The second watchOS 5 beta includes a few notable additions to the Apple Watch operating system, the most important being a functioning Walkie Talkie app.
Aside from the now working Walkie Talkie app, a new "Now Playing" widget appears at the top of the active watch face whenever music is currently playing on a connected device. Tapping it takes you directly to the Now Playing screen.
Similarly, a Walkie Talkie icon resides in the same place whenever it is enabled. Both the Now Playing and Walkie Talkie icons fit in the same place that the Workout icon does when in the middle of a session.
Beyond those two major additions, not much has changed with this developer beta.
Related to Apple Watch, the latest iOS 12 update references several as-yet-unannounced Apple Watch models, which could debut as early as this September.
