EngineForge vs RevApp

EngineForge turns your iPhone into a live engine sound simulator. Pick an engine — inline-four, V8, flat-six and more — and EngineForge generates a real-time tachometer and exhaust note that responds to how you actually drive. NO ADAPTER REQUIRED EngineForge reads your speed and acceleration straight from your iPhone's GPS and motion sensors, revving the simulated engine as you accelerate and settling as you cruise. WANT REAL DATA? Connect a Bluetooth OBD2 (ELM327) adapter to drive the revs from your car's actual throttle position. Electric vehicle mode reads speed instead of throttle. CARPLAY READY See your custom tachometer right on your car's display. FEATURES • Build your own engine: layout, cylinder count, displacement • Real-time tachometer with redline • Engine audio that rises and falls with your speed • GPS + motion revs — works with no extra hardware • Optional OBD2 support for live throttle • Electric vehicle mode • CarPlay dashboard • Adjustable volume EngineForge is for entertainment. Always keep your eyes on the road and follow all local laws.

Feel the engine, not just hear it. RevApp: Engine Lab turns your iPhone into an engine you can drive.
