# O Level Physics Quiz vs Unreal Chemist

The clearest difference is rating: O Level Physics Quiz at 5.0 against Unreal Chemist's 4.5. Unreal Chemist's advantage is ratings volume (68 vs 3). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. O Level Physics Quiz sells 7 in-app purchases, starting at $4.99 per month and Unreal Chemist sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
