Verdict
The clearest difference is price: Bar at Free against 3D CAD & Mesh Viewer's $0.99. Bar also leads on iOS requirement (13.0 vs 26.0). 3D CAD & Mesh Viewer's advantage is ads (none vs shown) and update cadence (every 2 weeks vs every 20 months). On in-app purchases and device support there is nothing between them.
