# Chemguy vs Unreal Chemist

The clearest difference is rating: Chemguy at 5.0 against Unreal Chemist's 4.5. Chemguy also leads on ads (none vs shown) and review sentiment (100% vs 73%). Unreal Chemist's advantage is update cadence (every 2 weeks vs every 41 months) and ratings volume (68 vs 4). On price, in-app purchases and device support there is nothing between them.

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

Chemguy 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 4, so its average is the more settled of the two. Written reviews point the same way: 100% of Chemguy's written reviews are positive against 73% of Unreal Chemist's.

Chemguy ships an update every 41 months, Unreal Chemist every 2 weeks. Both last shipped on November 3, 2026.
