This update from Apple will improve the functionality of this app. No new features are included. • Updated for iOS 7 and iOS 8. iOS 7 or later is required for this update. • Supports full resolution on iPhone 6 and iPhone 6 Plus. • The Sky Compass projection is now based on angular elevation. This better indicates how high the Moon and Sun are in the sky.

Improved spin rate, especially for iPhone 5.

- Support for iPhone 5 and iOS 6. - The minimum required iOS version is now iOS 4.3.

Graphics performance improvements.

- Updated for full resolution on the new iPad. - Improved lighting map generated from the Lunar Reconnaissance Orbiter Wide Angle Camera Digital Terrain Model (LRO WAC DTM).

- Optimized for iPad 2. - Sharper labels. - Better rendering around the poles. - Updated surface normal (lighting) map using the very latest Lunar Orbiter Laser Altimeter (LOLA) data from NASA's Lunar Reconnaissance Orbiter. Version 2.1: - Moon Globe HD is now a universal app supporting iPhone (3GS and later) and iPod Touch (3rd generation and later) as well as iPad. Because Moon Globe HD relies on advanced OpenGL ES 2.0 graphics, it does not support original iPhone, iPhone 3G, or 1st or 2nd generation iPod Touch. Regular Moon Globe still supports those older devices. - There is now a separate button in the toolbar to turn on or off the Sky Compass (as with regular Moon Globe on iPhone/iPod Touch), and the compass is now larger and displayed in the center of the screen when turned on. Compass direction can be turned on or off in the Options menu (for devices that have a magnetic compass). - Support for iOS 4.
