The clearest difference is review sentiment: iMolview Lite at 100% against MoleculeSketch iP's 50%. iMolview Lite also leads on in-app purchases (none vs 1) and device support (3 vs 1). MoleculeSketch iP's advantage is rating (4.5 vs 4.0) and update cadence (every 2 months vs every 9 months). On price, ratings volume, ads and iOS requirement there is nothing between them.
