Google Hangouts has become much more useful on the Apple Watch, thanks to an update to its iOS app. Yesterday, among its usual bug fixes, Google added the ability to reply directly from notifications in Hangouts, and thanks to Apple's quick reply implementation, that functionality now also works on the Apple Watch. While Hangouts has been available for the Apple Watch for some time, you could only read and dismiss messages. Now you can choose from a selection of predetermined responses, or dictate a Hangout message right from your wrist. If you haven't received the update yet, head over to the App Store through the link below.
