# Bernstein vs Quantum

The clearest difference is in-app purchases: Bernstein at none against Quantum's 6. Bernstein also leads on iOS requirement (15.0 vs 26.0). On price, ads and device support there is nothing between them.

Both are free to download. Quantum sells 3 one-off in-app purchases. Bernstein asks for nothing beyond the download.
