Don't call it a YouTube replacement—users can't upload their own videos, for starters. And while there is a search box, that's not what drives the app. It's more of a channel-surfing engine—you just swipe around and check stuff out. The videos autoplay, and you can swipe up to change channels or swipe forward to get a new video.
The navigation feels much more natural by result. Tapping on YouTube videos seems so choosy by comparison: you're picking one thing. I want to watch…this. Swiping feels like you're just flipping through channels with a TV remote: next, next, next. Instead of choosing one thing, you're just asking the app to show you "something else," and then you can decide if you like it and want to finish watching it.
