Map your storage. Clear what’s safe.
DiskApp surveys every folder, shows what each one holds and how old it is, and flags what can go. Nothing moves until you choose, and everything goes to the Trash first.
DiskApp isn’t from the App Store yet, so the first open needs one extra approval in System Settings. See how (20 seconds)
A real scan: 258 GB across 3.1M files, read in 13.9 seconds.
- 1
Scan
Point it at your Home folder or the whole disk. Every folder sized by what it actually holds — hard links counted once, symlinks never followed.
- 2
Review
A sunburst and a map show exactly where the space went. Caches, idle build folders and deleted apps' leftovers are flagged because a rule or an app's bundle ID proved it, never on a hunch.
- 3
Clear
Tick what you want gone and confirm. It moves to the Trash, exactly like dragging it yourself — Put Back works until you empty it.
Inside the app
A real scan of a demo home folder. Yours will look like this in a few seconds.
One scan, the whole picture
How full the disk is, what's safe to clear and the biggest folders, next to a sunburst you can click into ring by ring.
More about Overview
Built to answer one question fast
Where did my space go, and what can I get back without breaking anything.
A sunburst you can actually read
Click a ring to zoom in, click the center to go back. Every folder is sized by what it really holds on disk — hard links counted once, symlinks never followed.
A map for the rest
A canvas treemap for when you want to scan a whole drive at a glance — built to stay smooth past a few million files, not just a demo folder.
Findings, not guesses
Caches, idle build folders (node_modules, target, .venv…) only count when a real project file proves it's a project. Nothing is flagged on a hunch.
Trash, never rm
Every clear re-checks against fresh findings right before it runs — a stale screen can't delete something that's no longer safe. Everything goes to the Trash; Put Back works.
Apps, and what they leave behind
Each app's real size, counting the data it keeps in your Library. Uninstall sends the app and that data to the Trash together. Apps you already deleted show up too, with their leftovers matched by bundle ID, not by name.
Every cache, not just the famous ones
Beyond the tools DiskApp knows by name, every folder in your Library's Caches is listed with its size. Ones nothing has touched in a month are pre-selected; the rest wait for you to tick them.
Nothing moves that isn’t provably safe
The rule engine refuses first and explains why, not the other way around. It’s the same code path whether you’re clicking a checkbox or nothing at all.
- System folders, Keychains, iCloud Drive, Messages, Photos, and .ssh are refused outright — not just hidden, structurally untouchable.
- Tool-managed data (Docker, pnpm store, Xcode simulators…) is never selected for you. You get the exact command with a Copy button, or tick it yourself, down to a single simulator.
- A build folder only counts as “idle” if its project hasn't been touched in 7+ days, and active projects are always left alone.
- Every clear is appended to a plain JSON-lines log at ~/Library/Logs/DiskApp/operations.log — nothing happens silently.

First open takes one extra step
DiskApp isn’t notarized by Apple yet (see below), so the first time you open it macOS says it “could not verify DiskApp is free of malware.” This is that one workaround, needed once:
- 1Open DiskApp.dmg and drag DiskApp into Applications
- 2Open DiskApp. macOS can't verify it yet, so click Done (not Move to Bin)
- 3System Settings → Privacy & Security → scroll down → Open Anyway
- 4Click Open Anyway again, then confirm with Touch ID or your password
- 5DiskApp opens. You only do this once
- Or skip steps 2 to 4: run this in Terminal before the first open.
