Filament-Tracker

Take control of your 3D printer filament collection. Filament Tracker is a native app for iPhone, iPad, and Mac that gives every spool a unique ID, a home, and a complete history — from purchase to retirement. Manage your inventory seamlessly on your mobile devices, leveraging quick QR scanning on both iPhone and iPad, alongside powerful hardware NFC tag scanning on your iPhone. — KNOW WHAT YOU HAVE — Browse your entire collection filtered by state, brand, type, color family, or location. Sort by grams remaining to spot low spools at a glance. Every spool tracks its weight, state (New → In Use → Low → Empty → Retired), event history, and photos. — SMART INTAKE & AUTO-FILL — Skip tedious data entry when adding new inventory. Paste text straight from a product page or receipt—or on iPhone and iPad, use your device camera to scan text directly off physical box and bag labels. For compatible devices, on-device Apple Intelligence automatically parses the text to extract the spool's brand, material, color, and net weight instantly. — SCAN TO FIND. SCAN TO MOVE. — Print a QR code for any spool or location, or use your iPhone to write and scan custom NFC tags right at your workbench. A quick tap of an NFC tag with your iPhone, or a swift camera scan of a QR code on either iPhone or iPad, instantly identifies exactly what's loaded and where it is. Move a spool to a new location in two quick scans. — LOCATIONS THAT FIT YOUR SETUP — Organize your collection by dry box, AMS unit, shelf, printer, or any location you define. Locations marked as Connected to Printer automatically count loaded spools as In Use. — TRACK EVERY GRAM — Log print sessions to keep grams-remaining accurate. Attach photos from your camera, photo library, or Files to any spool or filament record. Track purchase price and source URL per spool, with per-spool currency overrides for international purchases. — BUILT-IN FILAMENT REFERENCE — Look up print temperatures, drying recommendations, density, and resistance ratings for ~30 common filament types — from PLA and PETG to specialty materials like PA6-CF, BVOH, and ASA. Tap any reference entry to instantly filter your spools by that type. — ICLOUD SYNC — Your inventory syncs silently across all your devices via CloudKit. Works fully offline; changes sync automatically when connectivity returns. Full sync diagnostics and a local cache reset are available right in Settings. — BACKUP & RESTORE — Export a complete snapshot — spools, filament, locations, event history, photos, and reference data. Restore at any time using a safe path that never risks accidental data loss to iCloud. — CSV EXPORT & IMPORT — Export your full inventory as a 28-column CSV for Numbers, Excel, or any spreadsheet app. Import it back to bulk-update brand, type, color, location, purchase info, and more — matched by Spool ID, with missing reference entries created automatically. — SEAMLESS MAC COMPANION — The app runs natively on Mac with the same data, sync, and features as on iPhone and iPad. The Mac version additionally supports the TD-1 filament tester — capture optical transmission-distance and hex color readings directly via USB and sync them back to your iOS devices automatically. No subscriptions. No account required beyond iCloud. Your data stays in your own private iCloud database.
