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. — ASK YOUR INVENTORY ANYTHING — Type a question — like "how many grams of red PLA do I have?" — and get an instant answer instead of adding it up yourself. Powered entirely by on-device Apple Intelligence: nothing leaves your device, no internet required. No Apple Intelligence? Search still works as before. — KNOW WHAT YOU HAVE — Browse your collection filtered by state, brand, type, color family, or location, with live counts on each filter. Sort by grams remaining to spot low spools at a glance. Each spool shows its true color and hex code, plus its weight, state (New → In Use → Low → Empty → Retired) with a colored stripe, event history, and photos. — SMART INTAKE & AUTO-FILL — Skip tedious data entry. Paste text from a product page or receipt—or on iPhone and iPad, use your camera to scan text off box and bag labels. On compatible devices, on-device Apple Intelligence extracts the brand, material, color, and net weight instantly. — SCAN TO FIND. SCAN TO MOVE. — Print a QR code for any spool or location and scan it with your iPhone, iPad, or Mac camera, or use your iPhone to write and scan custom NFC tags at your workbench. A quick tap or scan instantly identifies what's loaded and where it is. To move a spool, tap Move and scan the destination — your preferred method (NFC, QR, or a list) opens instantly. — 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, or connect a Bluetooth scale to weigh a spool and get its remaining filament instantly — set the empty weight once and every future weigh-in subtracts it automatically. Loading filament starts with your refills, sortable by brand, color, or amount left. Attach photos from your camera, photo library, or Files. Track purchase price, source URL, and currency per spool. — SIRI & SHORTCUTS — Ask Siri where a spool is, check how much filament you have left, or log print usage hands-free — or use them in your own Shortcuts. — BUILT-IN FILAMENT REFERENCE — Look up print temperatures, drying recommendations, density, and resistance ratings for ~30 filament types — from PLA and PETG to specialty materials like PA6-CF, BVOH, and ASA. Tap any entry to filter your spools by that type. — ICLOUD SYNC — Your inventory syncs silently across all your devices via CloudKit and works fully offline. Sync diagnostics and a cache reset are in Settings. — BACKUP & RESTORE — Export a complete snapshot — spools, filament, locations, history, photos, and reference data — as an archive or plain JSON. Restore any time via a safe path that never risks data loss in iCloud. — CSV EXPORT & IMPORT — Export your full inventory as a 30-column CSV for Numbers, Excel, or any spreadsheet. Import it back to bulk-update brand, type, color, location, purchase info, and more, matched by Spool ID. — LIGHT & DARK MODE, ACCESSIBILITY — Follows your device's Light or Dark Mode, or pick one in Settings. Every screen supports VoiceOver and Dynamic Type. — SEAMLESS MAC COMPANION — Runs natively on Mac with the same data, sync, and features as iPhone and iPad, including search from macOS Spotlight. The Mac also supports the TD-1 filament tester: capture transmission-distance and hex color readings over USB, synced to all your devices. No subscriptions. No account required beyond iCloud — your data stays in your own private iCloud database. Optional tips in Settings support development, and a one-time Supporter purchase adds a thank-you badge — never required.

Verdict
The clearest difference is rating: Filament at 4.0 against Rainbow Fish Pencil Tracker's 3.1. Filament also leads on monetization model (free vs free with in-app purchases). Rainbow Fish Pencil Tracker's advantage is ratings volume (7 vs 1) and iOS requirement (9.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Rainbow Fish Pencil Tracker sells 2 one-off in-app purchases and Filament sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Filament holds the better App Store score, 4.0 against 3.1. That said, the two scores are not equally well evidenced: Rainbow Fish Pencil Tracker has 7 ratings behind it against 1, so its average is the more settled of the two.
