Local-first photo cleanup

Delete the duplicates.
Keep the photos.

Cullia finds the photos in your library that are exactly identical — the same image saved more than once — and groups them together.

You review each group photo by photo, mark what to keep, and confirm before anything is deleted. Every scan happens on your iPhone.

Cullia planning a cleanup: 3 duplicate groups, 3 photos kept, 5 marked for deletion

What “duplicate” means

Exact means exact.

Cullia removes only pixel-identical copies.

Similar memories stay untouched — a crop, an edit, a re-shoot is a different photo, and Cullia leaves it alone.

Privacy, concretely

Nothing leaves your iPhone

Two screens that say it better than we can: the access request, and the on-device results it produces.

The core

Review, don’t trust.

Every duplicate group opens at full size. Zoom into the detail, flip between the copies, and decide for yourself which one is the keeper. Cullia suggests — you decide.

Space, honestly measured

Each marked photo shows its real resolution and file size, so you know exactly what you’re getting back.

Batch or whole library

Free handles up to 300 photos per batch. Pro scans the entire library in one pass.

No subscription

One-time purchase. Buy it once and keep it — restore on any device with the same Apple ID.

Questions

Before you install

What counts as a duplicate in Cullia?

Photos that are genuinely the same image — pixel for pixel — saved more than once in your library. Cullia deliberately avoids date windows and "looks similar" scoring, so it will never suggest deleting a photo just because it resembles another one.

Will Cullia delete anything on its own?

No. You mark photos yourself, confirm inside Cullia, and then confirm again in the system delete dialog. Removed photos go to the system's Recently Deleted album, where they stay for the usual retention period.

Does it work offline?

Completely. There is no network component in the scanning or reviewing flow — turn on airplane mode and every feature still works.

What if I only grant access to selected photos?

That works too. Cullia analyzes exactly the photos you granted and leaves the rest untouched. You can widen or narrow access at any time in iOS Settings.

Is Pro a subscription?

No — Cullia Pro is a single one-time purchase. It unlocks whole-library scanning and removes the batch limit. If you change phones, tap Restore Purchase in the app with the same Apple ID.
