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 rating: MolViewApp at 5.0 against Unreal Chemist's 4.5. MolViewApp also leads on in-app purchases (none vs 1) and ads (none vs shown). Unreal Chemist's advantage is ratings volume (68 vs 2) and iOS requirement (11.0 vs 15.0). On price and device support there is nothing between them.

Both are free to download. Unreal Chemist sells 1 one-off in-app purchase. MolViewApp asks for nothing beyond the download.
MolViewApp holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Unreal Chemist has 68 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 73% of Unreal Chemist's written reviews are positive against 100% of MolViewApp's.
Unreal Chemist ships an update every 2 weeks, MolViewApp every 2 days. The most recent releases landed on November 3, 2026 and November 5, 2026 respectively.
