RevForge: Engine Sounds

Start the engine, press the gas pedal and shift through an H-pattern gearbox. RevForge is an interactive engine sound simulator: its voice is synthesized live from engine speed, load and throttle, so every rev, shift and lift changes the sound as it happens.

DRIVE IT ON THE SCREEN
No car or adapter needed. Turn the ignition, work the clutch, brake and throttle, and move the lever yourself.
• Manual H-pattern, automated-clutch, sequential and automatic gearboxes
• Launch control, engine braking, wheelspin and a rev limiter
• Starter, idle, gear-change and shutdown sounds
• A handbrake and three working pedals when the gearbox calls for them

EXPLORE THE ENGINE LIBRARY
Compare car engine sounds built from each configuration's layout, displacement, firing order and aspiration. Hear single-cylinder engines, inline and flat layouts, V8s, V10s, V12s, V16s, rotaries and electric motors. Turbo engines spool, blow off and change character under load.

TUNE THE ENGINE AND EXHAUST
Shape the idle, load, intake, exhaust sounds, turbo, pops, overrun and shift character. RevForge Pro opens the full tuning tree, a four-band EQ for each voice, and the full engine catalog and builder.

CONNECT YOUR OWN CAR OVER OBD2
Use a compatible adapter that speaks the ELM327 command set over Bluetooth Classic or BLE. RevForge reads the revs, speed, load and available sensor values from the vehicle, then drives the sound from what the real engine is doing. What the dashboard can show depends on what your car reports.

BUILD YOUR DASHBOARD
• Rev counter and shift lights
• Boost, coolant and fuel when the car provides them
• G-meter, power chart, minimap with real streets and media control
• Rearrangeable modules for phones and tablets, portrait or landscape
• Instrument styles and themes from clean digital displays to classic dials

TRIPS, LAPS AND RUNS
Record drives, time laps across a line you place on the map, and measure acceleration, quarter-mile and braking runs from real speed. Saved results can become images you share through Android's share sheet.

YOURS, ON YOUR PHONE
There is no account, login, advertising or analytics. Saved drives, cars and tunes stay on your device. Location is optional. Real-street fetching for the minimap can be switched off; when it is on, the app sends an approximate map square to OpenStreetMap's Overpass service.

FREE AND PRO
Free includes the simulator, OBD-II connection, dashboard, trips, circuits and performance runs, two themes and three engine configurations: a naturally aspirated V8, a V6 and a turbo inline-five. RevForge Pro is one permanent Google Play unlock for all 139 shipped engine configurations, the full catalog and builder, the full tuning tree with EQ and every theme.

RevForge supports Android 9 and newer on phones and tablets.
