# EE ToolKit vs Engineering & FE Prep

The clearest difference is review sentiment: EE ToolKit at 90% against Engineering & FE Prep's 62%. EE ToolKit also leads on rating (4.7 vs 4.5) and ratings volume (1.4K vs 171). Engineering & FE Prep's advantage is update cadence (every 2 weeks vs every 3 months). 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 Engineering & FE Prep sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

EE ToolKit holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: EE ToolKit has 1.4K ratings behind it against 171, 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 62% of Engineering & FE Prep's.

EE ToolKit ships an update every 3 months, Engineering & FE Prep every 2 weeks. The most recent releases landed on September 23, 2026 and September 15, 2026 respectively.
