# Bärhausen vs PID Controller Simulation

The clearest difference is price: Bärhausen at Free against PID Controller Simulation's $3.99. PID Controller Simulation's advantage is update cadence (every 3 months vs every 22 months) and iOS requirement (13.0 vs 15.0). On ads, in-app purchases and device support there is nothing between them.

Bärhausen is free to download; PID Controller Simulation costs $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Bärhausen ships an update every 22 months, PID Controller Simulation every 3 months. The most recent releases landed on September 9, 2026 and September 23, 2026 respectively.
