I just downloaded this to my phone. I have a windshield suction cup mount. Depending upon your phone and memory. It is a free app to try and download. If you want the graphics imbedded you have to pay a small fee to enable this. It also has a sport mode. Accel and braking distance and time.
I'm still playing with it so I don't have all the answers.
Best part is it is free to try.
