StashIQ is the pocket companion for plastic scale model builders and collectors. Whether you build aircraft, armor, ships, cars, figures, or sci-fi, StashIQ helps you catalog what you own, plan what you want, and never buy a duplicate kit again. BROWSE A HUGE CATALOG Search a catalog of 88,000+ scale model kits across every major manufacturer, scale, and subject. Find the exact kit, see its details, and jump straight to retailers when you're ready to buy. SCAN TO IDENTIFY ANY KIT Point your camera at a kit's barcode and StashIQ identifies it instantly — then add it to your stash or want list in one tap. Can't find it? Share a link or add it manually, and it gets reviewed to grow the catalog for everyone. TRACK YOUR STASH Log every kit you own in one organized place. Know your collection at a glance — no more standing in a hobby shop wondering if you already have that Spitfire. BUILD A WANT LIST Keep a running wish list of the kits you're after. When you're browsing or scanning, you'll always know what's still on your list. FIND THE BEST PRICE See where to buy the kits you want and compare retailers, so you can grab the deal when it's right. MADE FOR MODELERS StashIQ was built by scale modelers who were tired of tracking their stash in spreadsheets. It's fast, focused, and designed around how hobbyists actually shop and build.
