# Circuit Simulator vs PLC Ladder Logic Simulator

The clearest difference is rating: Circuit Simulator at 4.7 against PLC Ladder Logic Simulator's 4.0. Circuit Simulator also leads on ratings volume (95 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Circuit Simulator sells 8 in-app purchases, starting at $0.99 per month and PLC Ladder Logic Simulator sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Circuit Simulator holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Circuit Simulator has 95 ratings behind it against 1, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on November 12, 2026 and November 11, 2026 respectively.
