Features.

How the features fit together

Spotless starts with one scan of your disk. Every page reads from that scan, so the space map, Storage by type, duplicates and the cleaning list never disagree about how big something is. You scan once, then look at the result from whichever angle answers your question.

Looking

The space map, Storage by type and System Data show where space went. Nothing on these pages deletes anything.

Choosing

Review before every clean turns your choices into a list of paths and sizes. Export plan writes that list to a text file so you can read it away from the app. Locked areas keep Photos, iCloud and active projects out of the list unless you say otherwise.

Cleaning up after yourself

The app uninstaller, duplicates, developer storage and startup items handle the cases where a plain junk scan finds nothing. The memory page and menu bar monitor watch the Mac while you work.

What every feature has in common

Each one reads the same disk scan, shows sizes in the same units as Finder, and routes deletion through the same review step. Each one links to a page that explains what it does and what it will not touch, so you know the limits before you buy.
