This is my first app on google play, I made it with appyBuilder (thanks! ).
App automatical recognizes entry on highway and it start control of apx.speed. (in Serbia limit is 130km/h and they control it on exit toll gate)
On exit You will recive price between toll gates, apx. speed and time.
It can also be used outside the highway.
In this application, it is interesting my try app work in the background.
I do that with Advance location Sensor.
For every 5 star rating on google play THANKS!
