ShutterSnitch

ShutterSnitch is a subscription-based photo & video workflow app for iOS. The first week is free, allowing you to verify compatibility with your camera or Wi‑Fi card. It can wirelessly transfer images from Eye-Fi, Transcend, Toshiba FlashAir, PQI Air, ez Share cards, GoPro HERO, Fujifilm cameras with built-in Wi‑Fi, PTP/IP devices, and more. When a JPEG arrives, ShutterSnitch analyzes shutter speed, aperture, ISO, focal length, and light level and warns you if anything differs from the rules you've set up.

You also get a large preview screen you can browse, pinch, zoom, and evaluate seconds after snapping your picture. In studio environments it's easy to share shoots with crew and models. Other features include Retina display support, non-destructive edits, metadata presets, albums and private albums, resizing and watermarking before sharing, and options to share via email, Dropbox, Flickr, FTP, WebDAV, Google Drive, OneDrive, SmugMug, and Zenfolio. The app also supports AirDrop export and Bonjour discovery. Subscription payments are $2.99 monthly or $29.99 yearly and renew automatically; setup for devices outside the app can take more than a few minutes.
