summaries to trend detection to gentle, personalized nudges before your period arrives.
Learn as you go. A library of short, science backed, non judgmental content on periods, hormones, and your body, written to be genuinely relatable, not clinical or preachy.
Know when to see a doctor. Marea never diagnoses, but it flags patterns worth mentioning to a healthcare provider, like unusually long cycles or pain that isn't responding to normal care.

PRIVACY, BUILT IN FROM DAY ONE
Marea doesn't ask for your name, email, or phone number to get started. Your data lives on your device, not on our servers. We don't see it and we don't sell it.

BUILT FOR YOU
Marea meets you where you are, whether this is your first period tracker or you've used one before. Start logging today and let the insights build from there.
Download Marea and start understanding your cycle, not just tracking it.
