# iCircuit vs EE ToolKit

The clearest difference is price: EE ToolKit at Free against iCircuit's $12.99. EE ToolKit also leads on rating (4.7 vs 3.8) and review sentiment (90% vs 61%). iCircuit's advantage is update cadence (every 4 weeks vs every 3 months). On ads, in-app purchases, device support and iOS requirement there is nothing between them.

EE ToolKit is free to download; iCircuit costs $12.99 up front. iCircuit sells 2 in-app purchases, starting at $1.99 per month and EE ToolKit sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

EE ToolKit holds the better App Store score, 4.7 against 3.8. That said, the two scores are not equally well evidenced: EE ToolKit has 1.4K ratings behind it against 135, so its average is the more settled of the two. Written reviews point the same way: 61% of iCircuit's written reviews are positive against 90% of EE ToolKit's.

iCircuit ships an update every 4 weeks, EE ToolKit every 3 months. Both last shipped on October 15, 2026.
