Chemistry experiments on your smartphones. You can Mix chemicals to see how they react, Burn salts to colorful flames and Heat elements to see what colors it emits There are 150 plus chemicals available to experiment with and more than 750 unique experiment simulations. Key Highlights - Adjusting the concentration and quantity of the reactants. - Regulate the temperature of the reaction. - Modify temperatures in precipitation reactions and see the effect of temperatures on solubility. - Slow down / Fast forward time. - Check the PH and PH change in a reaction, using Indicators. - Ignite flammable gases formed during reaction. Disclaimer Some reactions you will be doing in Unreal Chemist are extremely dangerous and may cause serious injury if conducted in real word. Even though most of the reactions are accurate to the real world, some reactions may be theoretical since physical verification of some reactions are not completed as of now.

Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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.
