My Luna

A calm way to follow your cycle — mapped to the phases of the moon.

Beta

Join the iOS beta on TestFlight
Android — coming soon

Not on the App Store or Google Play yet. iOS testing runs through Apple's TestFlight app; Android opens later.

It stays on your phone

The privacy policy spells out exactly what each switch sends, and what we can see.

What it does

The cycle ring

One dot per day of your cycle, so where you are today is a glance rather than a calculation.

Log what matters

Flow, symptoms, mood, notes — and your own custom fields for anything Luna didn't think of.

Forecasts from your own history

Your next period is estimated from the cycles you have actually logged, not a fixed 28 days.

Phases, explained

Each phase gets a moon, a colour and a plain-language guide to what is typical during it.

Gentle reminders

A nudge before a period is due, or to log the day. Scheduled on your phone, never on a server.

Share with a supporter

Invite a partner or friend into a read-only view of exactly what you pick — and disconnect any time.

My Luna is not a medical device and not a contraceptive. It describes patterns in what you log; it does not diagnose anything, and it is not a substitute for advice from a clinician.
