# PID Controller Simulation vs KP PumpCalc

The clearest difference is price: KP PumpCalc at Free against PID Controller Simulation's $3.99. PID Controller Simulation's advantage is in-app purchases (none vs 1) and device support (3 vs 1). On ads there is nothing between them.

KP PumpCalc is free to download; PID Controller Simulation costs $3.99 up front. KP PumpCalc sells 1 one-off in-app purchase. PID Controller Simulation asks for nothing beyond the download.
