Since its launch in August 2011, Rivolu‘s Moon Calendar app hasn’t been provided much more than maintenance, that is, until today. Primarily relevant to iPad owners, v1.1.5 contains a revised user interface for the iOS tablet, including an azimuth and elevation pane.

To enhance the iPad experience, the biggest change is a significant increase of color placement through the UI. Offering both beautification and section highlighting, the calendar body now has a dark blue tint, the day of the week header has a blue gradient, and the moonrise, moonset, sunrise, and sunset headers are appropriately colored in either yellow or blue.

In addition to more color, Rivolu made a few layout changes. Not only has the decorative image been moved from the top of the sidebar to the bottom, it’s now a far less distracting picture. Likely debatable in usefulness, the other modification was reducing the moon phase photo size to allow the display of the currently selected location.

And finally, the previously iPhone and iPod touch-only azimuth and elevation details pane is now available on the iPad. Accessed with a simple swipe left anywhere on the calendar, this section consists of both numerical and visual reports of the moon’s angle and elevation relevant to the horizon. By default, the data is shown for the current time, but can be adjusted in 10 minute intervals.

Moon Calendar is a universal app compatible with iPad, iPhone, and iPod touch running iOS 3.2 or later, and available in the App Store for $0.99.
