Description by Helene Choo Written by the developer, not by AppBrain. Click to read.
You feel a shift before your period: your mood drops, your anxiety spikes, and you might say things you regret. And then it passes... until next month.

You've probably been told it's "just PMS". That maybe you're too sensitive.

You deserve better. You deserve to actually understand what's happening in your body, and to know that there is nothing wrong with you.

Moon Quest is a menstrual cycle app, mood tracker, and period tracker alternative built specifically for people with PMDD, PME, and PMS.
Not a typical period tracker, but a mood forecast powered by your cycle.

WHAT'S REALLY GOING ON

Short daily journeys connect your biology to your lived experience. In plain language, without clinical jargon.
Cycle science doesn't have to be complicated.

Whether you have a PMDD diagnosis, suspect PME (premenstrual exacerbation of anxiety, depression, ADHD, and more), experience severe PMS, or have no label at all, Moon Quest meets you where you are.

YOUR EMOTIONS ARE VALID

Moon Quest's mood tracking and cycle tracking features let you log how you feel each day.

Every mood you log sharpens your personalised emotional forecast, helping you:

• Predict mood changes before your period
• Understand hormonal patterns
• Reduce anxiety linked to your menstrual cycle

Because what you feel has a biological explanation and follows a pattern.
Once you see that pattern, you start to take back control.

CYCLE KNOWLEDGE IS POWER

The Learn library is a free menstrual health resource covering:

• PMDD, PME, PMS
• Premenstrual symptoms
• Menstrual cycle phases
• Hormone and mood changes

Moon Quest gives you the language, the context, and the self-knowledge to ask for the support you need, and to walk into any appointment knowing what to ask for.

We're one of the very few period and mood tracker apps that addresses PME, the cyclical worsening of pre-existing mood conditions during the luteal phase.

SUPPORT WHEN YOU NEED IT

Because PMDD and PME can be serious, support is always easily accessible:

• Global helpline directory
• Breathing exercises
• Grounding tools

YOU'RE IN CONTROL

No streaks. No guilt. No pressure to show up perfectly every cycle.
Moon Points reward curiosity, never compliance.

Moon Quest is not a medical or diagnostic tool. It's a companion for those navigating premenstrual mood disorders, hormone changes, and cycle-related mental health.

You're not broken. You're cyclical.
