I assume this is for a third party To-Do app? Because otherwise, most people can just use Siri to create a new Note or Reminder. For me, this is nearly always by way of my AirPods if they're in, or my Watch. I absolutely do not understand the point of a $100 ring to do this.
Incredibly stupid. I can't believe anyone thought this was a good idea. I'm sure he wasn't the only one, which is sad. Just to throw it away when the battery dies, what a joke.
