A free app for Android, by Car Logic.

VoomVoom is a simulator of the car’s engine sound. You can choose between different vehicles and have fun with them. All the sounds are recorded from real sports cars, and you can choose between standard and professional modes.

The standard mode is suitable for those who want to have some fun and enjoy the driving experience. This mode uses your device sensors (accelerometer and GPS) and matches your real-time driving.

The professional mode is suitable for those who want to enjoy a more realistic experience. Only those who are subscribed to one of  VoomVoom’s plans will have access to this.
