Apple released watchOS 2.0 for the Apple Watch on Monday following an unexpected delay that prevented its rollout along side iOS 9 last week. The update improves overall watch performance, and adds support for native third-party apps.

watchOS 2.0 also adds support for remotely wiping your Apple Watch if it's lost or stolen, improves Siri's capabilities, and adds new watch faces along with third-party watch face complications.
Apple didn't release watchOS 2.0 on Wednesday like it originally planned thanks to a bug the company felt was significant enough to warrant a delay. The company didn't say what the problem was, but it most likely stemmed from a FairPlay copy protection issue developer James Thomson discovered that could prevent native Apple Watch apps from running.
watchOS 2.0 is free, and is compatible with all Apple Watch models. To install the update, launch the Apple Watch app on your iPhone, then go to General > Software Update.
