SpoolSense vs SpoolTagWriter

SpoolSense turns your iPhone into an NFC reader and writer for 3D-printing filament spools. Tap a tagged spool and SpoolSense instantly shows you what it is: material, brand, color, nozzle and bed temperatures, filament diameter, density, and how much is left on the roll. No typing, no guessing which spool is which. READ AND WRITE FIVE TAG FORMATS - OpenPrintTag (ISO 15693, ICODE SLIX2) - OpenSpool (ISO 14443A, NTAG215/216) - TigerTag (ISO 14443A, NTAG213/215/216) - OpenTag3D (ISO 14443A, NTAG215/216) - NFC+ - register any blank tag's UID against your inventory Write a blank tag from scratch, or read an existing tag and edit it. SpoolSense verifies every write by reading the tag back. WORKS ON ITS OWN Reading and writing tags needs nothing but your iPhone and a tag. No account, no subscription, no server, no cloud. SpoolSense collects no data whatsoever. OPTIONAL: SPOOLMAN INVENTORY Point SpoolSense at a self-hosted Spoolman server and your whole filament inventory syncs to your phone. Browse every spool, search by material or vendor, see remaining weight at a glance, and get a low-spool warning at a threshold you choose. Scans update Spoolman automatically, and used filament is deducted for you. OPTIONAL: SEND TO YOUR PRINTER Scan a spool and push it straight to the printer you just loaded it into: - Snapmaker U1 - assign the spool to a channel over your local network - Klipper with AFC / Happy Hare / a toolchanger - route through SpoolSense middleware for tool assignment and automatic deductions - Plain Klipper - scans keep Spoolman up to date Pick any combination, or none. A phone can roam between printers. PRIVACY Everything lives on your own devices and your own servers. SpoolSense has no analytics, no tracking, no accounts, and no ads, and it never sends your data anywhere. REQUIREMENTS NFC scanning and writing require a physical iPhone (iPhone 7 or later). Spoolman and printer integration are optional and require software you run yourself on your own network.

SpoolTagWriter lets you read and write NFC tags for 3D printer filament spools from your iPhone. Use it to scan existing spool tags, view the stored filament data, and create new tags with either preset profiles or custom settings. The app is designed to make spool setup faster, cleaner, and easier to manage without digging through raw tag values by hand. Features: - Scan compatible NFC filament tags - View parsed spool data including brand, material, color, diameter, weight, and extruder temperature range - Inspect raw NFC page data for supported tags - Write tags using preset filament profiles - Browse presets by brand, material type, and color - Create custom spool settings for your own filament - Choose custom colors visually or by entering a hex value - Write spool data in a streamlined iPhone-first workflow SpoolTagWriter is built for makers who want a simple way to manage filament tag data and prepare spools for supported 3D printing workflows.
