Simple, effective and actually practical. Very fast scan times (unlike 99% of storage analyzer with the claim of being modern).. Still works very well even on newer android because it's simple by design and very well made. If being able go delete files inside an app is a feature, than I just go and delete files myself!! At least I can do that, can't I?

BEST STORAGE ANALYZER. It's free, open-source, fast, and simple. I've been using it since 2010! Use it to find what's eating up your storage AND if you are rooted, it can help you locate all the hidden pieces of your apps (scan \data) faster than most explorer apps! At this writing, it hasn't been updated since 2017, but it doesn't need to be. It's basically perfect.

Simple, great, tiny app! Been using for years and years. Does exactly what it says. Shows you exactly what is using space graphically without and fluff. App size less than 1mb, so you can install it even when your phone is super full to see what is taking space. No ads! No annoying notifications! No background processes that slow down your phone! I've had one or two devices where the manufacturer configured the file system weird, so you have to click on the right storage device, but that is the fault of the device manufacturers, and really simple bug.
