Operating System[edit source]

Third-party applications[edit source]
Third-party applications are supported through the WatchKit API. However, in order to save battery and allow a less powerful processor, applications are "run" on the phone and streamed to the Watch over Bluetooth. iOS 8.2 (and up) comes with a dedicated "Watch" app to perform the initial pairing and download third-party "Watch apps".

- American Airlines (B06)
