Vudu is a platform owned by Fandango Media that delivers both free and paid content. Initially, the service focused exclusively on a digital media player known as the Vudu Box.
At the moment, instead of paying a monthly fee, the mechanism involves renting movies and TV shows for 24 hours or outright buying content that can be watched at any time, on pretty much all devices.
The Vudu Android app is quite intuitive as well. For example, you can easily scan a picture of the bar code on the movie box.
If it happens to be available digitally (and most of them are), don’t hesitate to pay the small fee and the content will show up in your Vudu library.
