# Engine Sim vs Exhaust Note

The clearest difference is ratings volume: Engine Sim at 1.3K against Exhaust Note's 14. Engine Sim also leads on chart position (#103 vs unranked). Exhaust Note's advantage is review sentiment (94% vs 83%). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Engine Sim sells 10 one-off in-app purchases and Exhaust Note sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for Engine Sim against 4.7 for Exhaust Note. That said, the two scores are not equally well evidenced: Engine Sim has 1.3K ratings behind it against 14, so its average is the more settled of the two.
