An iPhone sound experience
Your drive,
with a voice.
RevTone synthesizes expressive engine sound that follows your drive. Choose a sound, secure your phone, and start while parked.
Original sounds
Eight individually tuned, real-time synthesized engine profiles, each with its own character.
Phone-based response
Your iPhone estimates speed and movement. RevTone does not connect to or control your vehicle.
Try the route
Explore each sound in a 2 km simulated drive before taking it on the road.
Built for considered use
Set up RevTone while parked. Keep the phone mounted securely and follow local driving laws. The displayed RPM and gear are simulations; RevTone is not a driving instrument or navigation app.
