CleanTwin Smart Duplicate Finder

Reclaim gigabytes in minutes. CleanTwin uses on-device AI and lightning-fast hashing to find exact and near-identical photos, videos, and files - then helps you remove them safely.

Works on internal drives, external disks, and your photo library. Built for iPhone, iPad, Mac, and Vision Pro - your files never leave your device.

Everything You Need to Free Up Space

CleanTwin pairs ultra-fast byte-perfect hashing with AI image similarity, so you catch the duplicates a human eye would never spot.

Lightning-Fast Hash Scan

Multi-threaded engine analyses 1000+ files per second on internal drives, external disks, and the Photos library.

AI Similarity Detection

Vision-powered analysis groups near-identical photos and videos - bursts, edits, exports, and re-saved screenshots.

Smart Auto-Select

Keeps the best original (highest resolution, newest, RAW vs JPEG) and marks safe duplicates for removal in one tap.

Storage Insights

Live dashboard shows how much space duplicates waste and how much you reclaim after each clean.

External Drives & NAS

Scan any mounted volume on Mac - external SSDs, USB sticks, SMB/NAS shares - and dedupe across them.

Photos Library-Aware

Works hand-in-hand with Apple Photos on iPhone, iPad, Mac, and Vision Pro - safely removes duplicates without breaking albums.

Safe Cleanup

Move duplicates to Trash or a backup folder - nothing is deleted permanently until you say so.

100% On-Device

Hashes and AI analysis run locally. Your photos, files, and metadata never leave your device.

Bulk Actions

Sort groups by size, count, or date - select hundreds of duplicates at once and free real gigabytes instantly.

How CleanTwin Works

Three simple steps - everything runs on your device, no setup, no accounts.

1. Scan

Point CleanTwin at a folder, drive, or your Photos library. The multi-threaded engine computes byte-perfect hashes locally - your data never leaves your device.

2. Review

AI groups identical and visually similar files side-by-side. Preview every match, see resolution and date, and pick what to keep with one tap.

3. Clean

Send selected duplicates to Trash (or a backup folder on Mac). Watch the storage gauge climb back up as gigabytes return to you.

Built for iPhone, iPad, Mac & Vision Pro

A native experience on every Apple device, accelerated by the Neural Engine and Apple Vision framework.

Perfect For

Photographers and creators with years of bursts, edits, and re-imports cluttering iCloud Photos.
Mac power users running low on disk space because of duplicate downloads, backups, and exports.
Anyone with multiple external drives or a NAS where the same files have piled up over time.
Parents and families sharing a photo library full of near-identical kid pics.
Privacy-minded users who refuse to upload their photo library to a third-party "cleaner" service.

What Makes It Different

Real AI similarity: Vision-based image fingerprints, not just byte hashes.
100% on-device: nothing uploaded, nothing tracked - your library stays yours.
Native on every Apple device: iPhone, iPad, Mac, and Vision Pro, not a stretched build.
Smart auto-select: keeps the highest-quality original so you never delete the wrong one.
Safe by design: nothing is permanently removed until you confirm.
