SDCull helps you sort photos directly on an SD card, external drive, or folder in the Files app. You do not need to import the photos first. Review photos one at a time or select several from the grid. Mark unwanted photos as culls and mark keepers as selects. Culls move to a _Culls folder. You can review them there before you delete them. Selects move to a subfolder on the card or to another drive or folder. SDCull copies each file and confirms the copy before it removes the original. SDCull supports common photo formats and RAW files, including ARW, CR2, NEF, DNG, and RAF. It can group matching RAW and Non-RAW files so that you can review and move them together. Other features include: • Sort by filename, EXIF capture time, or modification date. • Filter by file type or flag. • Zoom in to inspect detail. • View the camera, lens, exposure, and file information. • Undo flag changes. • Keep flags after you close the app. • Use keyboard shortcuts on an iPad. SDCull works offline and does not require an account.

DataOffloader is the fastest way to move photos and videos from your iPhone to an external SSD. If you shoot a lot of content — whether for work, social media, or personal projects — your iPhone storage fills up fast. Especially with ProRes, 4K, and Cinematic Mode videos. DataOffloader gives you a simple, powerful workflow: browse, select, transfer, done. HOW IT WORKS Connect your external SSD to your iPhone via USB-C. Open DataOffloader. Select the media you want to offload. Tap Move or Copy. That's it. SMART BROWSING See all media from the last 24 hours, 3 days, or 7 days at a glance — or browse your entire library. Navigate your existing albums with built-in search. The default view shows your most recent content, so you can offload today's shoot in seconds. POWERFUL FILTERS Filter by media type: photos only, videos only, ProRes, RAW, Live Photos, Slow-Mo, Time-Lapse, Cinematic, or Screenshots. Sort by newest, oldest, largest file size, smallest, or video duration. Find exactly what you need, fast. FAST SELECTION Tap to select individual items. Swipe across the grid to select many at once. Select All to grab everything in your current view. A live counter shows how many items you've selected and their total size. MOVE, COPY, OR DELETE Move files to your external SSD to free up iPhone storage immediately. Copy files to keep them on both devices. Delete files you no longer need with a double-confirmation safety net. DataOffloader preserves original file quality — no compression, no conversion. BUILT FOR CREATORS Whether you're a filmmaker shooting ProRes on iPhone, a photographer managing RAW files, or a content creator clearing space between shoots — DataOffloader is the tool you've been missing. Requires an iPhone with USB-C connector and an external storage device.
