Verdict

The call

The clearest difference is ads: 3D Model Viewer at none against Cardabase's shown. 3D Model Viewer also leads on device support (4 vs 1) and iOS requirement (15.6 vs 17.0). Cardabase's advantage is update cadence (daily vs weekly). On price and in-app purchases there is nothing between them.
