# Tool Box vs PID Controller Simulation

The clearest difference is rating: Tool Box at 3.9 against PID Controller Simulation's 3.0. Tool Box also leads on price ($0.99 vs $3.99) and ratings volume (16 vs 2). On review sentiment, ads, in-app purchases and monetization model there is nothing between them.

Tool Box costs $0.99 and PID Controller Simulation $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Tool Box holds the better App Store score, 3.9 against 3.0. That said, the two scores are not equally well evidenced: Tool Box has 16 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 40% of Tool Box's written reviews are positive against 33% of PID Controller Simulation's.
