I wish I had something like this for my iPhone that would automatically soft delete duplicate photos, picking out the sharpest one. Maybe an app exists already but I haven’t looked super deep for it.
Not exactly the same but for Burst Mode photos (where they all start grouped together) it will automatically pick what it thinks is the best one, and you can:
- Go to the burst in the photo roll
- Tap "Select..."
- Pick one (or more)
- Tap Done
- Tap "Keep Only 1 Favorite" to get rid of the others you didn't select.
