DISCDEX tells you what your physical movie collection is actually worth — and makes building that collection effortless. Point your camera at a disc's barcode and DISCDEX adds it to your shelf in seconds. No typing UPCs, no hunting for titles. Then price your collection from real eBay sold listings, so the value reflects what discs genuinely sell for — not a list price nobody pays. WHY COLLECTORS USE DISCDEX • Scan to add — use the camera to catalog a whole shelf fast, by barcode. • Real-world values — pricing comes from actual eBay sold listings, updated when you price a title. • New vs. used — see both, and track which condition you own. • Slipcover-aware — filter pricing for slipcovers when they change the value. • Multiple collections — separate your Owned, Wishlist, or For Sale shelves, and keep a running total of what everything's worth. • Import in bulk — already catalog on Blu-ray.com? Export your CSV and import it as-is. Export back to CSV anytime. • Ten themes — dress the app in a look that suits your shelf. BUILT FOR PHYSICAL MEDIA DISCDEX is for people who still love owning the disc — Blu-ray, 4K UHD, and DVD. Whether you're insuring a collection, deciding what to sell, or just curious what that shelf adds up to, DISCDEX gives you a clear, current number. Your collection is private to your account. No ads, no tracking, no selling your data. Free to start. Get the app, scan your first disc, and watch your shelf's value take shape.
