Unlike most other messaging apps for your wrist, WearResponses doesn’t try to take over for your main messaging app. Instead, it grafts new capabilities onto the existing SMS reply functionality. Android Wear still doesn’t have customized canned replies for SMS, and that’s what WearResponses provides. You simply add your desired text to the app, and when messages arrive on the watch via WearResponses, they’ll have your custom text as quick reply options. It’s best to turn off Wear notifications for your default SMS app so you don’t get duplicates. The free version limits you to three custom responses, but the $2.99 paid version is unlimited.
