| Native macOS UI | Yes | Yes |
| Cleanup workflow | Stage items in the Collector, then send the reviewed batch to Trash. | Moves only selected items to macOS Trash after confirmation. |
| Reports and portability | The developer documents exporting maps as posters with Command-Shift-E. Keep that image as a reference; it is not a scan file that NullDisk can import. | The official page does not establish scan export. Keep useful paths before rescanning; permission scope can make totals differ. |
Delve: what stands out
A good fit for Apple Silicon users on macOS 26+ who want two maps and staged cleanup.
Delve: strengths
- Treemap, sunburst, and file list
- Logical and on-disk measurement with filtering
- Quick Look, collector-to-Trash, and map image export
Considerations
- Requires macOS 26 or later
- Apple Silicon only in the current requirements
- A map export is a visual record, not a file backup
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 Delve?
A good fit for Apple Silicon users on macOS 26+ who want two maps and staged cleanup. Vendor lists $4.99 once after a 14-day trial.
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.
