Mine are always labeled "Misc"
You need "Magic Home Inventory"

I don't know if there is a version of it for iPhones (I have Android).
It is basically a "containers of containers of containers" inventory app. Your HOUSE is a container. It contains ROOMS. Rooms may contain a CLOSET. A closet usually contains SHELVES. Shelves contain a mixture of BOXES and individual items. Boxes contain individual items - like scissors, binoculars, camera, etc. You can organize your containers as you wish. Name them what you want. Include pictures of them sitting in their location so you can identify them. Pictures of the insides to show their contents. Lists of contents. And the stuff is searchable.
I have a room in the house (OK, actually several of them!) that have several of those plastic totes with all kinds of stuff inside. The totes are different models and are stacked on each other. So I name an individual tote something like LrgBlkYel which means the large black tote with the yellow lid. Sometimes I may have three of these things stacked on each other. So I'll take a picture of the stack in the room and add a red arrow pointing to the one I'm inventorying. Then I list it's contents and take a picture of the inside. And the names end up being LrgBlkYel#1, etc. You could make a stick-on label that has this written on it and slap it on the box for even faster identification.
OK. For home use, I found this not as useful as I'd hoped, because things are often pulled out of their "container" and moved elsewhere never to be returned to their container. Oops. I'm just not strict enough on that the have the inventory be all that helpful for tracking items that I use a lot. And I don't need an inventory app for things that I use a lot. Well, scratch that. Yes, I do lose items all the time. But I'm not about to inventory every place I haphazardly set something down.
However, for our storage locker, where things pretty much stay in their boxes and don't get moved around much, this app is great. When you open the locker and see this massive sea of stacked boxes, it does help to do a search for the item you're looking for in the app - and end up with a picture of the locker/boxes with a red arrow pointing to the box your desired thing is in.
The app is not 100% intuitive and there is a learning curve. And you'll spend quite a while entering your inventory (photos are optional, but helpful for some things). I ended up with a hybrid of things inventoried. For example, you could have a box containing scissors, stapler, pens, pencils, etc. and put it into the program as containing one item - "office supplies". If needed, you can take a picture of the contents to show what those office supplies are if you prefer that over an individual item list. Or just skip the individual item list entirely and settle for "office supplies" being good enough.
Warning: To use an app like this, you kind of have to be a nerd, geek, obsessed, and driven. The faint of heart will probably give up around box #3. Kind of like people deciding they want to read the Bible, and trying it in canonical order: Genesis - cool! Exodus - this is awesome! Leviticus - Uhm, are there any Gilligan's Island reruns on TV I could maybe watch instead?
Things that you will need to investigate are exporting the data - you don't want it to be only on your phone that you just dropped in the lake. Personally, I would prefer an app that runs as a central server on a computer, and your phones and tablets act as clients that communicate with the server app. Everything is stored on the server. This app I am talking about here is not that. So in my mind, it is limited. But it may be good for some people, doing some things, which is why I mention it. I use this app, but only on occasion. I do not use it as much as I thought I would. Mostly, it's for storage locker stuff. And even then, most boxes are listed as containing only a few things that are classes of stuff rather than individual stuff. Like "hiking gear", "cook books", "sprinkler parts", things like that. It's much less intimidating to inventory stuff into classes/categories. That's good enough to find what you're looking for. You always end up with a few of those "Misc" boxes. That's where pictures of contents come in handy.
