# Lambda Tuner vs PID Controller Simulation

The clearest difference is update cadence: PID Controller Simulation at every 3 months against Lambda Tuner's every 19 months. PID Controller Simulation also leads on iOS requirement (13.0 vs 16.6). Lambda Tuner's advantage is rating (3.3 vs 3.0). On price, ratings volume, ads and in-app purchases there is nothing between them.

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

Lambda Tuner holds the better App Store score, 3.3 against 3.0. Both are backed by a comparable volume of ratings — 3 and 2 respectively.

Lambda Tuner ships an update every 19 months, PID Controller Simulation every 3 months. The most recent releases landed on July 5, 2026 and September 23, 2026 respectively.
