# Organic Nomenclature vs WebMO Molecule Editor

The clearest difference is rating: Organic Nomenclature at 4.7 against WebMO Molecule Editor's 4.0. Organic Nomenclature also leads on review sentiment (88% vs 60%) and ratings volume (660 vs 40). WebMO Molecule Editor's advantage is update cadence (every 3 months vs every 21 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Organic Nomenclature sells 2 one-off in-app purchases and WebMO Molecule Editor sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Organic Nomenclature holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Organic Nomenclature has 660 ratings behind it against 40, so its average is the more settled of the two. Written reviews point the same way: 88% of Organic Nomenclature's written reviews are positive against 60% of WebMO Molecule Editor's.
