Although the possibility to download videos is the most noteworthy feature, YouTube Go offers a lot of other cool features as well. For example, you can preview any video before streaming or downloading it, seeing only a few still images of the video's content and minimizing data usage. Plus you have the option to watch videos in basic quality.
Another interesting feature YouTube Go offers is how it lets you send and receive videos you've downloaded via Bluetooth. Thanks to this new feature, you won't use a single kilobyte when sharing your favorite videos with friends.
YouTube Go is an alternative YouTube client that's especially useful for anyone with slow or unstable Internet connections. While it doesn't offer all the features the official YouTube app does, it does have some really useful and unique ones instead.
Requires Android 4.1 or higher.
