How it works

Made for the hard weeks

01

Log your day in seconds

Tap your mood, mind, body and energy, then what you did: walked, rested, saw friends, talked it through. Add a diary note if you want to.

02

See your PMDD window coming

Your calendar shows every phase, your period, and when your PMDD window is predicted, so the hard days don't catch you off guard.

03

Notice your patterns

Insights lay out your symptoms, energy and activities across your cycle, so you can see when things show up and what you were doing.

04

Let your partner in, softly

Connect a partner and choose exactly what they see. Changes show up in their app right away.

We're here

No. Luna is a tracking tool, not a substitute for a doctor. It can't diagnose PMDD, but your logs are useful to share with one.

Only what you switch on: a heads-up before your PMDD window, your phase and predictions, your daily energy score, and the symptoms you log. Never your diary notes.

You can still log everything. Hormonal birth control changes typical cycle patterns, so phase info may not match your body as closely.

Try it free for 7 days. After that it's $2.99 a month or $19.99 a year.
