# Grover's algorithm vs Quantum Computing

The clearest difference is in-app purchases: Grover's algorithm at none against Quantum Computing's 1. Grover's algorithm also leads on iOS requirement (15.0 vs 17.0). On price, ads and device support there is nothing between them.

Both are free to download. Quantum Computing sells 1 one-off in-app purchase. Grover's algorithm asks for nothing beyond the download.
