| Best fit | People who want saved storage history or a companion on iPhone/iPad. | Mac users seeking an analyzer plus duplicate and photo cleanup tools. |
| Visualization | Radial pie chart, treemap, and snapshot sequences | Sorted folder breakdown and cleanup lists |
| Platforms and requirements | macOS, iOS, iPadOS | macOS 10.13+ (vendor requirements) |
| Pricing and editions | Commercial app; check current developer and App Store purchase options. | Free App Store download; full functionality via subscription or lifetime purchase. The subscription includes a seven-day trial. |
| Open source | No | No |
| Native macOS UI | Yes | Yes |
| Cleanup workflow | Preview, reveal, or move selected items to the bin. | Review each module’s action; ordinary cleanup and permanent shredding have different recovery implications. |
| Reports and portability | Export a snapshot and keep it: the developer documents JSON/TSV records that can be viewed in a text editor. NullDisk does not import these snapshots. | The cited product page does not document scan export. Keep duplicate decisions and paths separately; hard-link accounting in NullDisk is not duplicate-content detection. |
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
Disk Xray: what stands out
A good fit for Mac users seeking an analyzer plus duplicate and photo cleanup tools.
Disk Xray: strengths
- Size-sorted folder scanner
- Byte-by-byte duplicate checks and similar-picture search
- App uninstaller, disk cleaner, and optional file shredder
Considerations
- Six modules serve different cleanup tasks
- Shredder operations are permanent
- Vendor limits content overwriting to supported HDDs, excluding SSD/APFS/network drives
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 Disk Xray?
A good fit for Mac users seeking an analyzer plus duplicate and photo cleanup tools. Free App Store download; full functionality via subscription or lifetime purchase. The subscription includes a seven-day trial.
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.
