Give your EV a soul.

Real engine sound, driven by how you actually drive – through your car's speakers.

28 engines

Flat-six, V8, V10, V12, rotary, boxer and more – Euro, Muscle, JDM and Exotic.

Follows your right foot

GPS and motion sensors turn your acceleration, lift-offs and braking into revs and gear changes.

Turbo & crackles

Blow-off, flutter, pops and crackles – Sport mode holds the revs and flat-shifts.

Plays in the car

CarPlay or Bluetooth, with the screen locked. Mix it with your music or navigation.

Answers to the most common questions. Still stuck? Contact us below.

How do I get the sound through my car's speakers?

Connect your iPhone to the car with Bluetooth or CarPlay, open Revline, press Start and drive. Turn the car's volume up – Revline plays like music. In Settings you can make it start automatically when your car's audio connects.

Where should my phone be?

In a car mount, so it can't slide around. Revline feels the car move through the phone's sensors – if the phone moves on its own, the sound gets confused. Set everything up before you drive and keep your eyes on the road.

The revs don't match my driving.
  • Make sure Location is set to "While Using" or "Always" with Precise Location on (iOS Settings › Revline › Location).
  • Pick how strongly your car slows when you lift off in Settings › Your car's regen.
  • Adjust Throttle sensitivity in Settings › Driving.
  • GPS needs a clear view of the sky – underground car parks and tunnels confuse it.
What's the difference between Comfort and Sport?

Comfort shifts early and smoothly for relaxed driving. Sport holds the revs longer, blips on downshifts and crackles more. Tap the big UP and DOWN paddles to change gears yourself.

My music is too loud or too quiet next to the engine.

In Settings › Car, "Mix with music & navigation" plays both together, and "Lower music while driving" turns your music down while the engine runs. The engine's own volume is in Settings › Sound.

How do I restore my purchase or cancel my subscription?

Restore: Settings › Restore Purchases in the app (use the same Apple ID you bought with). Lifetime is a one-time purchase – it never renews and there is nothing to cancel. Weekly subscription: cancel or change it in iPhone Settings › your name › Subscriptions › Revline, at least 24 hours before the renewal date to avoid being charged for the next week.

How do I report a problem?

In the app: Settings › Report a problem. Attach your latest drive logs – they show us exactly what happened (motion and speed data only, never your location).

Is it legal to play engine sounds in my car?

Revline plays inside your car, like music. Keep the volume at a level where you can still hear emergency vehicles and your surroundings, and follow your local rules on in-car audio.
