Verdict
The clearest difference is rating: Mechanical FE Prep at 5.0 against PrepFE's 4.2. Mechanical FE Prep also leads on update cadence (every 5 days vs monthly) and review sentiment (100% vs 75%). PrepFE's advantage is ratings volume (22 vs 3). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. PrepFE sells 6 one-off in-app purchases 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 4.2. That said, the two scores are not equally well evidenced: PrepFE has 22 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 75% of PrepFE's written reviews are positive against 100% of Mechanical FE Prep's.
PrepFE ships an update monthly, Mechanical FE Prep every 5 days. Both last shipped on October 24, 2026.
