install the smartphone flat into the car (perhaps center console)
it should be connected to the car to keep it from skidding
install it lengthwise to the driving direction
search for a straight flat street without hills or ditches
look out for traffic - do not use this app on streets with other cars around
your car has to be in idle mode... then start the measurement
the app will calibrate itself (you will see a black screen with spinning wheel)
if it's ready you see the orange "recording data"
now accelerate as fast as your car is able to
then decelerate as fast as your car is able to
----- you can repeat this as often as you wish, you don't have to reset the data
----- the top acceleration doesn't have to be in on turn .... for instance you can top accelerate one turn in first and third gear and next turn in second gear (the app accumulates the data)
----- you don't have to collect all the data up to top speed (it's not possible everywhere) ... collect as much as you can
