Even without being in a RaceTime circuit, the app will use the GPS information to show the speedometer and speed graph in real time. It will also calculate all the times related to your acceleration.
Acceleration measurement works thanks to the sensitivity of the GPS receiver installed on your smartphone, the time will be timed starting from the first movement of the vehicle until reaching the maximum speed. At the end of the test a table will be shown with the times that have elapsed from zero to all the target speeds and from zero to the maximum speed.
For a more detailed analysis of the speed it is possible to construct a graph showing the speed curve over time, from which you can extrapolate interesting information such as maximum torque point, gear shift time and much more.
