| Cleanup workflow | Preview, reveal, or move selected items to the bin. | Moves only selected items to macOS Trash after confirmation. |
| Reports and portability | Export a snapshot and keep it: the developer documents JSON/TSV records that can be viewed in a text editor.

Disk Graph: what stands out
A good fit for people who want saved storage history or a companion on iPhone/iPad.
Disk Graph: strengths
- Switch between radial charts and treemaps
- Logical size, allocated size, or file-count modes
- Export snapshots and animate changes across a sequence
Considerations
- Mobile scans cover locations accessible through Files
- Snapshots record inventory, not backed-up file contents
- Historical snapshots need a fresh scan before cleanup
SimplyDiskSweeper: what stands out
A good fit for Mac users who want a focused list workflow and explicit confirmation.
SimplyDiskSweeper: strengths
- Largest accessible items shown first
- Folder hierarchy browsing and filtering
- Selected items move to Trash after confirmation
Considerations
- Paid upfront rather than a free edition
- Measures accessible items within the selected folder
- Ranked browsing rather than a whole-drive graphical map
For a useful comparison on your own drive, match the scan root, access permissions, and size mode. Chart style changes how you explore the results; it does not by itself establish measurement accuracy.
Common questions
When should I choose Disk Graph?
A good fit for people who want saved storage history or a companion on iPhone/iPad. Commercial app; check current developer and App Store purchase options.
When should I choose SimplyDiskSweeper?
A good fit for Mac users who want a focused list workflow and explicit confirmation. US Mac App Store lists $14.99 upfront; one-time purchase.
Will both apps show the same size?
Not necessarily. Match the scan root, permissions, exclusions, and logical/allocated-size mode. Hard links, APFS clones, snapshots, sparse files, and cloud placeholders can change totals. A reported size is not a guaranteed amount recovered after deletion.
