Fewer duplicates. Keep what matters. DupCleaner finds duplicate files in folders you select and exact duplicate photos and videos in your photo library, so you can compare copies and decide what stays. ONE PASS FOR FILES AND PHOTOS Your existing lifetime pass includes duplicate photo cleanup at no extra charge. Your One-Year Pass and cleanup credits also work across files and photos. There is no separate photo pass. EXACT DUPLICATES IN YOUR PHOTO LIBRARY Compare original photo and video resources, Live Photo video and editing data. Similar-looking images are not treated as identical, and bursts are excluded. Keep at least one photo in every group and protect favorites. Select copies for deletion and review them alongside the photos you keep. With limited access, only the photos you allow are compared. iCloud originals not on your device are skipped by default; you can choose to download them for comparison. CHECK FILE COPIES TO KEEP Preview photos and PDFs found in your selected folders. Compare names, locations, sizes and modification dates, then check the file copies you want to keep. Open supported files in another app or copy a name and location to find the original in Files. FOCUS ON WHAT YOU NEED Search file names and paths, filter by type, switch between duplicate groups and folders, and collapse long groups. Cleanup review includes only groups in the current search or filter. Choose exclusions and a default keep rule. A separate option to clean every file copy warns again when nothing will remain. COMPARE ON YOUR DEVICE File and photo contents are compared locally, not uploaded to a DupCleaner analysis server. Unreadable originals are not assumed to be duplicates. Cloud originals may need to download and take longer to compare. REVIEW BEFORE CLEANUP Move to Trash is the default for files. Unsupported locations and failed moves never switch to permanent deletion automatically. Photo deletion uses Apple's photo-library confirmation. If you use iCloud Photos, deletion also applies to connected devices; recovery is available in Recently Deleted in Photos. Album placements of deleted copies are not transferred to the photos you keep. Displayed sizes describe original resources, not a measurement of newly available device storage. FREE SCANNING. CLEAR PURCHASE OPTIONS. Scanning, results and previews are free. A Single Cleanup credit is used only when a selected cleanup succeeds. Pro includes one-tap scanning of saved folders and unlimited cleanups. The One-Year Pass lasts one year from purchase and does not renew automatically. Pro Lifetime is a one-time purchase. Existing purchase entitlements are preserved. Compare and clean up in layouts that fit iPhone and iPad. File Trash support and recovery depend on the storage location. Back up important files and photos before cleanup.

Verdict

The call

The clearest difference is ads: Similars at none against DupCleaner's shown. Similars also leads on review sentiment (75% vs 50%) and rating (4.7 vs 4.5). DupCleaner's advantage is monetization model (free vs free with in-app purchases) and update cadence (every 5 days vs every 10 days). On price, ratings volume, in-app purchases and device support there is nothing between them.
