Didn't know where to put this thread so put it here. I have not had a chance to actually test this app yet as I don't have a motorbike handsfree but I found his app today and it has a function I thought would be handy for those that play music through their Android phone. Speed Volume Control, basivally what it does is use GPS to determine your speed, raising and lowering your volume the faster or slower you are going. So say you are stationary in traffic you could set it to 50% then once you get going say over 50 or 60kmh and your bike is revving off its guts or the wind noise going wild it will automatically increase to whatever you set it to say 80% or 100%. Let me know how you go if anyone decides to try it, there is a paid and free version I am not sure of the functionality restrictions between them.
