Like the title says. Android users with a 645 can reply to messages with quick, canned responses. iOS users cannot, for reasons that escape me. Any hope this functionality is in the works for iOS users?
Probably not. Apple's scheme (I believe) relies on companion apps on the smartwatch to communicate with the main app on the phone (Messages in this case). Since Apple isn't going to create a Messages app for Garmin or anyone else, there will be no responding to texts. Pebble was able to workout a deal with the major carriers in the US where you could send a response directly through the carrier. It fit the bill of responding to text messages, but since it bypassed Apples Messages app, those responses were not recorded anywhere, so you ended up with a one-sided conversation in your message log.
