Cullia
Cullia finds exact duplicate photos in your library, groups them, and lets you review each group photo by photo — mark what to keep, exclude the rest, and delete only after you confirm. Every analysis happens locally. Nothing is uploaded, synced, or shared.
What Cullia does
Exact duplicate groups
Automatically groups photos that are identical at the pixel level — true duplicates — so you can review them together and keep one.
Review each group
Look through each group photo by photo: swipe between photos, pinch to zoom into details, then mark every photo keep or delete. Undo is one tap away.
Explicit delete only
Deletion happens only after you mark photos and confirm — first in Cullia, then in the system photo delete dialog. Photos go to Recently Deleted, where you can restore them.
Free scan · Pro whole library
Free scans up to 300 photos per batch. Cullia Pro (one-time purchase) scans your entire library with no scan limits.
On-device analysis
Duplicate detection runs entirely on your iPhone — no uploads, no cloud processing.
Private by design
No servers, no analytics, no tracking, no accounts. Your photos and your library never leave your device.
How it works
- Grant library access. Cullia reads your photo library with your permission — full access or selected photos.
- Cullia analyzes on-device. Exact duplicate groups are found locally, in seconds.
- Review and mark. Look through each group, zoom into details, and mark every photo keep or delete. Undo freely.
- Confirm to clean up. Only the photos you marked are deleted, after your confirmation in Cullia and the system photo delete dialog.
