Snippet: watchOS 2 Released ☇
Alex Guyot for MacStories did an in-depth review:
watchOS 2 brings no dramatic visual change from its short-lived predecessor. The platform remains young, and has a long way to go before it reaches any significant modicum of “maturity”. Questionable choices such as the honeycomb Home screen layout, assignment of the hardware side button to the Friends interface, and lack of support for third-party watch faces all remain. But under the hood, in the areas of connectivity, performance, power, and system and hardware level access, watchOS 2 makes major leaps forward.
If you haven’t already, go grab it from the Watch app on your iPhone (General > Software Update). If you run into any weirdness during installation, I recommend restarting one or both devices.
