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 ratings volume: Engine Simulator at 136 against PolyCar Lab Time Attack's 1. Engine Simulator also leads on rating (4.2 vs 4.0) and chart position (#60 vs unranked). PolyCar Lab Time Attack's advantage is review sentiment (100% vs 79%). On price, update cadence, ads and in-app purchases 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. PolyCar Lab Time Attack sells 1 one-off in-app purchase and Engine Simulator sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Engine Simulator holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: Engine Simulator has 136 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of PolyCar Lab Time Attack's written reviews are positive against 79% of Engine Simulator's, so the app with the better star average is not the one people write more warmly about.
PolyCar Lab Time Attack ships an update monthly, Engine Simulator every 3 weeks. Both last shipped on October 25, 2026.
