Lyn
A lightweight Mac media browser and image viewer from Mirko Viviani aimed at photographers and designers who need to cull large folders, inspect RAW files, and apply quick adjustments without importing everything into a heavy catalog app.
Typical Mac workflow
You point Lyn at a folder, external drive, or camera card and browse with four configurable views, ratings, keywords, color tags, and smart folders. Double-click opens the viewer or a fullscreen slideshow; the inspector shows IPTC metadata, EXIF, and editable fields you can batch-update across selections. Non-destructive edits—exposure, curves, levels, HDR, selective color, B&W, sepia, vignette, and film grain—are stored as attributes and baked in on export, leaving originals untouched.
Lyn reads JPEG, PNG, TIFF, HEIC, HDR, JPEG XL, AVIF, SVG, common camera RAW formats, QuickTime clips, and simple PDFs. You can browse Photos, Lightroom, Aperture, and iPhoto libraries, geotag shots on a map with drag-and-drop, and share to Flickr, Dropbox, or SmugMug. Color-managed preview and soft-proofing help when you are preparing files for print.
Licensing and version 2.4.10
Lyn sells for about $29.99 through FastSpring on lynapp.com with a 15-day full trial and roughly 15 months of free updates per vendor listings; it is not distributed on the Mac App Store. Version 2.4.10, released 9 July 2026, is a small maintenance build that fixes intermittent equivalent keyboard-shortcut issues. It requires macOS High Sierra 10.13.4 or later and is listed as ready for macOS Sequoia and Tahoe.
