What's a good Android app for clearing out all the junk files that slow down my phone after I've been messing with a bunch of APKs?

Okay, so Quick Clean - Space Cleaner, from a technical standpoint, is pretty decent at what it does. I'm always sideloading APKs and testing stuff, which leaves a ton of residual files. This app actually finds them. The interface is clean, and the scan engine seems pretty thorough. I like that it separates the junk into categories – cache, obsolete APKs, empty folders, etc. Makes it easier to see what you're deleting. It loads in about 2 seconds on my Pixel 7, and after running it, I usually free up a gig or two of space. The dev team really thought about making it user-friendly, which is a plus. It's not perfect, but it's way better than some of the other bloated cleaner apps out there. Plus, it barely uses 60MB of RAM while running, which is a win in my book. No more spaghetti code situations here, hopefully!
