This App is designed to track your position on the Map, and measures your Speed. You may display the speed digitally in Metric or Miles. The slider is used to generate an audio warning to let you know that you passed the Level and should slow down. This is good for those who forget to pay attention to their speed.
To share Photo feature, you need to run similar app on another device and both device using same WiFi to connect and transfer pictures.
