Use cases
Delete duplicate photos on iPhone — the copies and the almost-copies
There are two kinds of duplicates. Exact copies, which iOS can find for you, and the near-duplicates — ten tries at the same photo — which only you can judge. deja is built for the second kind.
Exact copies: the Photos app's Duplicates album
The Photos app gathers copies of the same photo in the Duplicates album: open Collections, scroll down to Utilities and tap Duplicates. Merging a set keeps one photo, with the best quality, and moves the other copies to Recently Deleted. It's built in, and a good first pass.
Near-duplicates: keep the best one
Bursts, retakes and five angles of the same dish aren't copies, so no album collects them. deja doesn't detect them either: it plays your photos in the order you took them, so the tries at the same moment come one after another and the best one is easy to see.
♥ it if it's one you love, and mark the rest with the trash. At the end of the day, delete them all with one confirmation.
Safe to delete
Nothing is deleted until you confirm in iOS's own dialog, and deleted photos wait in Recently Deleted for 30 days. deja works on your library on the device; nothing is uploaded.
Free on the App Store · iPhone, iOS 18 or later
Questions
Does deja find duplicate photos automatically?
No. deja shows your photos in the order you took them, so near-duplicates sit next to each other and you choose which to keep. For exact copies, the Photos app's Duplicates album (Collections, under Utilities) finds them for you.
Is deleting duplicates in deja free?
Yes. Cleaning up is always free with no limit; only reliving uses credit.
