# Mechanic vs Engine Simulator

The clearest difference is rating: Mechanic at 4.7 against Engine Simulator's 4.3. Mechanic also leads on update cadence (every 11 days vs every 2 months) and ratings volume (679 vs 98). Engine Simulator's advantage is review sentiment (81% vs 60%) and chart position (#48 vs unranked). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Mechanic sells 31 one-off in-app purchases and Engine Simulator sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Mechanic holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Mechanic has 679 ratings behind it against 98, so its average is the more settled of the two. Written reviews complicate that: 60% of Mechanic's written reviews are positive against 81% of Engine Simulator's, so the app with the better star average is not the one people write more warmly about.

Mechanic ships an update every 11 days, Engine Simulator every 2 months. The most recent releases landed on October 13, 2026 and October 10, 2026 respectively.
