# PLC AI vs Electro Sim

The clearest difference is review sentiment: Electro Sim at 100% against PLC AI's 29%. PLC AI's advantage is rating (4.5 vs 4.0) and update cadence (every 3 weeks vs every 4 months). On price, ads, in-app purchases and monetization model 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 Electro Sim sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

PLC AI holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: PLC AI has 84 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 29% of PLC AI's written reviews are positive against 100% of Electro Sim's, so the app with the better star average is not the one people write more warmly about.

PLC AI ships an update every 3 weeks, Electro Sim every 4 months. The most recent releases landed on October 24, 2026 and October 22, 2026 respectively.
