Too many similar photos? Compare them with KeepOne, choose the shots you want to keep, and confirm what to delete. Organize travel photos, selfies, and sets of shots without guessing from tiny thumbnails.

COMPARE SIMILAR PHOTOS Group visually similar still photos taken close together. Review 1–3 suggested keepers, zoom in on details, change your selection, or skip a group. Favorites are kept by default. You decide what stays.

BROWSE, SEARCH, AND ORGANIZE Filter your library by photo type and search locally by date or type. Manage albums, share through the system share sheet, crop, rotate, adjust brightness, and apply filters. Non-destructive edits can be reverted to the original. Play Live Photos in the full-screen viewer.

CONFIRM BEFORE DELETING Review similar groups individually. For manual deletion, confirm non-favorites first, then review favorites separately. Deletion requires confirmation in the app and the system photo library. Deleted photos are managed in Recently Deleted in Apple Photos. With iCloud Photos enabled, deletions sync to your other devices.

ANALYSIS ON YOUR IPHONE Photo analysis runs on your device. Your photos are not uploaded to the developer. No account is required, and limited photo access is supported. Photos stored only in iCloud are downloaded for similarity analysis only when you allow it.

Download KeepOne and start with one group of similar photos. Requires iOS 17 or later. Supports English, Simplified Chinese, Traditional Chinese, Japanese, and Korean. Similarity analysis works with photos, not videos.
