Most cleaning apps on the App Store focus on the photo library. Zero Duplicates focuses on your files: the downloads, documents, PDFs, videos and audio files that pile up in the Files app and quietly fill your storage. Zero Duplicates compares files by their content, not by their names. A renamed download, an attachment saved twice, a document copied into three folders: all of them are found, even when the file names look nothing alike. MADE FOR THE FILES ON YOUR DEVICE • Scan any folder you choose: On My iPhone, iCloud Drive, external drives • Downloads from Safari, Mail and Messages • Documents: PDF, Word, Excel, Pages, Numbers, Keynote • Images, videos, audio recordings, archives and more • USB drives and SD cards (with adapter) CONTENT MATCHING File names lie. Zero Duplicates reads the actual content of every file, so duplicates are found even when they were renamed, moved or saved from different apps. AUTO-SELECT IN SECONDS Automatic selection keeps the newest or the oldest file in every duplicate group. Review, tap once, done. No scrolling through hundreds of files by hand. SEE BEFORE YOU DELETE Every duplicate can be previewed before deletion, and you choose which copy stays. At least one version of every file always remains, so losing all copies is impossible. Deletion is permanent, so nothing is removed without a clear confirmation first. PRIVATE BY DESIGN Scanning happens entirely on your device. Your files are never uploaded anywhere. HOW IT WORKS Pick a folder, scan, review what was found, delete with confidence. Three steps to a cleaner device. System files are protected automatically. Perfect for: • Anyone seeing "Storage Almost Full" warnings • People who download and share lots of files • Managing documents, media and work files on the go • Cleaning up iCloud Drive across devices TRY WITHOUT RISK Free to download • Unlimited scans • 500 MB free deletion Premium unlocks unlimited deletion and advanced features.

Verdict
The clearest difference is rating: Zero Duplicates at 4.8 against LudyActions's 4.2. Zero Duplicates also leads on ratings volume (65 vs 5). LudyActions's advantage is in-app purchases (none vs 3) and review sentiment (100% vs 80%). On price, update cadence, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Zero Duplicates sells 3 in-app purchases, starting at $4.99 per month. LudyActions asks for nothing beyond the download.
Zero Duplicates holds the better App Store score, 4.8 against 4.2. That said, the two scores are not equally well evidenced: Zero Duplicates has 65 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 80% of Zero Duplicates's written reviews are positive against 100% of LudyActions's, so the app with the better star average is not the one people write more warmly about.
Zero Duplicates ships an update weekly, LudyActions every 9 days. Both last shipped on November 5, 2026.
