Duploop

Duploop finds the duplicate and near-duplicate photos hiding in your camera roll — exact copies, rotated versions, cropped re-saves, and near-identical shots from the same burst — and helps you clean them up in a few taps. If you've got years of photos and know there are duplicates buried in there somewhere, Duploop is built for you. Every scan runs entirely on your device using Apple's Vision framework — your photos are never uploaded anywhere, and Duploop doesn't need an account or an internet connection to work. HOW IT WORKS • Scan your library once — Duploop fingerprints every photo and groups the redundant ones together • Review side by side — each group shows a comparison view with a similarity score, resolution, and date • Keep the best, delete the rest — Duploop recommends the highest-quality copy to keep automatically • Watch the space add up — see exactly how much storage each cleanup freed, and track it over time THREE WAYS DUPLOOP FINDS DUPLICATES • Exact duplicates — byte-identical files, however they got copied • Rotated copies — the same photo saved again after a rotation • Similar photos — near-identical shots from the same scene or burst, scored by confidence BUILT FOR A QUICK CLEANUP, NOT A CHORE • Fast side-by-side comparison with file size and capture date for every photo • A running history of past cleanups and total space freed • Adjustable sensitivity, from strict exact-only matching to a looser similar-photo net Duploop is a one-time purchase to unlock unlimited similar-photo review and history export — no subscription, ever.
