SDCull

Clean up an SD card full of photos, quick!

I built SDCull because I wanted to take advantage of the amazing displays on my iPad and iPhone when culling on the go, but I prefer to do my editing at home on a desktop. SDCull lets photographers sort a shoot right off the card — flag the rejects, pick out the keepers, and send each set exactly where you want it, all without importing a thing.

Two workflows, one pass through your shoot:
- Cull: Flag the "rejects" and move them to a _Culls folder — a safety net you can review one last time, then delete to reclaim space.
- Select: Flag your keepers and move them straight to a destination of your choice — a subfolder on the card, or another drive or folder on your device. Selects are never deleted; they're the shots you're keeping.

Designed with efficiency in mind:
1. Connect: Plug in your SD card reader, or open any folder on your device.
2. Review & Flag: Swipe through one photo at a time, or tap Select to flag in bulk. A Cull / Select switch lets you choose what each tap does.
3. Move & Clear: Move all flagged photos to their destination in one tap. Review your culls one last time, then delete to reclaim storage immediately.

Key Features:
- Two workflows: Cull the rejects and gather the keepers in the same pass.
- Flexible select destinations: Send keepers to a subfolder on the card, or out to another drive or folder on your device.
- Direct SD Card Access: Works directly with SD cards and external drives through the Files app. No import required.
- RAW Support: Native support for ARW, CR2, NEF, DNG, RAF, and more, alongside standard JPG/HEIC.
- Safe by design: Files are copied and verified at the destination before the original is removed, so a photo is never lost mid-move. Culls wait in a _Culls folder before anything is deleted, and moves preserve your subfolder structure so same-named files never collide.
- Undo and session memory: Step back through flag changes with undo (Cmd+Z on a keyboard), and pick up right where you left off — flags survive closing the app.
- Built for judging photos: Zoom in for a sharpness check with extra detail loaded on demand, and flip open the info overlay for capture time, camera, lens and exposure settings.
- Sort and filter your way: Order by filename or date (EXIF capture time or last-modified — your choice), filter by file type, or focus the grid on just your culls, selects, or unflagged shots.

I use this after every one of my shoots, and I hope you will too!
