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.

ReceptionRating · Positive reviews · Number of ratings

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.
