# EE ToolKit vs Circuitry

The clearest difference is rating: EE ToolKit at 4.7 against Circuitry's 3.9. EE ToolKit also leads on review sentiment (90% vs 51%) and ratings volume (1.4K vs 155). Circuitry's advantage is in-app purchases (none vs 1). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. EE ToolKit sells 1 one-off in-app purchase. Circuitry asks for nothing beyond the download.

EE ToolKit holds the better App Store score, 4.7 against 3.9. That said, the two scores are not equally well evidenced: EE ToolKit has 1.4K ratings behind it against 155, so its average is the more settled of the two. Written reviews point the same way: 90% of EE ToolKit's written reviews are positive against 51% of Circuitry's.

EE ToolKit ships an update every 3 months, Circuitry every 4 months. The most recent releases landed on October 1, 2026 and September 29, 2026 respectively.
