Again we started with the beta versions of Apple this week and in this case we are facing the first beta version of watchOS 3.2 where it is added SiriKit that allows developers to use the wizard for their applications and theater mode. This update was leaked last week on the network when they released the macOS, iOS and other betas, but it was not until today when Apple released it for developers.
The theater mode in the Apple watch is nothing other than what we had to use in the iPhone to "not disturb" other people when we are using the device. What it does in the case of the Apple watch is to stop activating the screen when we lift the wrist (if we have it activated) but the notifications will continue to arrive thanks to the vibration. The user will be able to see these notifications by pressing on the screen or by pressing the Digital Crown, but this will not be activated automatically.
Introduced in watchOS 3.1.3, Theater Mode allows users to quickly silence the Apple Watch and avoid waking up the screen by raising the wrist. Users will continue to receive notifications (including haptics) while in Theater Mode, which they can view by tapping the screen or pressing the Digital Crown
The new version watchOS 1 beta 3.2 is now in the hands of developers and now it is expected that they will refine the details to launch the final version as soon as possible.
