# iCircuit vs Circuit Simulator

The clearest difference is price: Circuit Simulator at Free against iCircuit's $12.99. Circuit Simulator also leads on rating (4.7 vs 3.8) and review sentiment (77% vs 61%). iCircuit's advantage is iOS requirement (13.0 vs 15.3). On ratings volume, update cadence, ads and in-app purchases there is nothing between them.

Circuit Simulator is free to download; iCircuit costs $12.99 up front. iCircuit sells 2 in-app purchases, starting at $1.99 per month and Circuit Simulator sells 8 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Circuit Simulator holds the better App Store score, 4.7 against 3.8. Both are backed by a comparable volume of ratings — 142 and 93 respectively. Written reviews point the same way: 61% of iCircuit's written reviews are positive against 77% of Circuit Simulator's.

iCircuit ships an update every 4 weeks, Circuit Simulator every 6 weeks. The most recent releases landed on October 29, 2026 and October 27, 2026 respectively.
