Verdict
The clearest difference is in-app purchases: PSC Trials at none against Molecular Models's 1. PSC Trials also leads on iOS requirement (13.0 vs 15.6). Molecular Models's advantage is ads (none vs shown) and update cadence (every 9 days vs every 3 weeks). On price and device support there is nothing between them.
