# Karnaugh Map Advanced vs Circuit Simulator

The clearest difference is in-app purchases: Karnaugh Map Advanced at none against Circuit Simulator's 8. Circuit Simulator's advantage is update cadence (every 6 weeks vs every 9 months) and ratings volume (87 vs 4). On price, rating, review sentiment and ads there is nothing between them.

On the App Store both sit at effectively the same score — 4.8 for Karnaugh Map Advanced against 4.7 for Circuit Simulator.
