Have you ever had the itch to watch Twitch on Nintendo Switch? Available now as a free download on the Nintendo eShop, the Twitch app lets users watch both live and VOD content on the go in handheld mode, or on the big screen when the Switch is docked.

Since Twitch is best known for gaming livestreams, it makes sense that a lot of people who play Nintendo Switch are probably also Twitch viewers. You can’t stream your games through the Twitch app (streaming set-ups are complex and bandwidth-intensive!), but it’s easy to browse and search for streams. You can sign into your Twitch account to easily keep up with your favorite streamers, but you can’t use the chat function in the app. It would be difficult to keep up with a Twitch chat while trying to type with your joycons, so it’s not a huge loss. Plus, you can scan a QR code on your phone to join the chat. At that point, if you’re not docked to a TV screen, you might as well just use the iOS app, though.
