  The moon, right now

  Open the app and see tonight's moon drawn at its true position in a sky dome, right now. Azimuth, altitude, geocentric distance, apparent size and illumination, all at once. Not another moon-phase calendar — an instrument for where the moon actually is.

  Find

  A full-screen compass points you to the moon: "34 degrees right, 12 degrees up." Hold up your phone and walk your gaze straight to it.

• 45°

  Size

  Compare tonight's moon against this year's largest and smallest full moons, drawn at true relative scale. See its geocentric distance in kilometres, its apparent diameter in arcminutes, and where it ranks among every moon this year.

  Rise, set and arc

  Moonrise, transit and moonset shown with exact times and compass bearings. A height curve from dusk to dawn shows how far the moon has climbed and when it will set.

  Widgets

  Three home screen sizes and two lock screen widgets show altitude, bearing, phase, and tonight's rise and set times. Each widget can watch a different place.

  Real imagery, verified accuracy

  Real lunar surface imagery from NASA's Lunar Reconnaissance Orbiter, with libration and parallactic angle applied so the moon is turned the way you actually see it — including the flipped orientation seen from the southern hemisphere. Checked against JPL Horizons: bearing within 0.0034 degrees, altitude within 0.0014 degrees, apparent size within 0.0029 arcminutes, libration within 0.037 degrees.
