# EE ToolKit vs ID Resistors

The clearest difference is in-app purchases: ID Resistors at none against EE ToolKit's 1. ID Resistors also leads on review sentiment (100% vs 90%). EE ToolKit's advantage is ratings volume (1.4K vs 32) and iOS requirement (12.0 vs 14.0). On price, rating, update cadence and ads there is nothing between them.

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

ID Resistors holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: EE ToolKit has 1.4K ratings behind it against 32, 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 100% of ID Resistors's.

EE ToolKit ships an update every 3 months, ID Resistors every 2 months. Both last shipped on October 24, 2026.
