Juli Clover writes for MacRumors about the upcoming release of Nintendo’s previously announced iOS app, which will serve as a companion to the Nintendo Switch:
During a Nintendo Direct event this morning, Nintendo announced plans to release a new "Nintendo Switch Online" app on July 21, the release date for Splatoon 2. According to Nintendo, the Nintendo Switch Online app, available for iOS and Android, is designed to "enhance your online experience for compatible games on the Nintendo Switch console."
At launch, the only game compatible with the Nintendo Switch Online app will be Splatoon 2. The app will let users voice chat with friends, invite people to online matches, create teams, and access SplatNet 2. SplatNet2 offers up online play statistics and info on upcoming game features.
At launch all components of the new app will be free for all users, but it’s unclear how long that will last. Nintendo has stated that from some point in 2018 and beyond, its online service for the Nintendo Switch will cost $19.99 per year or $3.99 per month, and there has been no clarification to this point on which aspects of the companion app might be tied to that paid service.
