Your prices, on real stickers, from the phone in your pocket. ShadowTag turns your trading-card inventory into professional price labels—without rebuilding your collection or surrendering control of your prices. Import your file, choose your pricing rules, customize your label, and print an entire show from your iPhone. YOUR PRICES. YOUR RULES. • Your imported price is the price. ShadowTag does not second-guess it. • Pin any price so it stays exactly where you set it. • Build pricing bands for different value ranges. • Round to clean dollars, odd-dollar prices, even-dollar prices, or add your own bump. PRINT WITH CONFIDENCE • Select individual cards or print a full batch. • Quantities create the correct number of physical labels. • Pause and resume printing without losing your place. • Follow real sticker progress in the app and Dynamic Island. • Interrupted labels remain queued instead of being silently marked as printed. • Print through compatible Bluetooth thermal label printers. MAKE EVERY LABEL YOURS • Add the card name, your own text, logo, and QR code. • Preview the finished label before printing. • Keep a consistent, professional look across your entire booth. KNOW WHAT NEEDS PRINTING ShadowTag remembers your labels and separates new, changed, and previously printed cards, so you can update stale prices without reprinting everything.
