Does the moon affect your mood? Millions believe it does. Science says probably not. Mooni lets you find out for yourself.
Check in daily with how you're feeling — mood, energy, and sleep — and Mooni automatically tags each entry with real-time lunar data. Over time, see your personal patterns emerge and compare them against centuries of lunar beliefs.
It takes 30 seconds a day. The insights last a lifetime.

What's new (v1.0.2)
Bug fixes:
• App icon badge no longer gets stuck on "1" after a notification — and any leftover badge clears as soon as you open the app.
• Sleep-quality emojis on the check-in flow now register taps anywhere on the emoji, not just the inked pixels.
• Moonrise, moonset, and the next full/new moon are now shown in your local time. Users east or west of UTC were seeing times off by hours and dates off by a day.
• Moon-event notifications fire on the correct local day (was a day early for users east of UTC).
• Patterns chart no longer drifts behind a day if you leave the app open across midnight.
Testers: please verify the moon details sheet shows correct local times for your timezone, and that opening the app clears any badge.
