On-device Siri, thanks to the new S9 SiP hastens commands that don’t rely on the internet. So starting a workout, setting an alarm and a ton of other features become a lot easier to initiate just with voice. Even dictation is a lot more accurate and faster, something that I regularly use while driving and replying to texts.
It’s in the watchOS where most of the newness resides, including more comprehensive cycling metrics along with enhanced support for Bluetooth accessories. Most apps are totally redesigned, including the communications app for calling from the watch directly. You also avail of perks like playing back a group FaceTime audio call, FaceTime video message on your watch, contact sharing and more.
