Verdict

The call

The clearest difference is in-app purchases: Engine Sounds at none against RealEngineSim's 3. Engine Sounds also leads on review sentiment (100% vs 72%). RealEngineSim's advantage is ads (none vs shown) and update cadence (weekly vs every 3 months). On price and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

RealEngineSim holds the better App Store score, 3.8 against 3.5. That said, the two scores are not equally well evidenced: RealEngineSim has 83 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 72% of RealEngineSim's written reviews are positive against 100% of Engine Sounds's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

RealEngineSim ships an update weekly, Engine Sounds every 3 months. The most recent releases landed on November 1, 2026 and November 9, 2026 respectively.
