Built around the truth
A moon app where the numbers matter.
Every screen starts with on-device astronomy, then gives it the native Apple treatment: Metal rendering, useful widgets, local notifications, Live Activities, Siri, Shortcuts, and complications.
Live Moon
Correctly lit and oriented
The disc is rendered on your device, lit from the computed Sun vector and rotated for your sky, including libration and the bright limb.
Plan ahead
Calendar and almanac
Daily phase glyphs, named full moons, rise and set, apogee and perigee, and computed lunar eclipses in local time.
At a glance
Widgets and Watch
Home Screen, Lock Screen, StandBy, Apple Watch complications, and a moonrise Live Activity.
Photography
Golden and blue hour
Sunrise, sunset, civil twilight, and photography windows calculated locally, with optional Apple Weather cloud cover.
Private
No account. No tracking.
Aphelion never receives your location or preferences. Optional city naming and cloud cover communicate directly with Apple; Lunar has no analytics SDK, advertising network, or developer-operated server.
Verified
Published methodology
The astronomy engine is continuously checked against JPL Horizons, USNO, NASA GSFC, and NOAA references. Read the validation method.
