Collect. Document. Show the world — or keep it just for yourself. Start right away: try guest mode first, then create an account later — everything you’ve saved stays with you. After you sign up, your data syncs to the cloud so your collection is always within reach. Stacked is a digital space for people who collect. Not just notes about “what I own,” but a living catalog of your collection: items, ratings, photos, a wishlist, ranking, and a community of collectors. Coins, vinyl, books, stamps, figures, wine — or something entirely your own? In Stacked every collection becomes a neat system: useful for you, and, if you want, interesting to others. WHAT YOU CAN DO • Create collections by category — ready-made themes or your own names • Add items with a title, description, tags, purchase date, and price • Attach photos (camera or gallery) and build an item gallery • Rate items on a scale and sort by importance and quality • Keep a Wishlist with priorities so purchase goals don’t get lost COMMUNITY • Activity feed — new and standout public collections • Likes and views of other collectors’ showcases • Collector profiles, search, and friends • Collection stats: size, ratings, progress Stacked is for anyone who wants order in their collection — and for those who love sharing finds, comparing tastes, and growing as a collector.
