So glad to see this thread. I have been using Wunderlist, but you have to launch the app, find the list, press the screen and say what you want to add. A bit cumbersome. I had tried Siri reminders and could never get it to add groceries. I though it was an Apple Watch issue. However, I unpaired my watch with the phone and tried it again and it fixed the issue. I then shared the list so either of us could have the list available at the store.
I also added the Nano app so I could see the list on the watch. Very convenient way to add new stuff we need to pick up.
