# EE ToolKit vs Mechanical FE Prep

The clearest difference is update cadence: Mechanical FE Prep at every 5 days against EE ToolKit's every 3 months. Mechanical FE Prep also leads on rating (5.0 vs 4.7) and review sentiment (100% vs 90%). EE ToolKit's advantage is ratings volume (1.4K vs 2). 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 Mechanical FE Prep sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Mechanical FE Prep holds the better App Store score, 5.0 against 4.7. 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 100% of Mechanical FE Prep's.

EE ToolKit ships an update every 3 months, Mechanical FE Prep every 5 days. The most recent releases landed on October 12, 2026 and September 29, 2026 respectively.
