It doesn't do anything yet though.
In a somewhat shocking turn of events, the Nintendo Switch Online app is now available to download on both Android and iOS (no Windows Phone though, sorry). We expected the app to be available on Friday with the launch of Splatoon 2, but it’s good to know that you can download it and log in right now instead. The one downside is that servers aren’t currently live, so after logging in all you’ll see is a server maintenance message. But hey, it’s something, right?
You can follow the links below to download the app:
Android: Play Store
iOS: App Store
Sonic and speed, they just go together
Not ideal.
Finally, some preorder bonuses.
