SD Import is the fastest and simplest tool to import photos and videos from your camera SD card directly to iPhone Photos. Why SD Import? • Real-time import progress — see exactly how fast files are transferring, byte by byte • One-tap card cleanup — delete successfully imported files from your SD card right after importing, freeing space while you're still shooting (Pro) • Deletion with two safeguards — only files verified as fully read and confirmed saved to Photos are removed; failed imports are never deleted, and every deletion needs your confirmation • RAW format support — ARW, CR2, CR3, RAF, NEF and more • Smart scanning — automatically finds photos and videos, hides junk files • Date grouping — browse media organized by shooting date • EXIF preserved — original shooting dates kept intact in your Photos library • Storage check — warns you before import if space is running low How it works: 1. Connect your SD card reader to iPhone 2. Select the SD card directory 3. Pick your photos and videos 4. Tap Import — done! 5. Need space? Clear the imported files off the card in one tap About the delete feature Every file is verified as fully read and successfully saved to your Photos library before it is deleted. Files that failed to import, or that you didn't select, are never touched. Deletion always requires an explicit tap plus a confirmation — nothing is ever deleted automatically. Pro upgrade unlocks unlimited imports and SD card cleanup with a one-time purchase. No subscription, yours forever. Supports Sony, Canon, Fujifilm, Nikon, DJI and other major camera brands.

Verdict

The call

The clearest difference is in-app purchases: OTG Flash Pro at none against SD Import's 1. OTG Flash Pro also leads on iOS requirement (14.0 vs 16.0). SD Import's advantage is update cadence (every 2 days vs every 10 days). On price, ads and device support there is nothing between them.
