# Circuit Simulator vs Electro Sim

The clearest difference is review sentiment: Electro Sim at 100% against Circuit Simulator's 73%. Circuit Simulator's advantage is iOS requirement (15.3 vs 17.6). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Circuit Simulator sells 8 in-app purchases, starting at $0.99 per month and Electro Sim sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
