Your camera roll is out of control. Purge fixes that. Purge scans your photo library on-device, automatically groups duplicates, near-identical bursts, screenshots, and forgotten shots, then shows each group as a clean grid. Tap the ones you don't want. Hit trash. Done. It's the fastest way to reclaim gigabytes you didn't know you had — without spending a weekend scrolling. No cloud storage of your photos. No account required. Your photos never leave your iPhone. — WHAT PURGE DOES — • SMART GROUPING — On-device intelligence finds duplicates, near-duplicates, burst shots, blurry frames, and screenshots, and sorts them into tidy clusters. • TAP TO MARK — Every cluster opens as a grid. Tap the photos you want gone; the rest stay. No one-at-a-time grind. • PINCH TO COMPARE — Zoom in on any shot and flick through similar ones to pick the keeper before deleting the rest. • TIMELINE VIEW — Walk through your library day by day and see exactly what you shot, when. • STREAKS & PROGRESS — Build a cleanup habit. Track photos removed, space reclaimed, and days in a row. • SAFE BY DEFAULT — Nothing is deleted until you confirm. Everything goes through the iOS trash, recoverable for 30 days. — BUILT FOR PRIVACY — Purge runs entirely on your device. Scanning, grouping, and image analysis all happen locally using Apple's Vision framework. Your photos are never uploaded and never leave your iPhone. — WHO IT'S FOR — • People whose "Storage Almost Full" warning has become a lifestyle. • Anyone with thousands of screenshots they've never looked at twice. • Photographers drowning in near-identical bursts. • Anyone who wants a calmer, lighter camera roll. Stop scrolling past the mess. Purge it. Available in English, French, and Russian.
