Thanks very much, rjbull, for your helpful follow-up about rShoppingList. It has a number of attractive features, but right now I feel it offers too many features that I don't need, such as comparing prices at different stores, or telling me how much I paid for an item the last time I bought it. Heck, I don't even want to have to put in the prices, not even with a bar scanner.  Having an entire page devoted to each item seems like overkill to me, at least in terms of what I want from my shopping list.  I'm looking for something quite simple, though perhaps with a few more features than mouser's Checklist DC currently has. I think I'm going to see whether I can make Checklist work for me. If it can't, I may give rShoppingList a try.

Thanks very much, rjbull and IainB, for your suggestions. rShopping List - Grocery List looks interesting, but two of the four stores I'd probably include don't have easily identifiable aisles (at least, I've never found them easily identifiable or findable  :o ). And the ones that do, like Safeway, would require me to go to the store and make careful notes about what is found in each aisle. That may be more work than I want to do.

As for PriceCruncher, its main feature seems to be calculating prices in varying sizes. That's a useful feature for many people, but it's not really what I'm looking for.

I also don't need to be able to list all the stores that have the items I'm looking for. I have a good sense of when I want to go to the Safeway, when to Trader Joe's, etc. I don't need an app that will tell me in which store(s) I can find apples or butter or chicken breasts.  I pretty much know that already.  What I need is a list that I can use when I go to store X or Y to remind me of what items I want to buy. I'd like that list to be organized so that all the vegetables I want will be listed together, as will all the fruit, all the poultry, all the dairy products, etc. Actually, it's somewhat more complicated than this, since the Safeway I shop in is at times rather chaotic, but I can see how I might deal with that. I suspect that thanks to NigelH's suggestion, Mouser's Checklist DC may wind up being the app that will best meet my needs.  :up:

Thanks very much, NigelH and Mouser, for your replies. I think NigelH may have provided a good solution to the problem I was having. I was trying to have a three-level arrangement.  The top level--the Category--would be the store (e.g., Safeway). The next level, which I suppose would have to be the Label--would be the kind of item I wanted, for example Produce. And under Produce would be individual items such as grapes, tomatoes, butternut squash, etc.  What I think NigelH has proposed combines levels two and three into a single level, the Label, which would combine a level-two designation AND a level three: produce-tomatoes, produce-butternut squash, etc. Actually, I think I like Nigel's replacing Produce with the more specific terms like "fruit" and "veggies".  And if I list my items in alphabetical order, at least I'd still have all the veggies listed together, all the fruits listed together, etc., even though the veggies wouldn't be listed near the fruits. 

Mouser, I don't think screen size was an issue here. I was able to see everything (indeed, my phone, an LG Stylo 4, is toward the larger end of the phone spectrum). My problem was partly terminology, but mostly I was trying to have a three-level arrangement, not realizing that Checklist was designed for just two levels. But NigelH's suggestion to have the Label combine two levels into one should give me what I need. My one concern is that, especially since the Label font is larger than the Category font, there may not be enough room to include, say, "veggies-butternut squash".  I wonder whether you could make possible a choice of font sizes?  Or, if not, at least make the Label font smaller than it currently is?

Again, many thanks to both of you!  :Thmbsup:
