Phases of the Moon App for iPhone and Android

Phases of the Moon
Want to know the current phase of the Moon at all times? Perhaps you need to do some stargazing or astrophotography, or you really need to debunk some nonsense theories about full Moon madness… then check out our handy mobile app – available on iPhone or Android.

We’ve just done a major update to the app, extending the support to iPhone, and completely rebuilding the Android edition to be smoother and more stable on the wide range of devices.

This latest version of the app is running a full model of the Moon’s orbit and phases, displaying a scientifically accurate simulation of the Moon’s exact phase, size, distance and amount of illumination.

You can swipe the Moon back and forth to see how the Moon’s distance and illumination change over time, or jump to the next full Moon, or see the Moon’s phase at any point in the future. The Android version is especially smooth, and kind of hypnotic as you change the phase.

Here are the features:

  • Beautiful images of the Moon were made by NASA from data collected by the Lunar Reconnaissance Orbiter.
  • Full internal simulation of the Moon’s position and phase. See the current date, phase name, distance and illumination percentage.
  • Swipe left and right to move forward or backwards in time to see what the Moon will look like in the future or past.
  • Click a button to take you to the next full Moon.
  • You can also access a calendar that shows you the phase of the Moon for any date in the future.

You can purchase a copy for $.99 on either Google Play or the iTunes Store, and help support Universe Today.
