A disk space app for Mac that never deletes anything
SpaceCoach scans your disk, shows what's taking up the space, and explains each big item in plain English: what it is, and whether it's safe to remove.
macOS 15 Sequoia or later · Apple silicon and Intel
How it works
One scan sorts your disk into eight plain categories, then lists the biggest things worth a look, largest first.
Click into a ring to go deeper, or switch to a treemap. Every folder shows its real size on disk, and Reveal in Finder takes you straight to it.
Finder, System Settings and a scan rarely agree. Where did it go? lays the numbers side by side and explains the gap: purgeable space, Time Machine snapshots on your Mac, and folders macOS keeps private.
Big items get a What is this? card: what the thing is, why it's there, and Apple's own way to deal with it. Each card carries one of four plain labels:
The promise
“Cleaner” apps make money by scaring you into deleting things. SpaceCoach explains instead, and leaves every decision to you.
SpaceCoach has no code that deletes, moves or changes your files. The only things it writes are its own settings and scan history.
Scans run on your Mac and stay there. No analytics, no accounts. The app goes online only to check for updates, when you ask it to or turn on automatic checks.
When something can be cleaned up, SpaceCoach shows the safe way to do it yourself: the right System Settings pane, the app that owns it, or Finder.

Questions
No. It shows and explains what's on your disk, and it can't delete anything. When something can be cleaned up, it tells you the safe way to do it yourself.
Because a big file isn't the same as a useless one. An old iPhone backup might be the only copy of your photos. SpaceCoach tells you what something is and how safe it is to remove, then leaves the choice with you.
It's the catch-all part of the storage bar in System Settings. It often includes caches, Time Machine snapshots kept on your Mac, and space macOS will free on its own when it needs to. Where did it go? breaks it down for your Mac.
macOS keeps some folders private, like Mail, Messages and your Photos library. With Full Disk Access SpaceCoach can measure them too. It's optional: without it the app still works and lists those folders as not scanned.
No. Scans happen on your Mac and stay there, and there are no analytics. The only time SpaceCoach goes online is to check for updates: when you choose Check for Updates, or automatically if you turn that on.
No. You pay $9.99 once during the launch period ($14.99 after that) and get every 1.x update.
Yes. One Pro license covers all the Macs you personally own or use.
Ask for a refund within 30 days of buying and you'll get your money back, no questions asked.
