# SimpleColor vs PID Controller Simulation

The clearest difference is rating: SimpleColor at 5.0 against PID Controller Simulation's 3.0. SimpleColor also leads on price ($1.99 vs $3.99). PID Controller Simulation's advantage is update cadence (every 3 months vs every 20 months). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.

SimpleColor costs $1.99 and PID Controller Simulation $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.

SimpleColor holds the better App Store score, 5.0 against 3.0. Both are backed by a comparable volume of ratings — 1 and 2 respectively.

SimpleColor ships an update every 20 months, PID Controller Simulation every 3 months. The most recent releases landed on October 4, 2026 and October 9, 2026 respectively.
