Hello ,
I want to discuss more about job with you.
I have ever developed a similar project what show speed of device.
The main function in your app is the speed sensor.
How to do this?
I am sure that only way to get speed of device is to use GPS.
But some issues are in GPS, So I want to interview with you .
Please contact me before awarding job to me.
I like to use skype for communication.
