A new feature of watchOS 2 finally allows users to send messages completely hands free, and even though there is a catch, it's a much welcome improvement to communicate via text message without having to physically touch the device.
The catch is that this new feature only applies to messages you create from the Home or Watchface screen using Siri. It does not work for replies to messages you receive, and doesn't work if you go straight to the Messages app and tap Reply. Still, if used right, it can make the process of sending messages completely frictionless.
