# Sclera vs PID Controller Simulation

The clearest difference is price: Sclera at Free against PID Controller Simulation's $3.99. Sclera also leads on rating (3.4 vs 3.0) and update cadence (fortnightly vs every 3 months). PID Controller Simulation's advantage is iOS requirement (13.0 vs 15.6). On ads, in-app purchases and device support there is nothing between them.

Sclera is free to download; PID Controller Simulation costs $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Sclera holds the better App Store score, 3.4 against 3.0. Both are backed by a comparable volume of ratings — 9 and 2 respectively.

Sclera ships an update fortnightly, PID Controller Simulation every 3 months. The most recent releases landed on October 10, 2026 and October 9, 2026 respectively.
