MatchGrain: Film EXIF Log

Every frame you shoot deserves its data. MatchGrain is the film photography logbook built for one thing other apps can't do: writing real EXIF metadata into your scanned negatives — entirely on your iPhone. No Mac, no desktop software. Shoot the way you always have. Log each frame in seconds — aperture, shutter, focal length, the lens you used. When your scans come back from the lab, MatchGrain embeds that data straight into the files, so your archive finally knows what your camera always did. Reasons to use: • iPhone-native EXIF embedding — scans carry correct aperture, shutter, ISO, focal length, location and date, readable in Lightroom, Photos, and anywhere else. • Frame-by-frame logging — capture settings as you shoot, before you forget them. • Your gear, your way — set up cameras and lenses once, including fixed-lens bodies. • Roll-based workflow — organize by roll, the way you actually shoot. Built by a film shooter, for film shooters. No spreadsheets. No notebook left at home. No Mac tethering. Just your camera, your phone, and metadata that finally matches.
