Verdict
The clearest difference is price: Cadmio Viewer at Free against Valence 3D's $19.99. Cadmio Viewer also leads on rating (5.0 vs 4.2) and iOS requirement (14.0 vs 18.0). Valence 3D's advantage is update cadence (weekly vs every 6 weeks) and ratings volume (121 vs 3). On ads, in-app purchases, monetization model and device support there is nothing between them.
