# PID Controller Simulation vs E

The clearest difference is review sentiment: E at 100% against PID Controller Simulation's 33%. E also leads on update cadence (every 5 weeks vs every 3 months). PID Controller Simulation's advantage is price ($3.99 vs $6.99) and iOS requirement (13.0 vs 26.0). On ads, in-app purchases, monetization model and device support there is nothing between them.

PID Controller Simulation costs $3.99 and E $6.99 up front. Neither carries in-app purchases, so what you see is what you pay.

PID Controller Simulation ships an update every 3 months, E every 5 weeks. The most recent releases landed on October 24, 2026 and October 22, 2026 respectively.
