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.
