Smart Bike Horn

A smart bicycle horn application designed to keep you safe and alert pedestrians and obstacles quickly during your rides.
It is optimized to be mounted on a smartphone holder/mount of a bicycle or motorcycle and used intuitively like a physical warning horn.
With no complex operations required, you can trigger sounds instantly with a single tap or by simply shaking your device.
