ESPN has today updated its ESPN and WatchESPN iOS apps, giving them both access to iOS 10's Single sign-on feature among other things. Both of the newly updated apps can be downloaded from the App Store right now.
With the official launch of Single Sign-on via both tvOS 10.1 and iOS 10.2 at an unspecified point in the presumably near future, Apple has built a new App Store section which includes a selection of apps that support the new feature.
