# PrepFE vs Mechanical Components

The clearest difference is rating: Mechanical Components at 3.0 against PrepFE's 2.0. PrepFE's advantage is update cadence (every 2 months vs every 7 months) and ratings volume (57 vs 2). 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 Components sells 4 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Mechanical Components holds the better App Store score, 3.0 against 2.0. That said, the two scores are not equally well evidenced: PrepFE has 57 ratings behind it against 2, so its average is the more settled of the two.

PrepFE ships an update every 2 months, Mechanical Components every 7 months. The most recent releases landed on October 8, 2026 and October 2, 2026 respectively.
