RollKeep
Read full descriptionHide full description
RollKeep finds similar shots, blurry photos, screenshots and huge videos, keeps the best of each, and lets you clear the rest in minutes. It all runs on your iPhone, and nothing is deleted until you say so. SIMILAR PHOTOS Bursts and near-identical shots are grouped automatically. The keeper is chosen for sharpness, faces and composition, and RollKeep tells you why it picked it. Every pick is yours to change. - Memes on the same template and edits of one photo stay separate - Favorites and albums you protect are never touched - Blurry photos are split into "definitely blurry" and "maybe on purpose", and only the first is pre-selected CLEAN EVERYTHING The safest picks across similar photos, screenshots and blurry shots on one screen, each with the reason it's safe to clear. Skip a whole category, or open one and choose photo by photo. Large videos and Live Photos get their own screens. SWIPE MODE, FREE FOREVER Go through your library one month at a time: right to keep, left to toss. Undo anything, save the maybes for later, and pick up where you stopped. Nothing is deleted until you review the stack. VIDEOS AND LIVE PHOTOS Compress large videos with a before and after preview, and keep the original if you want both. Turn Live Photos into stills and keep the photo, its date, location and albums. SPACE YOU CAN VERIFY iPhone keeps deleted photos in Recently Deleted for 30 days, so your storage won't change right away. RollKeep shows you how to empty it, then measures your free space before and after, so you see real gigabytes back, not an estimate. HOME SCREEN WIDGETS Storage shows free space and how much RollKeep can give back. On This Day brings back a photo from years ago. Streak keeps your weekly tidy going. PRIVATE BY DESIGN Scanning uses Apple's on-device Vision framework. No account, no uploads, no analytics, no ad trackers. WHAT ROLLKEEP WILL NEVER DO No fake speed boosts or cache cleaning, no "storage almost full" alarms, no weekly subscriptions, and no hidden close buttons. Every deletion needs your tap and Apple's own confirmation. ROLLKEEP PLUS Swipe mode, screenshot, screen recording and large video cleanup, and widgets are free. Plus adds similar-photo detection with best-shot picking, Clean Everything, blurry and Live Photo cleanup, and video compression. - Clean Pass: one payment for 72 hours of Plus. It never renews. - Annual: yearly subscription with a 7-day free trial. Renews automatically unless cancelled at least 24 hours before the end of the period. Manage or cancel in Settings > your name > Subscriptions. - Lifetime: pay once, keep Plus forever.
