Android Wear Gets Monochrome Mode in ‘Biggest Ever Update’

What has been billed as ‘the biggest Android Wear update ever’ has added Wi-Fi support, hands-free controls and always-on apps. Devices using the OS can now connect to phones over Wi-Fi, which dramatically increases the range of the link. Always-on apps keep applications open on-screen at all times, rather than closing them when the screen goes dark. Apps enter a monochrome mode to save battery, instead.
