# PLC AI vs Control Systems Engineering

The clearest difference is update cadence: PLC AI at every 3 weeks against Control Systems Engineering's every 3 months. PLC AI also leads on device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. PLC AI sells 16 in-app purchases, starting at $4.99 per 7 days and Control Systems Engineering sells 6 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

PLC AI ships an update every 3 weeks, Control Systems Engineering every 3 months. The most recent releases landed on September 30, 2026 and September 14, 2026 respectively.
