At one point they moved it into some web app that I could only access from my phone by spelunking through the Home app. Has that changed?
When it worked, it was great.
I didn't like that change, but it does work just as well now, and keeps all the same features (checking it off, manually adding stuff, sharing with friends/family members, etc...).
I do wish they kept it in keep, and even allowed more "lists". Being able to tell it to add a book to my "reading list" would have been fantastic...
It's a shame they force you to use it, over just adding to a shopping list in Google Keep.
I was considering getting the Home Mini but now I'm not so sure (grocery list, weather check, and general help (timer/conversions) while cooking would have been my main usage)
