Why does the moon phase look flipped?

The lit side is mirrored between hemispheres. In Settings, turn on the Southern Hemisphere view to flip the moon to match your sky.

Moonrise and moonset are blank.

Rise and set times need a location. Allow location access, or add a place in Settings, and they will appear.

How accurate are the times?

Phase and illumination are computed from established algorithms and validated against published ephemerides. Moonrise and moonset are accurate to about a minute for your location.

Do alerts work offline?

Yes. Alerts are scheduled on your device from the moon's own cycle, so they do not need a signal or a server.

How do I restore a purchase?

In Settings, tap Restore purchases. Your Premium or Lifetime will return on any device signed in to the same Apple Account.

Is my data private?

Yes. There is no account, and Gibbous collects no personal data. See the Privacy Policy for the details.
