RevIt is a car engine sound simulator for iPhone. You start a car's engine, press a virtual gas pedal and shift a 6-speed manual gearbox while the app generates the engine sound live in real time. It includes 25+ cars with V8, V10, V12, inline-6, flat-6, boxer and rotary engines. DRIVE MODE – THE ENGINE SIMULATOR Every engine sound is generated live, not a recorded loop. The sound reacts to exactly how hard you press the pedal, so no two revs sound the same. • Gas and brake pedals – press to rev, slide down to floor it • 6-speed manual gearbox – shift the H-pattern stick straight or diagonally • Rev counter, speed and gear readout with a rev limiter • Pops and bangs when you lift off the throttle, plus Straight Pipe mode for a louder exhaust • Haptic feedback that pulses with the engine • Realistic performance – each car matches its real-world 0–100 km/h time and top speed • Hold the revs at the limiter too long and the engine blows, so you have to start it again 25+ CARS, EVERY ENGINE TYPE • Cross-plane and flat-plane V8 muscle and track cars • V10 and V12 supercars • JDM cars: turbo inline-6, rotary and inline-4 • Boxer-4, flat-6 sports cars and an Italian V6 Tap the heart to save cars to your garage. FREE VS. PRO RevIt is free to download. Some features require a paid Car Sounds Pro subscription: • Free: browse all cars, save cars to your garage, and drive any car by watching a short video ad.
