RealEngineSim is a simulation game that you can enjoy the real engine sound of cars and motorcycles made by the innovative engine sound synthesis technology. RealEngineSim uses technology completed through years of research by engine sound professionals in Hamamatsu, a region known as a home to the world’s automobile and motorcycle manufacturers. Using this technology, we have created the world’s only iPhone app able to regenerate real engine sounds. ○This app is a simulation game in which you can enjoy the speed control and the innovative engine sound of manual mission vehicles. ○The use of a speaker gives you even more realistic and muscular sound. However, we would ask you to enjoy this app with an earphone or a headset when using it in public places. (* Please be extra careful of the volume in order not to either hurt your hearing or trouble people around you.) ◆ Available vehicles ◆ Four types: passenger cars, sports cars, sports motorcycles, and racing cars. You can also enjoy controlling the acceleration, braking, clutch, and shifting of manual transmission vehicles (Auto-Clutch available). *There are eight additional engine sounds available for in-app purchase. ◆ Pursuing realistic engine sound ◆ Precise vehicle models and innovative engine sound synthesizers were used to achieve real engine behavior and powerful engine sound that cannot be experienced through other racing games. Features life-like tire slippage caused by sudden acceleration and braking. ◆ The Driving Mode ◆ There are two modes: free driving and speed tracing Speed tracing is a game in which the object is to drive at a specific target speed. Expert mode features the racing speed data from racing cards driving on famous courses from around the world, giving you the chance to experience the excitement of racing on real courses. * The game modes, such as the chicken race, are available for in-app purchase. * The new technology of engine sound synthesis used in this app was developed by an engineer, who started his own business after a long time research on the sound at Yamaha Motor Co.,Ltd. (motorcycle manufacturer). The patent application is now in preparation. ◇For information and inquiries on our engine sound The engine sound synthesis technology used for this app is available for use in a variety of medias such as games, movies, and so on.

Verdict
The clearest difference is rating: RevHeadz Engine Sounds at 4.3 against RealEngineSim's 3.8. RevHeadz Engine Sounds also leads on ratings volume (1.4K vs 83). RealEngineSim's advantage is ads (none vs shown) and update cadence (weekly vs every 3 months). On price, review sentiment, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. RealEngineSim sells 3 one-off in-app purchases and RevHeadz Engine Sounds sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
RevHeadz Engine Sounds holds the better App Store score, 4.3 against 3.8. That said, the two scores are not equally well evidenced: RevHeadz Engine Sounds has 1.4K ratings behind it against 83, so its average is the more settled of the two. Written reviews complicate that: 72% of RealEngineSim's written reviews are positive against 69% of RevHeadz Engine Sounds's, so the app with the better star average is not the one people write more warmly about.
RealEngineSim ships an update weekly, RevHeadz Engine Sounds every 3 months. The most recent releases landed on October 21, 2026 and October 26, 2026 respectively.
