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
Space Lens (CleanMyMac): what stands out
A good fit for existing CleanMyMac users who want visual disk exploration within their suite.
Space Lens (CleanMyMac): strengths
- Bubble visualization of local and external storage
- Folder-by-folder browsing and a reviewed removal list
- Part of the broader CleanMyMac maintenance suite
Considerations
- A suite module rather than a standalone purchase
- Check module availability in your CleanMyMac edition
- Suite licensing may be more than needed for disk analysis alone
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 Space Lens (CleanMyMac)?
A good fit for existing CleanMyMac users who want visual disk exploration within their suite. Part of CleanMyMac; check current subscription/one-time plans and edition availability.
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.
