## Kitsmith's take

The free tier already does real work: find and remove duplicate files and folders across any disk, external drive, or Photos/Music library, with byte-for-byte SHA comparison for accuracy. The Pro in-app purchase adds the features power users actually ask for — removing duplicate folders (not just files), merging similar folders together, and Auto Select rules for bulk selection. Notably Apple-notarized and, per Nektony’s own site, a 10M+-download, 4.6-star track record — not a fly-by-night utility.

## Features

- **Byte-for-byte comparison:** A dedicated Compare Files/Folders mode confirms whether two items are true duplicates rather than just similarly named.
- **Similar-photo and -music detection:** Finds near-duplicates, not just exact copies — a series of near-identical burst shots, or the same song ripped twice.
- **Safe removal with history:** Duplicates go to the Trash by default (recoverable), with a removal history you can review afterward.
