A good fit for people who prefer an upfront App Store purchase with visual analysis and collections. US Mac App Store lists $19.99 upfront; check your region’s current listing.

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.
