Can't you just say "Hey siri, add a note"? I add reminders, send texts, etc. that way.

Yeah, there's lots of places you can't speak out loud bc it's disruptive to others though. Personally I set a lot of Siri reminders, but it's weird and uncomfortable to talk loudly at your phone in public spaces so I can only use it at home or outdoors. If the ring can follow through on the promise of being able to whisper to it, that's fairly valuable imo
