Features

Uninstall Applications

• Scans /Applications and ~/Applications for installed apps
• Finds all related files: caches, preferences, logs, containers, saved state, cookies, crash reports, and more
• Shows app icon, name, bundle ID, and total size
• Select/deselect individual components before removing
• Moves files to Trash (safe, reversible deletion)

Clean Up Leftovers

• Detects orphaned files from previously uninstalled applications
• Scans Library directories for bundle IDs that don't match any installed app
• Smart filtering: distinguishes between standalone app leftovers and helper components
• Multi-selection support (Cmd+click, Shift+click) for batch cleanup
• Human-readable descriptions for known applications

Clean Drive

• System-wide cleanup across 8 categories:
  • Log files — system logs, app logs, analytics data
  • Cache files — user and system caches, container caches, temp files
  • Trash — items in the Trash
  • Browser data — Chrome, Firefox, Brave, Opera, Safari caches
  • Mail cache — Apple Mail caches
  • Xcode junk — DerivedData, Archives, Device Support, Simulator caches
  • iOS device backups — old iPhone/iPad backups
  • Installers — DMG, PKG, and ISO files in Downloads
• Visual color bar showing category proportions
• Confirmation dialog before cleanup
