Being able to quickly reply to a message from your Apple Watch is a big part of its appeal. Currently, you have the option of sending a voice-note, a dictated message (transcribed by Siri) pr using one of the pre-defined replies provided by Apple. The list of replies houses six different responses, albeit generic ones. With a few seconds of your time, you can overwrite Apple's default replies with your own. Here's how:
- Launch the Apple Watch app on your iPhone.
- Scroll down and tap on Messages from the list of apps.
- At the bottom of the screen is an option titled Default Replies -- tap on it.
- Replace any responses you have no need for, with a custom reply of your choosing.
The next time you reply to, or compose a new message your custom messages will available as an option.
