Apple watchOS 2: What You Need to Know About the Software Update

Expect faster performance and more native apps for your wrist.

Apple rolled out the software update today after its scheduled Sept. 16 release was delayed due to a bug that a company representative said was "taking a bit longer to fix than we expected."

Perhaps the biggest appeal of watchOS 2 is the ability for apps to run natively, meaning many can run entirely on the Apple Watch, allowing for a faster experience with even more functionalities.

Among the new capabilities available in watchOS 2 are photo faces, including time lapses of city scenes, the ability to see a different photo every time a user glances at their wrist and nightstand mode, turning a charging watch into an alarm clock.

A time travel feature will also let users turn their crown to leap forward and backward in time to see their schedules. Siri will also respond to a voice command to start counting a workout, without a user having to touch their Apple Watch.
