# iResistors vs EE ToolKit

The clearest difference is review sentiment: EE ToolKit at 90% against iResistors's 27%. EE ToolKit also leads on price (Free vs $0.99) and ratings volume (1.4K vs 1). iResistors's advantage is in-app purchases (none vs 1) and rating (5.0 vs 4.7). On ads there is nothing between them.

EE ToolKit is free to download; iResistors costs $0.99 up front. EE ToolKit sells 1 one-off in-app purchase. iResistors asks for nothing beyond the download.

iResistors holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: EE ToolKit has 1.4K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 27% of iResistors's written reviews are positive against 90% of EE ToolKit's, so the app with the better star average is not the one people write more warmly about.

iResistors ships an update every 10 months, EE ToolKit every 3 months. The most recent releases landed on September 30, 2026 and October 24, 2026 respectively.
