Realistic accelerometer-based car & motorcycle sounds for cycling.

Cycling has never been this hilarious! With Wroom you can make your bicycle sound like a sports car or a motorcycle like never before.

Wroom uses the accelerometer on your phone to determine how fast you are pedaling and changes the engine sound accordingly. It even simulates gear changes for ultimate realism!

How to use Wroom

1. Connect your phone to a Bluetooth speaker for maximum loudness!

2. Set your sensitivity and engine sound in the app.

3. Put your phone in your pants front pocket. This is important because the sound is based on how fast your leg moves.

4. Hop on your bike and start the engine by kick-starting it or by tapping on the screen.

5. Go have some fun! When you are done, tap the screen to turn off the engine.

Wish it had GPS speed instead of leg movement

This was a big bummer on my E-scooter because you need to move your legs and pedal for the sound to work instead of it being based on GPS speed.

Hope this gets added in the future then I will continue using this app.
