About

Deduply

Your camera roll is full of copies you never meant to keep β€” burst shots, near-identical selfies, re-saved screenshots, forwarded videos. Deduply finds them all, picks the best one to keep, and clears the rest so you get your storage back. Every scan runs on your iPhone. Nothing is ever uploaded. FIND EVERY DUPLICATE & LOOK-ALIKE Deduply scans your entire library and groups it two ways: exact duplicates that are 100% safe to remove, and look-alike photos and videos β€” the burst shots and near-misses you take three of and only need one. Photos and videos both, with a tap to filter between them. KEEP THE BEST, DELETE THE REST For every group, Deduply automatically suggests the best version to keep so you don't have to compare frame by frame. Review a group in one screen, change the keeper if you disagree, and remove the rest in a single tap. SEE EXACTLY HOW MUCH YOU SAVE A live count shows the space you can reclaim before you delete anything, and a running total tracks every gigabyte you've already freed. Cleaning your library finally feels rewarding instead of tedious. CLEAN UP IN BATCHES Select whole sections at once and clear hundreds of duplicates in seconds. The largest space-savers float to the top, so you free the most storage with the least effort. 100% ON-DEVICE, ALWAYS PRIVATE All scanning and matching happen on your iPhone using Apple's own frameworks. Your photos and videos never leave your device, there's no account to create, no ads, and no tracking. SAFE BY DESIGN Deduply never deletes anything permanently. Removed items go to your Photos "Recently Deleted" album, where iOS keeps them for 30 days β€” so you're always in control and can recover anything you change your mind about. WHY DEDUPLY β€’ Finds exact duplicates and similar photos and videos β€’ Auto-picks the best copy to keep in every group β€’ Live reclaimable-space counter and lifetime savings tracker β€’ Fast batch selection and one-tap cleanup β€’ 100% on-device β€” nothing is uploaded β€’ No account, no ads, no tracking β€’ Safe deletes via Recently Deleted (recoverable for 30 days) β€’ Designed for iOS β€” fast, private, beautiful For everyone whose photo library has outgrown their storage β€” reclaim your space in minutes, keep only the shots that matter, and never pay for an iCloud upgrade you didn't need. SUBSCRIPTION TERMS Deduply is free to download and includes a limited number of free cleanups so you can try it risk-free. Deduply PRO unlocks unlimited cleanups and batch delete with one of two auto-renewing subscriptions: β€’ Yearly: $39.99 USD / year, with a 3-day free trial. After the trial, your subscription automatically converts to a paid yearly plan unless cancelled at least 24 hours before the end of the trial period. β€’ Weekly: $7.99 USD / week (no free trial). Payment will be charged to your Apple ID at confirmation of purchase. Your subscription renews automatically at the same price unless auto-renew is turned off at least 24 hours before the end of the current period; the account will be charged for renewal within 24 hours prior to the end of the current period. Local prices may vary by region; the exact price for your region is shown in the in-app subscription tile. You can manage and cancel your subscription anytime in your Apple ID Account Settings.
