Everything the moon, nothing you don't need

Widget-first, astronomy-accurate, and private by design. Here is what is inside.

Tonight, at a glance

Open Gibbous for the phase, the illuminated percent, moonrise and moonset for your location, and a countdown to the next full and new moon. It all works offline.

The Gibbous Today screen with the moon, illumination, and moonrise

The lunar calendar

A whole month of phases in one view, each drawn as a small moon. New and full moons are marked; tap any day for its moon, distance, and sign.

A planner for photographers

Moonrise, moonset, and transit height alongside the sun's golden and blue hours, for any place you save, with a read on the best nights to shoot the moon.

The moon through the signs

An optional layer for the astrology-curious: the moon's current sign, what it traditionally means, and when it next changes. Framed as folklore, never forced.

Widgets

Home and Lock Screen widgets in several styles, plus Apple Watch complications and a one-tap Control Center button.

Siri and Shortcuts

Ask Siri for tonight's moon, the moon on any date, or the next full moon. Answers instantly, even offline.

Alerts

A quiet heads-up before every full moon, free. Premium adds new moons, quarters, eclipses, supermoons, and rare moons, plus a digest of the weeks ahead.

Live Activity

Tonight's moon on the Lock Screen and in the Dynamic Island.

Moon journal

A private note under any night's moon, kept on your device. What did you do under the Wolf Moon?

3D moon globe

Tap the moon to spin the whole globe, tilted by tonight's true libration, with the maria and craters where they really are.

Moon compass

A live dial that points at the moon: turn until the marker meets the top, then look up. Works in daylight, and tells you when the moon returns if it is below the horizon.

Meteor showers

The year's major showers with peak nights and rates, and a read on how much moonlight will wash out each one.

Eclipses and supermoons

What is coming in the sky, each explained plainly.

An icon that follows the moon

Optional: the app icon itself updates to the current phase each time you open Gibbous.

In your language

English, Spanish, French, German, Portuguese, and Japanese, on iPhone, iPad, and Apple Watch.

Private by design

No account, no ads, no tracking. Your data stays on your device and your iCloud.

Offline

Everything is computed on your device, so it works with no signal.
