Find what takes space.Choose what to clear.

Uninstall apps and their leftovers

Review an app and the support files linked to it. Shared data stays in place, and protected Apple apps cannot be removed.

Find what's old, not just what's big

Age Map groups files by modification date. Review older files and add the matching set to Cleanup.

Duplicates, by content

Byte-for-byte matching finds real duplicates across every folder you scan, not just files that happen to share a name.

Quick Wins from your scan

Downloads, caches and logs, iOS Simulators, node_modules, build artifacts and Xcode DerivedData are totalled the moment a scan lands.

Snapshots you can compare

Keep the result of a past scan and hold it against today's to see exactly which folders grew while you weren't looking.

Review before cleanup

Add files to Cleanup and review them before moving anything to Trash.
