# Engine Sim vs Tuning Simulator

The clearest difference is ads: Tuning Simulator at none against Engine Sim's shown. Tuning Simulator also leads on monetization model (free vs free with in-app purchases) and rating (4.8 vs 4.6). Engine Sim's advantage is ratings volume (1.1K vs 8) and review sentiment (86% vs 67%). On price, update cadence, in-app purchases and chart position there is nothing between them.

Both are free to download. Engine Sim sells 15 one-off in-app purchases 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, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Engine Sim has 1.1K ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 86% of Engine Sim's written reviews are positive against 67% of Tuning Simulator's, so the app with the better star average is not the one people write more warmly about.

Engine Sim ships an update every 3 days, Tuning Simulator every 2 days. The most recent releases landed on October 31, 2026 and November 1, 2026 respectively.
