# EE ToolKit vs Thevenin

The clearest difference is rating: EE ToolKit at 4.7 against Thevenin's 4.2. EE ToolKit also leads on ratings volume (1.4K vs 10) and device support (3 vs 1). Thevenin's advantage is update cadence (every 3 days vs every 3 months) and review sentiment (100% vs 90%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. EE ToolKit sells 1 one-off in-app purchase and Thevenin sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

EE ToolKit holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: EE ToolKit has 1.4K ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 90% of EE ToolKit's written reviews are positive against 100% of Thevenin's, so the app with the better star average is not the one people write more warmly about.

EE ToolKit ships an update every 3 months, Thevenin every 3 days. The most recent releases landed on October 15, 2026 and October 17, 2026 respectively.
