# EE ToolKit vs Circuit

The clearest difference is review sentiment: EE ToolKit at 90% against Circuit's 0%. EE ToolKit also leads on rating (4.7 vs 1.0) and ads (none vs shown). Circuit's advantage is in-app purchases (none vs 1) and update cadence (every 5 weeks vs every 3 months). On price and device support there is nothing between them.

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

EE ToolKit holds the better App Store score, 4.7 against 1.0. That said, the two scores are not equally well evidenced: EE ToolKit has 1.4K ratings behind it against 2, 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 0% of Circuit's.

EE ToolKit ships an update every 3 months, Circuit every 5 weeks. Both last shipped on October 12, 2026.
