Verdict
The clearest difference is in-app purchases: OBE Engineering System at none against MolecuLens's 2. OBE Engineering System also leads on iOS requirement (12.0 vs 15.1). MolecuLens's advantage is update cadence (monthly vs every 9 months). On price, ads and device support there is nothing between them.
