# EE ToolKit vs Simurelay

The clearest difference is rating: EE ToolKit at 4.7 against Simurelay's 3.9. EE ToolKit also leads on review sentiment (90% vs 52%) and ratings volume (1.4K vs 17). 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 Simurelay sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

EE ToolKit holds the better App Store score, 4.7 against 3.9. That said, the two scores are not equally well evidenced: EE ToolKit has 1.4K ratings behind it against 17, 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 52% of Simurelay's.

EE ToolKit ships an update every 3 months, Simurelay every 7 months. The most recent releases landed on September 23, 2026 and August 1, 2026 respectively.
