RevLab - Engine Simulator
RevLab is a physics-based engine simulator for iPhone, iPad and Mac. Instead of playing recordings, it computes the crank, pistons, valves, combustion and exhaust flow in real time, and that one simulation drives the sound, haptics, gauges and a 3D engine. 21 engines from a V-twin to a quad-turbo W16, rotaries, race hybrids and an EV, with manual, DCT, automatic and sequential gearboxes, a drag strip and 60 Game Center leaderboards. Freemium with a one-time $4.99 Pro upgrade.
