Spool Tracker vs Filament Depot

Know exactly how much filament you have — and what every print costs. Add your whole shelf in minutes, then stop guessing for good. SpoolVault is a filament inventory built for 3D printing. Weigh a spool, log a print, and you always know what's left, what it cost, and which printer or shelf it's sitting on. ADD YOUR WHOLE SHELF IN MINUTES Pick a brand and a material, tap every color you own, set how many of each, and save them all in one go. Then do the same for your next brand. Brands, materials and colors come preloaded for Bambu Lab, eSUN, Polymaker, Prusament, Hatchbox, Overture, Inland, Sunlu, Elegoo and BIQU. KNOW WHAT'S LEFT ON EVERY SPOOL Put a spool on any kitchen scale and enter the number. SpoolVault subtracts the empty spool's weight and tells you the filament remaining. Brand-specific spool weights are already built in, so it's a real figure, not a guess. KNOW WHAT EVERY PRINT COSTS Enter what you paid for a spool and SpoolVault works out the material cost of every print from the grams used — so you finally know what the thing you just made actually cost. KNOW WHERE EVERY SPOOL IS Assign spools to a printer, an AMS or multi-material slot, and a storage location — drybox, shelf, cupboard, wherever they really live. Then find any color in seconds. GROUP A BUILD INTO A PROJECT Multi-plate print? Group the plates under one named project and see total filament used, estimated material cost, and a full breakdown of every spool that went into it.

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.
