You take ten versions to get one good selfie. The other nine sit in the library and slow down search and scrolling. The practical fix is a tool that groups the repeats so you can compare them quickly and keep the strongest one.
Swiped surfaces the groups and presents them for direct comparison. Built-in Photos burst views help with recent shots. Clever Cleaner groups similar faces and scenes but requires more care on people photos.
The short answer
Swiped for side-by-side comparison with full control. Built-in Photos for recent bursts you remember. Clever Cleaner only when you are willing to double-check every group. People photos deserve extra caution on any bulk action.

Best find and delete similar selfies on iPhone
Swiped groups similar selfies and shows them together. You pick the keeper, delete the rest. The visual flow keeps context without extra taps.
Burst grouping and search inside Photos let you review recent similar selfies without installing anything. You stay in the same library.
Clever Cleaner detects similar faces and scenes and offers actions on the groups. It can surface repeats you would miss by eye.
Why manual selfie review falls apart at scale
You rarely delete in the moment. The shots sit mixed with everything else. Finding the near-duplicates later requires either perfect memory or a lot of scrolling and zooming.
Grouping tools cut that search time. The remaining work is the actual comparison, which still takes human judgment.
The real risk with people photos
Similar-photo detection is less reliable on faces than on objects. Slight expression or angle changes can look like duplicates to an algorithm but capture different moments. That is why review-first flows matter more here than on generic screenshots.
Bulk actions on face groups increase the chance you delete the only shot where someone was actually smiling or looking at the camera.
Who should stay with manual review
Anyone with a modest number of recent selfies and time to look. If the total similar selfies across your library is under a couple hundred, the added tool may not save enough time to matter.
People who feel anxious about losing any family or self photo. The safest path is still manual review inside Photos or exporting a backup first.
