Filament Depot: 3D Spool Log

New in 1.0: track every spool you own as a colour ring, log usage in seconds, and follow price changes across vendors. One-time $1.99 Pro unlock, no subscription.

Filament Depot is a clean, Apple-Health–inspired iOS app for makers who print a lot. Track every filament spool you own as a colour ring with remaining filament at a glance — log usage as you print, follow price changes across vendors, and never run out mid-job.

THE WALL — VISUAL INVENTORY Every spool gets its own concentric colour ring. The colour is the filament; the ring's thickness is what's left. Search by name or brand, filter by material, sort by lowest-first to instantly spot what needs reordering.

LOG USAGE WITHOUT FRICTION Tap a spool, enter grams used, see exactly what's left after this print. Quick-pick buttons for 10, 25, 50, 100, 200g. Optional confirmation step you can switch off once you trust the flow.

PRICE-AWARE TOP-UPS Every purchase is logged as a lot — its own date, price, and vendor. The Purchase History card shows your last paid price, your weighted average per kilogram, and the % change vs your previous lot. A new top-up that's more than 0.5% off the last price triggers an alert; above 10%, it warns you to double-check the vendor before saving.

THOUGHTFUL TOUCHES • Concentric "activity rings" summary card — filament on hand, dry & ready, active spools • 7-day usage sparkline per spool • Light, dark, and auto themes with five accent swatches • Localised in English, Spanish, French, German, Italian, Japanese, Simplified Chinese, and Turkish

FREE TIER Track up to 2 spools with the full design — no ads, no time limit, no upsell modals shoved in your face.

PRO · $1.99 ONE-TIME UNLOCK • Unlimited spools • Full price history per spool with weighted-average and trend tracking • Add custom materials beyond the built-in PLA, PLA+, PETG, ABS, TPU 95A • One-time purchase, no subscription, no auto-renewal, no recurring fees

PRIVACY-FIRST Filament Depot collects nothing. No analytics, no ads, no tracking SDKs, no servers. Your inventory lives on your device and is backed up only via your encrypted Apple device backup if you have one enabled.
