# Circuitry vs Electro Sim

The clearest difference is review sentiment: Electro Sim at 100% against Circuitry's 51%. Circuitry's advantage is in-app purchases (none vs 2) and iOS requirement (12.0 vs 17.6). On price, ads and device support there is nothing between them.

Both are free to download. Electro Sim sells 2 one-off in-app purchases. Circuitry asks for nothing beyond the download.
