LOS ANGELES -- Disney is launching a digital movies app that allows fans to store movie purchases online and play them back over Apple devices and computers.

The launch of Disney Movies Anywhere coincides with the release of hit film "Frozen" on digital platforms. Users who link the app account to Apple's iTunes digital store will receive a free copy of "The Incredibles."

The app is built on The Walt Disney Co.'s KeyChest technology, which stores and records consumers' purchases of digital movies on distant servers. The app also recognizes codes that have enabled digital downloads of Disney movies since 2008.

KeyChest is similar to UltraViolet, a digital locker system
