# EE ToolKit vs Thermo Jesus

The clearest difference is rating: EE ToolKit at 4.7 against Thermo Jesus's 4.0. EE ToolKit also leads on ratings volume (1.4K vs 4). Thermo Jesus's advantage is update cadence (every 3 weeks 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 Thermo Jesus sells 3 in-app purchases, starting at $1.99 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 4.0. That said, the two scores are not equally well evidenced: EE ToolKit has 1.4K ratings behind it against 4, 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 Thermo Jesus'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, Thermo Jesus every 3 weeks. Both last shipped on October 24, 2026.
