RevLab - Engine Simulator

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.

Message from the founder

"Solo developer selling for personal reasons. Launched Oct 7, 2026: 20,000+ downloads and 115 Pro purchases in three weeks. Finished and stable on iPhone, iPad and Mac, no servers or running costs. Upside: conversion is only 0.6%, no Android version yet (the Rust core is platform-independent), and sales so far paid Apple's standard 30% cut; under the Small Business Program (15%) the same sales yield about 21% more. Includes full source code and a 37-second trailer."
