# Engine Simulator vs Tuning Simulator

The clearest difference is rating: Tuning Simulator at 5.0 against Engine Simulator's 4.3. Tuning Simulator also leads on update cadence (every 3 days vs every 3 weeks) and iOS requirement (15.0 vs 18.6). Engine Simulator's advantage is ratings volume (127 vs 5). On price, ads, in-app purchases and chart position there is nothing between them.

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

Tuning Simulator holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Engine Simulator has 127 ratings behind it against 5, so its average is the more settled of the two.

Engine Simulator ships an update every 3 weeks, Tuning Simulator every 3 days. The most recent releases landed on October 18, 2026 and October 22, 2026 respectively.
