ShadowTag: Easy Label Printer

ShadowTag turns the worst part of being a trading card vendor — pricing and labeling before every show — from hours of work into minutes. IMPORT YOUR WHOLE COLLECTION Bring in your entire inventory as a CSV from TCGplayer, Shiny, or Collectr — or any generic spreadsheet. Open files straight from Mail, Files, or Drive with "Open in ShadowTag." Your file's prices are the prices: ShadowTag never second-guesses you with internet lookups. PRICE IT YOUR WAY The visual price ladder splits your inventory into bands you control — under $10, under $100, and up — each with its own rule: clean dollars, charm 9s, odd dollars with a cap, exact price, or your own steps. Drag the boundaries, watch real cards from your collection preview their new labels, and reprice everything in one tap. DESIGN YOUR LABEL Your logo, your QR code, your words. Upload a logo and size it to taste, point the QR at your shop or socials, and preview the exact label the printer will produce — what you see is what prints. THE STICKER MEMORY ShadowTag remembers every label you print. Re-import a newer file next week and it flags exactly which cards moved past your reprint threshold — NEW and CHANGED — so you print the 23 labels that need it, not all 400. You set the threshold: reprint often, or only on big moves. PRINT IN BATCHES, ON YOUR TERMS Select with a tap or a two-finger sweep, see the time estimate before you commit, and print the whole batch — with Pause whenever the booth gets busy and Resume when it clears, even after closing the app. WORKS AT THE SHOW Everything runs on your phone, offline. Bad venue wifi can't touch your prices, your labels, or your printing. PRINTERS Works with Nelko P21 and NIIMBOT D11/D110 Bluetooth label printers. (A supported label printer is required for printing; importing, pricing, and designing work without one.) PRIVATE BY DESIGN No accounts. No tracking. No data collection. Your inventory never leaves your phone. Built by a card vendor, for card vendors. Update 330 labels in about 30 minutes — and get your show-prep evenings back.
