Unlike some big streaming video services, Vudu isn’t sitting on the fence when it comes to offline playback. The Walmart-owned provider has revamped its Android and iOS apps with several big features, most notably an option to download your rentals — you can watch that movie in mid-flight even when the in-air WiFi is lousy. You’ll also have access to movie extras for supporting titles, and iOS users now get both higher-quality 1080p HDX streaming as well as AirPlay. And if you’re still attached to hard copies, you can buy discs inside the app instead of heading to the web. So long as you live in the US and like Vudu’s `a la carte approach to movies and TV, you can check out the upgrade right now.
