Wal-Mart-owned video-on-demand service Vudu has updated its iOS apps to allow movie downloads for offline viewing. The Android phone version of the app has had this feature for awhile, but Android tablets are still unable to download and view their Vudu/Ultraviolet collection on their tablets.
Other additions to the update include a reworked player to make the app easier to use, as well as support for closed captions on the iPhone. It's worth noting that the Flixter iOS app already allowed for Ultraviolet downloads. Ultraviolet is a digital rights authentication service that allows DVD and Blu-ray buyers to redeem unique download codes for digital viewing later.
You can find the updated app for free in the iTunes store now.
