CardShuttle backs up your memory card straight to an external SSD with your iPhone. No laptop, no compromises on safety. WHY CARDSHUTTLE When you shoot photos or video in the field, the card fills up sooner or later. CardShuttle copies it to an external SSD and then verifies every single file against the original by checksum. Not just whether the file is there, but whether it matches exactly. Only then do you format the card with peace of mind. HOW IT WORKS 1. Connect a card reader and an SSD to your iPhone, for example via a USB-C hub 2. Pick the card folder and a destination folder on the SSD 3. Start the backup: CardShuttle copies, verifies and tells you clearly whether everything matches FEATURES • Copy with real verification (xxHash3-128 or SHA-256) • Automatically detect and resume interrupted backups, already verified files are not copied again • Field Mode: a reduced, easy-to-read view while copying, the screen stays on • Preview of card size and free destination space before the transfer starts • Check a backup later, even without the original card • History of all previous backups • Export as CSV or TXT • RAW, JPG and video: files are copied unchanged WHO IT'S FOR Photographers and videographers who need to empty cards on the go before they can keep shooting: weddings, events, documentaries, drone flights or travel. TRY IT FREE Up to 10 GB per backup and three complete test backups for free. CardShuttle Pro (one-time purchase, no subscription) unlocks unlimited backup size, unlimited history, destination checking without the original card, and export. PRIVACY CardShuttle collects no data. Everything stays on your device: no cloud upload, no account, no tracking. Help and guide: tk-craft.de/cardshuttle/en

Verdict
The clearest difference is rating: CardShuttle at 5.0 against Dual Camera's 4.5. Dual Camera's advantage is update cadence (every 10 days vs every 6 weeks) and ratings volume (11 vs 1). On price, review sentiment, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Dual Camera sells 3 in-app purchases, starting at $2.99 per 7 days and CardShuttle sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
CardShuttle holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Dual Camera has 11 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
Dual Camera ships an update every 10 days, CardShuttle every 6 weeks. The most recent releases landed on November 5, 2026 and October 31, 2026 respectively.
