Generally speaking, this app runs fine, and I use it for numerous, varied shopping lists, not just groceries. The reason I use it more than other grocery lists is the Apple Watch app, which runs OK for a third party app. One more star (4 stars) if the watch app were streamlined and less steps, and another star (5 stars) for getting rid of adds that now appear.
