DupFinder
Buy lunch, not a cleaner app
About
This app identifies exact duplicate files, photos, videos, and contacts using content fingerprinting. It also helps manage similar shots, blurry photos, large files, and screenshots, all processed locally for privacy.
What's New in DupFinder
1.16
September 8, 2026
DupFinder now runs on iPad. A sidebar puts all nine tools one tap away — Exact, Similar, Blurry, Screenshots, Large, Review by Month, Files and Contacts no longer hide behind cards. Grids use the wider screen instead of stretching three columns across it, and swipe-to-review is tuned so a nudge no longer counts as a decision. Everything still runs on your device. No accounts, no analytics, no uploads.
