I'm looking for a disposable camera app, not sure what to search for

I want a camera app that makes it easy to quickly delete unimportant photos. I'm talking about pictures of receipts, ingredient lists, parking stall numbers, other memo type photographs that I won't need for longer than a few days.

Ideally, all it will do is store photos taken with the app in a folder where I can do a big "delete all" whenever I feel like freeing up space on my phone. I don't want any features beyond that.

It seems like it should exist already, but I'm having a hard time figuring out what search terms to use. Has anyone got something like it? I'm on an iPhone so iOs preferred.
