Cull, rate, and tag thousands of photos fast, straight from your Synology NAS, the Apple Photos library on your iPhone and iPad, an SD card or external SSD, any network share over SMB, or a local folder on your Mac, iPad, or iPhone. Now with on-device AI that scores every frame, groups bursts, and suggests your keepers. Ratings, keywords, and captions sync to Lightroom and Capture One via XMP. No desktop step, no cloud, no lock-in. CullKit turns any photo source into a focused review tool. Point it at Synology Photos, your Apple Photos library on iPhone and iPad, a mounted NAS share, an SD card straight out of the camera, an external SSD, or a folder on your device, then rip through a shoot, mark keepers with stars, and let your ratings and metadata write back to XMP sidecars so Lightroom, Capture One, and Darktable pick them up automatically. AI culling, right on your device • Every photo gets on-device scores for sharpness, faces, eyes open, and overall quality • Bursts and near-duplicates are grouped, with the best shot suggested and side-by-side compare • Auto-cull pre-selects keepers and rejects in one tap; every suggestion is revertible • Filter and sort by AI verdict, check key faces up close, zoom to full quality • A cull intensity slider decides how strict the AI is: keep more or keep less • All analysis runs on your iPhone, iPad, or Mac.

Each AI verdict, blurry, eyes shut, low quality, becomes a reject, a star rating, or no change at all. Set the table once in Settings and auto-cull follows it. Badly out-of-focus shots and eyes-shut frames get proposed as rejects even when they are not part of a burst. Before, the app labelled a photo blurry and then gave it two stars anyway. Suggestions still land in the review grid first, and Discard puts everything back. Connect over HTTP Manual connections now offer an HTTPS or HTTP picker. If your DSM only serves plain HTTP on the LAN, you can browse and cull without turning on HTTPS at the NAS. Two-factor login works over HTTP too. HTTPS stays the default. Much faster on Mac Switching folders or tabs no longer pins a core while the whole photo cache gets scanned. Timeline and album views load only the photos that belong to them. Fixed - Culling from an SD card lost decisions when you pressed Save - The photo grid came up blank on folder and SMB connections - Clear Cache left the app in a broken state - Deleting or moving a RAW + JPEG pair left the RAW file behind - Whole folders went missing over SMB when a directory could not be read - Picking one frame in a group left its siblings with no rating - A failed sync showed an empty sidebar instead of the error - AI culling offered itself on devices that cannot run it Everything still runs on your device. No photo leaves it. ### 1.6.0 — 2026-08-10 Reject, hearts, and colour labels are proper culling states now. Swipe left to reject a photo without touching its stars, and rate, favourite, and label it in the same pass. Reject is its own state. A genuine one-star photo stays a genuine one-star photo, and Restore gives the old rating back. Rejects go into your XMP sidecars with the standard reject value, so Lightroom sees them as flagged rejects. Hearts and colour labels work the same way. Each has its own swipe direction, and each writes back to Synology Photos and to your sidecars. You decide what every direction does, including nothing at all. Moves wait for Save Folder moves and album adds no longer happen mid-cull. Work through the shoot, check the summary, then commit the lot when you press Save. Until then your NAS is untouched. Better on Mac - The same keyboard shortcuts in the grid, the viewer, and culling - The culling review opens from the grid, so Done no longer leaves you stranded - Move a collapsed group and all of it moves, not just the suggested pick Also fixed - Mirrored deletes in Apple Photos picked the wrong asset and skipped videos - The card flashed black when a swipe brought up the next photo - Swipes could snap back instead of committing - The favourites filter did nothing in the grid - Groups of similar photos kept reopening as you scrolled - Blurry RAW thumbnails in local folders Everything still runs on your devices. No photo leaves it. ### 1.4.0 — 2026-07-27 AI culling is faster now, and one bad bug is gone. Auto-cull used to crawl on large folders because it saved every photo one at a time. It now applies your whole shoot in a single pass at the end. On an Apple Photos library it could also stop dead at "Analyzing 0 of ..." and never recover. Fixed. The bigger one: photos could end up marked for discard no matter which way you swiped or what rating you gave them. If a burst was grouped too loosely, a single swipe spread across the whole group and the remaining frames were skipped past. Ratings now stay on the photo you rated. Also fixed and improved - Grouping strictness now controls how close together in time frames must be, as well as how alike they look - Make Pick hands the previous pick's stars to the new one instead of clearing them - Tap the star, keeper, or reject badge in the review screen to filter by it - Cleaner photo grid with the AI overlays removed - Grouped shots get a filmstrip in the viewer, matching the review screen - The review summary no longer appears without its background Everything still runs on your device. No photo or score leaves it. ### 1.3.0 — 2026-07-21 CullKit can now cull for you. On-device AI scores every photo, groups bursts and near-duplicates, and suggests keepers and rejects. You review, adjust, and apply. New - AI Assist: on-device scores for sharpness, face quality, eyes open, and aesthetics on every photo - Auto-cull: one tap suggests star ratings and rejects for the whole shoot; every suggestion is revertible - Burst and duplicate grouping with a suggested best shot, side-by-side compare, and full-quality zoom - Review screen with AI verdict filters, key faces close-ups, and a summary of what was kept and why - Cull intensity slider: keep more or keep less, you decide how strict the AI is Everything runs on your device. No photo, score, or decision ever leaves it. ### 1.2.8 — 2026-06-27 Browse your library even without a NAS connection. Plus: edit keywords, captions, and copyright that write to XMP for Lightroom and Capture One. New - Offline browsing: your photos stay accessible when your NAS or network is unreachable - Edit keywords, captions, and copyright directly in CullKit; changes write to XMP sidecars that Lightroom, Capture One, and Bridge read - Every photo now gets a standard XMP sidecar so star ratings and colour labels stay portable across desktop tools Improved - Faster, sharper full-screen RAW previews: CullKit reads the embedded preview so big shoots fly by without waiting on full-size decodes - Apple Photos grid loads faster; thumbnails appear right away when you reopen the app - Smoother switching between online and offline; CullKit detects connection changes and recovers without restarting Fixed - Keyboard no longer covers the keyword field on iPhone and iPad ## Apps similar to CullKit | App | Rating | Price | Category | | --- | --- | --- | --- | | [Cull: Photo Picker](https://appshunter.io/ios/app/cull-photo-picker/id6766058341) | — | Free | Photo & Video | | [Photo Triager: RAW Culling](https://appshunter.io/ios/app/photo-triager-raw-culling/id6760640388) | — | Free | Photo & Video | | [cullstudio](https://appshunter.io/ios/app/cullstudio/id6753145956) | — | Free | Photo & Video | | [SDCull](https://appshunter.io/ios/app/sdcull/id6757115890) | 5.0 (2) | Free | Photo & Video | | [Photo Workflow - CaptureBuddy](https://appshunter.io/ios/app/photo-workflow-capturebuddy/id6759609968) | — | Free | Photo & Video | | [SwipeCull: Photo Cleaner](https://appshunter.io/ios/app/swipecull-photo-cleaner/id6765848798) | — | Free | Photo & Video | ## More apps by idyation GmbH - [Kite Size Calculator](https://appshunter.io/ios/app/kite-size-calculator/id1456801209) - [HighFive: Contact Journal CRM](https://appshunter.io/ios/app/highfive-contact-journal-crm/id6752213281) All apps by idyation GmbH: https://appshunter.io/developer/1421286534 ## Related topics [nas photo](https://appshunter.io/ios/topics/nas-photo) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
