Tag My Spool – NFC Filament for iOS: Limited-Time App Store Discount

Tag My Spool – NFC Filament for iOS is currently available at a limited-time discount, dropping from $4.99 to $3.99 — a 20% saving of $1.00. This productivity app is a practical tool for 3D printing enthusiasts who use NFC or RFID tags to manage filament spools. It lets you read, write, and organize spool data such as material type, color, brand, and temperature settings, supporting protocols like ACE Pro, OpenSpool, and OpenPrintTag. The app also integrates with the Open Filament Database for quick profile imports. While the discount is modest, it brings the price in line with similar filament management utilities, which often lack the same breadth of protocol support and customization options. For hobbyists or makers with a growing filament collection, Tag My Spool offers a streamlined way to keep every spool labeled and trackable. The current deal is a fair entry point, though the feature set justifies the original price for dedicated users. If you regularly switch filaments or want to avoid guesswork with your 3D printer, this is a solid investment at the reduced price.
