|---|---|---|
| Best fit | People who want saved storage history or a companion on iPhone/iPad. | Users wanting one account-based analyzer across Mac, Windows, and Linux. |

| Pricing and editions | Commercial app; check current developer and App Store purchase options. | Vendor currently offers lifetime Pro free with a Bravely Account; sign-in is required. |
| Open source | No | No |
| Native macOS UI | Yes | Cross-platform interface |
| Cleanup workflow | Preview, reveal, or move selected items to the bin. | Confirmed collector action: Trash/Recycle Bin or permanent deletion. Duplicates use Trash/Recycle Bin. |
| 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 vendor describes recent locations, not an interoperable report format. Preserve paths and collector selections separately before rescanning. |
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
Diskaroo: what stands out
A good fit for users wanting one account-based analyzer across Mac, Windows, and Linux.
Diskaroo: strengths
- Treemap, sunburst, filters, and largest-items list
- Collector with Trash/Recycle Bin or explicit permanent removal
- Content-based duplicates; Quick Look on Mac
Considerations
- Requires an account before the first scan
- Current free offer depends on claiming Pro in the app
- Linux build requirements include GTK 4
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 Diskaroo?
A good fit for users wanting one account-based analyzer across Mac, Windows, and Linux. Vendor currently offers lifetime Pro free with a Bravely Account; sign-in is required.
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.
