# Quantum Mechanics vs Bernstein

The clearest difference is iOS requirement: Quantum Mechanics at 9.0 against Bernstein's 15.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
