Cullia: Delete exact duplicate photos. Nothing leaves your iPhone.

Hi Product Hunt 👋 I built Cullia because I kept finding the exact same photo saved more than once in my own library, and I wanted a cleaner that didn’t have to upload my photos somewhere first. Cullia does one thing deliberately: it finds exact duplicates — not photos that merely look similar — groups them, and lets you review every copy before anything is removed. A few choices were important to me: • Everything runs on-device. No account, no cloud, no tracking. • Nothing is deleted automatically. You decide what stays. • Pro is a one-time purchase, not a subscription. The first version is intentionally focused. I’d especially love feedback on the review flow and whether “exact duplicates only” feels like the right boundary. Thanks for checking out Cullia. — EFREM LEE
