YouTube Go was one of the first apps with the “Go” moniker that Google later adopted on Android and its other online services. Aimed at developing markets where connectivity may be more constrained, it features a number of optimizations.
In the case of YouTube Go, Google built a brand new client from the ground up. Key features include strict control over data usage and other local optimizations:
On YouTube Go, we’ll show you a video preview when you tap on a thumbnail, giving you a better sense of what the video is about before you decide if you want to watch it. You can then choose to download the video for viewing later or stream it now. And we also allow you to choose the amount of data you’d like to spend on that video.
Those offline downloads — compared to YouTube Red — are free and can also be shared locally using peer-to-peer connections.
Since launch, YouTube Go has also gained the ability to download, stream, and share high resolution videos, in addition to basic and standard quality.
Meanwhile, Google has unsurprisingly confirmed (via The Verge) that there are no plans for a launch “in countries with more developed networks,” including the United States, Canada, Japan, South Korea, Germany, France, or England.
