# Chip Simulator vs PLC AI

The clearest difference is price: PLC AI at Free against Chip Simulator's $0.99. PLC AI also leads on rating (4.5 vs 1.0) and update cadence (every 3 weeks vs every 3 months). Chip Simulator's advantage is in-app purchases (none vs 16) and review sentiment (38% vs 29%). On ads and device support there is nothing between them.

PLC AI is free to download; Chip Simulator costs $0.99 up front. PLC AI sells 16 in-app purchases, starting at $4.99 per 7 days. Chip Simulator asks for nothing beyond the download.

PLC AI holds the better App Store score, 4.5 against 1.0. That said, the two scores are not equally well evidenced: PLC AI has 84 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 38% of Chip Simulator's written reviews are positive against 29% of PLC AI's, so the app with the better star average is not the one people write more warmly about.

Chip Simulator ships an update every 3 months, PLC AI every 3 weeks. The most recent releases landed on October 11, 2026 and October 24, 2026 respectively.
