Engine Simulator is a physics-based piston engine sandbox. The sound and motion come from a real rigid body simulation of the crank, pistons, valves, and combustion, not recordings. Start an engine, work the throttle, and tune its fuel and ignition maps in the ECU. Build one from scratch (layout, bore, stroke, cam, firing order) or describe what you want and have it generated on device. Watch it run in 3D, read live power and torque on the dyno, or push it past the limiter until it breaks. Post your engines to the global leaderboard and compare against other builders. Engine Simulator for iOS is an unofficial port. It is not affiliated with, endorsed by, or supported by AngeTheGreat (Ange Yaghi), the creator of the original open source Engine Simulator.

Verdict
The clearest difference is ads: Engine Simulator at none against GT Rivals's shown. GT Rivals's advantage is rating (4.7 vs 4.3). On price, review sentiment, ratings volume and update cadence 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. GT Rivals sells 9 one-off in-app purchases and Engine Simulator sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
GT Rivals holds the better App Store score, 4.7 against 4.3. Both are backed by a comparable volume of ratings — 433 and 216 respectively. Written reviews complicate that: 69% of GT Rivals's written reviews are positive against 76% of Engine Simulator's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on November 9, 2026 and November 10, 2026 respectively.
