Every 3D printer owner knows the feeling: a long print ahead, a half-used spool in hand, and no idea if it will make it. Ply answers that question — to the gram. FROM SLICER TO SHELF Open a sliced file from Bambu Studio, PrusaSlicer, OrcaSlicer or Cura and Ply reads the slicer's own estimate, picks the matching spool, and logs the print in one tap. No typing, no math. THE SPOOL WALL Your whole shelf at a glance. Every spool drawn as it really is: filament wound around a hub, thinning as you print. Grouped by material, ordered by colour, with low-stock spools flagged before they surprise you. WEIGH. DONE. Put the spool on a kitchen scale, type one number, and Ply works out exactly how much filament is left — grams and meters. Or log prints as you go; the ledger keeps itself honest. ENOUGH FOR THIS PRINT? Type what your slicer estimates. Ply instantly shows which spools can cover it — and suggests finishing the almost-empty ones first. NFC SPOOL TAGS Stick a cheap NTAG tag on a spool, write it once, and identify any spool with a tap. Uses the open OpenSpool format — no vendor lock-in. Prefer paper? Print a QR label instead and scan it with your Camera. REMEMBER WHAT WORKED Rate a filament, note the temperatures that printed clean, and keep those notes on every spool of it — including the next one you buy. DRYING, HANDLED Log drying cycles, run a drying timer with a Live Activity on your Lock Screen, and get a nudge when a spool is likely damp again. BUILT INTO iOS Search any spool straight from Spotlight and tap to open it. Ask Siri — or run a Shortcut — to check what filament you have left or log a print, hands-free. Add the Home Screen widget for total stock at a glance. YOUR DATA IS YOURS Everything lives on your device and in your own iCloud. No accounts, no tracking, no ads. Import your existing spreadsheet (or Spoolman export) in one tap; export CSV any time. FREE forever for up to 15 spools — including NFC, drying, alerts, and the widget. One affordable Lifetime Pro purchase unlocks unlimited spools, iCloud sync across devices, full analytics, and CSV export. No subscription. Ever.

Verdict
The clearest difference is in-app purchases: SpoolyTracker at none against Ply's 1. SpoolyTracker also leads on iOS requirement (15.1 vs 26.0). Ply's advantage is update cadence (every 5 days vs every 9 days). On price, ads and device support there is nothing between them.
