Test acceleration of your vehicle using Internal GPS or using external Racelogic VBox Sport.
Race buddy helps you to measure acceleration from standstill or while you are rolling. It has ability to record video and overlay all your data (speed, temperature, G-force, altitude,...) over your video and you can share it with your friends.
These are frequently asked questions. If you have any question, proposition or feature request, feel free to contact us.
Go to device Settings -> Bluetooth and select your device. When its connected, app will detect device and use it. Note: You need to purchase add-on to be able to use External GPS. Go to Settings -> Buy Addons.
What is different between internal and external GPS devices?
Internal GPS device has precise location and speed, but its not updated frequent. On all devices its updated once in a second (1Hz). External GPS devices are 5, 10 or 20Hz (VBox Sport has 20 updates in one second!). Yes, VBoxSport is 20 times more precise then your iPhone GPS.
If your run has recorded video, select that run from list of runs, go to “video” in top right corner, and chose “Export”. Overlay is done frame by frame and it takes few minutes. When overlay is done, you are able to share that video with friends online.
To get the same results like on your drag strip, go to settings and enable feature “One foot rollout”.
