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.
