Silo Sweep: Photo Duplicates

Silo Sweep reviews the photo library on your iPhone or iPad for near-duplicates, burst runs, blurry frames, screenshots, screen recordings and large videos, then waits for your decision on each one. Near-matches are grouped around one keeper. A photo joins a group only if it resembles that group's keeper directly, never through a chain of in-between shots, so a slowly changing sequence is not collapsed into one pile. Two items are called exact duplicates only when a SHA-256 digest of their real image data matches, including a Live Photo's video and any edited version. Swipe to keep or toss. Each group always keeps at least one photo. Photos you toss go through Apple's own confirmation and then stay in Recently Deleted for 30 days, so you can change your mind. After a sweep, Silo Sweep reads the library back and reports what actually moved, what was already gone, and what it could not check. With Limited Library access it says so instead of guessing. A queued photo is never counted as deleted, and you can export the record as a CSV file. Want to see how it works before granting Photos access? Open the built-in sample library.
