The Marea mark, a soft blob in rose and lilac

A kinder way to know your cycle

One short, gentle note a day. Not a chart to decode.

Coming soon to the App Store

A note, not a dashboard

Marea gives you one warm, phase aware note each day, written for where you actually are in your cycle. No graphs to interpret, no numbers to worry about.

Log how you feel in a tap

Pick up to four feelings from a rotating set. Add a private note if you want one. It takes a few seconds and it stays yours.

Built for real cycles

Marea learns your rhythm from what you log instead of holding you to a number you guessed once. If you are on hormonal birth control, pregnant, postpartum, irregular, or in perimenopause, it adapts instead of pretending.

Your data stays yours

Everything lives on your iPhone and syncs through your own private iCloud. There is no account, no server of ours, and no way for us to read any of it.

Marea is not a fertility or contraception tool, and it is not a medical app. It does not diagnose, treat, or prevent any condition. Please talk to a clinician about anything health related.
