Internet video is the future. It's hard to argue that. The mobile landscape is chaotic, though, and figuring out which services have what shows or movies can be a complicated task. Viewdini, from Verizon, wants to be the digital age's TV Guide, aggregating show info, availability, reviews, and discovery into a single app. Search for the name of a show or movie and you'll get info about it, as well as where you can watch it.
In addition to featuring info about shows, movies, and music, the app also integrates reviews. While not explicitly mentioned in the app's description, the video below clearly shows Metacritic's highly-regarded reviews being featured, as well as being "powered by" TV.com, a leading TV database juggernaut.
