Storage full again? Photos app cluttered with duplicates, burst shots, and screenshots you forgot about? This duplicate cleaner finds every copy hiding in your photo library and across your Files app, so you can free up gigabytes in minutes instead of hunting through albums one by one. Built for iPhone and iPad. Optimized for huge libraries. Runs entirely on-device. WHAT IT FINDS Exact Duplicates. The fast hash engine catches byte-for-byte identical photos. Same shot saved twice, three times, ten times. Whether it came from a backup, a chat thread, or an import gone wrong, the duplicate finder spots it in seconds. AI Similar Photos. Vision AI compares photos visually, not just by file. Burst shots from the same second. Edited copies. Cropped versions. The same scene from slightly different angles. The neural matcher groups them so you can pick the keeper and clear the rest. Screenshot Cleanup. Hundreds of duplicate screenshots from web articles, receipts, and chats. The scanner targets the screenshots folder and surfaces duplicates fast, so your gallery stops looking like a hoarder's notebook. Files and iCloud Scanning. Pick any folder in the Files app, scan iCloud Drive, dig through a downloaded archive. Documents, PDFs, photos, anywhere duplicates pile up, the cleaner reaches them. HOW IT WORKS Pick what to scan: photo library, screenshots, or Files. Choose a mode: exact match or AI similarity. Review groups with side-by-side previews. Auto-select duplicates or pick your own. Delete and watch the gigabytes come back. Originals always stay protected. Deleted photos go to Recently Deleted first, so nothing is gone for good unless you say so. SMART FEATURES Adaptive Performance scans adjust to device state, so battery and heat stay in check. Memory Management handles tens of thousands of photos without choking. Gallery View shows large previews for quick visual confirmation. Auto-select pre-picks copies and keeps the best. The adjustable AI threshold lets you tune how strict the similar-photo matcher gets. Skip Hidden Files ignores system files and hidden folders. Dark and light themes match your iOS appearance. Scan notifications ping you when a long scan finishes. Performance tuning controls concurrent operations for your device. The iPad layout uses sidebar navigation and large previews, built for the bigger screen. BUILT FOR People who shoot a lot and review never. iPhone owners staring at the Storage Almost Full warning. Anyone prepping for an iOS update and short on space. iPad users with years of Files app downloads. Parents whose camera roll is 80 percent the same toddler photo. Designers and photographers who need clear space for new work. PRIVACY FIRST Everything runs on your device. No cloud processing, no photo uploads, no tracking. The AI runs locally using Apple's Vision framework. Your photos and files never leave your iPhone or iPad. Period. WHY THIS CLEANER Most duplicate finders catch the obvious copies and stop there. This one goes further. The AI catches near-duplicates that file-size matching can never see. The screenshot mode targets a folder most apps ignore. Files app integration covers iCloud Drive, downloads, and folders the Photos app cannot touch. Adaptive performance works as well on an iPhone SE as it does on an M-series iPad. Free scan included. See how much space you can recover before you commit. Premium unlocks unlimited cleanup, larger scan limits, and AI similarity scans across the full library.

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.
