SDCull vs QSDC

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.
