# Engine Simulator vs Engine Sim

The clearest difference is ads: Engine Simulator at none against Engine Sim's shown. Engine Simulator also leads on device support (3 vs 1). Engine Sim's advantage is rating (4.6 vs 4.2) and update cadence (every 3 days vs every 3 weeks). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. Engine Simulator sells 1 one-off in-app purchase and Engine Sim sells 15 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Engine Sim holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: Engine Sim has 1.1K ratings behind it against 141, so its average is the more settled of the two. Written reviews point the same way: 79% of Engine Simulator's written reviews are positive against 86% of Engine Sim's.

Engine Simulator ships an update every 3 weeks, Engine Sim every 3 days. Both last shipped on October 31, 2026.
