Verdict

The call

The clearest difference is in-app purchases: 3D Filament Inventory at none against Spool Master's 2. 3D Filament Inventory also leads on ads (none vs shown). Spool Master's advantage is update cadence (every 3 days vs every 2 weeks) and iOS requirement (15.0 vs 18.1). On price and device support there is nothing between them.
