# Unreal Chemist vs Molecular Models

The clearest difference is ads: Molecular Models at none against Unreal Chemist's shown. Molecular Models also leads on review sentiment (100% vs 73%). Unreal Chemist's advantage is iOS requirement (11.0 vs 15.6). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Unreal Chemist sells 1 one-off in-app purchase and Molecular Models sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Unreal Chemist ships an update every 2 weeks, Molecular Models every 9 days. The most recent releases landed on October 20, 2026 and October 28, 2026 respectively.
