Photoscope: Best Photo Picker

Photoscope finds similar photos in your library and helps you choose the best shot, not just delete duplicates. It automatically groups bursts and near-duplicate series and guides you with side-by-side comparisons to keep only the top images.

Best for on-device privacy: all processing happens offline with no cloud uploads. It works on iPhone, iPad, and Apple Vision Pro, and it's completely free with no subscriptions. How it works: scan your library, review each series, pick favorites, and delete the rest.
