# Unreal Chemist vs Periodic Table Memorization

The clearest difference is ratings volume: Unreal Chemist at 68 against Periodic Table Memorization's 5. Unreal Chemist also leads on iOS requirement (11.0 vs 17.0). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Unreal Chemist sells 1 one-off in-app purchase and Periodic Table Memorization sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
