Use your current location or save a place to check visibility, altitude, azimuth, moonrise, moonset, and the Moon’s path across the sky. Browse the detailed monthly calendar or check the essentials from widgets and Apple Watch.
Explore the Moon up close on iPhone and iPad: pinch to zoom from 1× to 4×, then move the enlarged view with one finger. Touch and hold the Moon and move your finger to examine details with the magnifier. Resize the active standalone Moon with ⌘+ and ⌘−; ⌘0 restores its default size.
Siri and Shortcuts bring the Moon into your day: get phase and illumination for a chosen date, find the next moonrise, moonset, full moon or new moon, and check current altitude and direction relative to the geometric horizon.

Selene strips away the typical astronomy-app clutter. What remains is a focused, beautiful interface that makes checking the moon feel like a moment of peace.
Selene includes Home Screen widgets in multiple sizes and Lock Screen widgets — circular, rectangular, and inline — so you can see the current moon phase without opening the app.
Selene collects zero data. There is no analytics, no account system, and no cloud sync. All lunar calculations run entirely on your device.
Location access is used solely for local observation calculations and never leaves the device.
