REVBOX plays engine sound that follows how you drive. GPS and your phone's motion sensors work together, so the revs climb when you accelerate, drop when you lift off, and shift through a virtual gearbox in step with the car. DRIVE MODE Mount your phone, start the sound, and drive. Speed comes from GPS and the accelerometer combined, and throttle is read from how hard the car is pulling. Press harder and the gearbox kicks down; ease off and it upshifts and settles into a cruise. SIMULATION MODE Try every sound parked: hold the gas and brake pedals on screen and the virtual engine responds. Free for everyone. 50 ENGINE SOUNDS V8, V10, V12, V6, inline-4, inline-6, boxer, rotary, diesel, motorcycles, buses and trucks. Each pack has its own gear ratios, rev range and idle. BEST IN THE CAR Connect with a cable, CarPlay over USB or an AUX lead, for the lowest delay. Some cars buffer Bluetooth audio by one to three seconds, so the sound can lag behind your driving. TRIPS AND BADGES Every drive is logged on your device with distance, route, top speed and a driving score. 30 badges unlock extra engine sounds along the way. REVBOX PRO Free: Simulation mode and three engine sounds. Pro unlocks Drive mode and all 50 sounds. • Lifetime: $69.99, one payment, no renewal • Annual: $49.99 per year • Monthly: $9.99 per month Prices may vary by region. Subscriptions are charged to your Apple Account and renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel in Settings > Apple Account > Subscriptions. Keep your eyes on the road. Set up the sound before you drive.

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.
