Well… it’s helped me spontaneously skip 30 seconds ahead in my podcasts when I’m least expecting to.
I wish it could just be used to control notifications instead. If a notification comes in, just use double tap to dismiss and move on to the next notification (if there is one). If a notification came in a little while ago and I raise my wrist and it’s just showing the watch face, I’d like to double tap to pull down the notification shade to see the last notification.
Really though, I think it would be more convenient if Apple implemented wrist gestures, like Android Wear used to have. Double twist the wrist one way and it brings up the widgets, the other way brings up notifications - double twisting again in the same direction will scroll through whichever you’re looking at. Then the double tap feature could just be used for selection of a notification, wrist gestures could be used again to scroll through the notification and then to cycle between a few options like “dismiss”, “reply with voice”, “reply with text”, with double tap again functioning as select. Multiple notifications could be read, replied to or dismissed without having to use your other hand (or nose).
I’ll say it again, Apple could make this device so much easier to use one-handed if they just borrowed a little bit from the old Android Wear gestures that always worked so well for me (even on their comparatively junk hardware)… Flick the watch away/towards you with wrist twists to scroll up/down and highlight things, we could now use double-tap to select, and something like lift and lower forearm quickly to go back.
As it is currently though, assistive touch just isn’t great to use. You could always buy and try and return if it doesn’t work out.
