Wrumer vs EVRoar

Wrumer connects* to your car's internal computer and its speakers. It reads the car's RPM speed and throttle application and based on that plays an enhanced engine sound through your car's speakers. You can choose between multiple car engine sounds and effects, such as a Turbo Whistle and Backfires. *For the app to connect you also need the Wrumer device. You can get the Wrumer device at https://wrumersound.com.

Your EV is silent. Your heart isn't. EVRoar turns your phone into an engine. Pick a thundering V8, a screaming V10, a turbine-smooth V12, or a cinematic electric drive sound — then drive. EVRoar reads your motion and plays an authentic, gear-shifting engine note through your car's speakers, live. Built for petrolheads who went electric — and anyone who misses the noise. REAL ENGINES, NOT A SOUNDBOARD • Nine distinct engines: cross-plane V8 burble, flat-plane exotic, V10 wail, V12 hypercar, classic muscle, turbo flat-six, vintage oldtimer, exotic supercar, and a futuristic EV synth. • Firing-order accurate — a cross-plane V8 burbles because of its uneven firing pattern, and EVRoar models it. • The sound reacts to load: accelerating sounds different from coasting, with backfires and overrun crackle on lift-off. DRIVEN BY YOUR DRIVING • Uses your phone's GPS, accelerometer and gyroscope to turn real motion into revs. • Simulated automatic gear shifts — feel the shift, hear the bark. • Instant throttle response, tuned for how a real engine loads up. MADE FOR YOUR CAR • Plays through your car's audio over Bluetooth or AirPlay. • Recovers automatically after phone calls and navigation prompts. • Runs in the background with the screen off. MAKE IT YOURS • Configure your vehicle: top speed, number of gears (1–8), and shift style — relaxed, medium or sport. • From a 30 km/h e-bike with 3 gears to a 300 km/h hypercar with 7. • Fine-tune the sensor mix (accelerometer, gyroscope, GPS) and overall sensitivity. TRY IT ANYWHERE • Simulator mode gives you on-screen gas and brake pedals — test every engine from your couch, no driving required. EVRoar is for entertainment. Sound plays inside your own vehicle; you remain responsible for road safety and local regulations. All engine sounds are original, generated audio.
