Verdict
The clearest difference is in-app purchases: Chem Viewer at none against CycleChem's 1. Chem Viewer also leads on update cadence (every 4 days vs every 6 months) and iOS requirement (11.0 vs 16.6). CycleChem's advantage is ads (none vs shown). On price and device support there is nothing between them.
