Nektony Disk Space Analyzer Pro: what stands out
A good fit for people who prefer an upfront App Store purchase with visual analysis and collections.
Nektony Disk Space Analyzer Pro: strengths
- Sunburst, largest-items list, and Quick Look
- Collect items for moving or removing
- Scans external storage and accessible cloud folders
Considerations
- Paid edition distinct from the free-download listing
- Access depends on macOS permissions and chosen scan locations
- A cloud-folder scan is not proof of direct provider-account access
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.

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.
