These are my tips for shopping lists.
I use the heck out of the shopping mode action in that post. It’s so nice to wander around the grocery store checking things off and not having to wake up the phone for every item. I do my shopping lists in “Simple List” syntax and have the font size set for that syntax to around 24 points, too, so the checkboxes are dead easy to tap.
That said, I don’t do a lot of capturing items for the list. I tend to sit down and plan meals for the week and make a list in one sitting - not constantly add to it all week.
