# Chemist Calc vs Unreal Chemist

The clearest difference is rating: Chemist Calc at 5.0 against Unreal Chemist's 4.5. Chemist Calc also leads on ads (none vs shown) and monetization model (free vs free with in-app purchases). Unreal Chemist's advantage is update cadence (every 2 weeks vs every 9 months) and ratings volume (68 vs 1). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Chemist Calc 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.

Chemist Calc 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 1, so its average is the more settled of the two.

Chemist Calc ships an update every 9 months, Unreal Chemist every 2 weeks. The most recent releases landed on October 16, 2026 and October 20, 2026 respectively.
