Engine Lab: Simulator & Sound app analytics for October 25

Build an engine and hear it run. Engine Lab is a touch-first engine simulator: design anything from a single to a V12, then hear it idle, rev and pull to the limiter, live on your iPhone or iPad. BUILD BENCH • Set the layout, 1 to 12 cylinders, bore, stroke, firing order and redline. • Hear each change as you make it, and hold to rev. • Try different headers, exhausts and mufflers. • Compare against a saved version by ear or on the dyno. SEE IT IN 3D • Every engine, including your own builds, becomes a 3D model driven by the live simulation: pistons, crank, cams, valves and glowing headers. • Orbit, zoom, slow it down, switch between X-ray and solid, and tap any part for live readings. The classic 2D cutaway is one tap away. DRIVE IT • Manual or automatic gearbox with clutch and road speed, plus a gearing chart with top speed in each gear. • Simulated dyno pulls with torque and power curves. • Six built-in engines: Honda B18C5 VTEC, Honda TRX520 single, BMW M52B28, Toyota 2JZ, Audi 2.3 inline-5 and GM LS V8. IMPORT AND SHARE • Import engine-sim .mr scripts and share your builds as .mr files. • Export a WAV recorded by the on-device simulator. No account, network service or microphone permission is required. An optional one-time Pro purchase unlocks advanced tuning and unlimited saved builds; the free plan keeps three. Values are simulated estimates for exploration, not certified engineering measurements.
