RevApp: Engine Lab

From a screaming V12 to a turbocharged 16-cylinder – rev them, shift them, hit the limiter. Now with Retro Cruise. Three engines free, no subscription.

Feel the engine, not just hear it.

RevApp: Engine Lab turns your iPhone into an engine you can drive. Hold the throttle and the revs climb, shift up and the sound drops into the next gear, lift off and the exhaust crackles on the overrun. Every engine has its own physics, gearing, limiter and instrument cluster.

A GARAGE FULL OF ENGINES Naturally aspirated V12s and V10s, a flat-six, twin-turbo V8 and V6, turbocharged inline-six and inline-four and a turbocharged 16-cylinder – each with its own character. A visualized sound-game where you can drive every car in 5 different maps.

DRIVE IT • Hold to accelerate, paddle-shift up and down • Rev limiter, blips on downshifts, pops and crackles • Pedal Mode with a real 0–100 % throttle, Flow Mode for one finger • Outside, cockpit, dyno and tunnel sound • Haptic feedback on every shift • Drive-away and fly-by scene with distance, Doppler effect and surroundings

RETRO CRUISE A pixel driving game right above the pedals: cruise through 4 cities with traffic lights, tunnels, roundabouts and rain – your engine sound follows every move.
