Duplicatus

Duplicatus is a storage-cleaning app for iOS whose App Store listing is titled Photo Cleaner AI: Duplicatus. It targets the most common cause of a full gallery: dozens of near-identical shots of the same moment, blurry misfires, and large videos that were never watched twice. Rather than asking you to scroll manually, it analyzes the library and presents grouped results you can act on in bulk.

The core workflow is comparison and removal. Similar photos are clustered so you can see them side by side and keep the sharpest or best-framed one; a separate section lists unsuccessful shots such as blurry or out-of-focus images; and videos can be sorted by size to surface the largest files first. A swipe-to-delete mode and date or size sorting round out the cleanup experience, and the app also helps you clear photos and videos cached by messenger and social apps.

The app is a solo-developer project by Alexander Petrovichev, who states he built it because he kept running out of space himself. It requires iOS 13.0 or later and works across iPhone, iPad, iPod touch, and Apple silicon Macs and Apple Vision. Ratings are strong for a utility of this size, with a 4.7 average across roughly 39 ratings, and recent reviews praise how practical the cleanup flow is. The developer is the sole author and has shipped updates over time. It is free to use with optional Premium subscriptions or a lifetime unlock.
