RawCatch: RAW Wireless FTP

Shoot. The RAW lands on your iPhone in seconds. No cables, no JPEG-only hacks. Built for Sony A7 III / A7 IV / α1 and any Alpha that speaks FTP.

Your Sony Alpha already speaks FTP. RawCatch is the receiver Sony forgot to ship.

Take a shot. The full-resolution RAW lands on your iPhone or Mac in seconds — not a downscaled JPEG, not after waiting for the sluggish
Creators' App. RawCatch listens on your local Wi-Fi, accepts the file straight from the camera's built-in FTP transfer, and shows you a
preview with full EXIF before the next frame goes off.

What it does:
• Receives ARW over Wi-Fi via the camera's native FTP transfer • Real-time progress: live byte counter, transfer speed, ETA
• Embedded RAW preview + full EXIF (camera, lens, ISO, shutter, focal)
• Auto-saves to your Photos library (with your permission)
• Delete in the app → also deletes from Photos
• Survives the screen turning off mid-transfer
• One codebase for iPhone and Mac

What it fixes:
• Creators' App has no RAW over the air. RawCatch: RAW first.
• Transfer & Tagging Add-on is JPEG-only and unstable. RawCatch is built on Apple's Network.framework.
• Other FTP server apps die in the background. RawCatch keeps the socket alive.
• Sony's "100MSDCF / 101MSDCF" per-session folders break Lightroom watch folders. RawCatch flattens everything into one destination.

Tested on Sony A7 III. Onboarding includes setup steps for A7 IV, A7R IV/V, α1, A9 II/III, FX3 and a generic fallback for other Sony
bodies.

No subscription. No cloud lock-in. No analytics. No accounts. Files stay between your camera, your device, and your Photos library.
