Test acceleration of your vehicle using Internal GPS or using external Dragy, RaceHF Bean, Racelogic VBox Sport and RaceBox.cc devices. 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.
For VBox Sport, go to device Settings -> Bluetooth and select your device. When it’s connected, in app go to Settings -> Devices and connect it.
For BLE devices like RaceBoxPro and RaceHF, go to Settings -> Devices and then connect.
Internal GPS device has precise location and speed, but it’s not updated frequently. On all devices it’s updated once in a second (1Hz). External GPS devices are 10 or 20Hz (VBox Sport has 20 updates in one second, RaceBox has 16Hz, Dragy has 10Hz). Yes, VBoxSport is 20 times more precise than your iPhone GPS.
On main screen, just rotate your device in landscape mode and it will start recording video as addition to your data. Be sure that rotation is not locked on your device.
If your run has recorded video, select that run from list of runs, go to “video” in top right corner, and chose “Overlay”. 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.
RaceBuddy use “One foot rollout” feature by default. If you use external device, you will get close results to timing slip. Note: Drag strips are using multiple optical sensors and they are calculating location of vehicle in space. GPS, with good refresh rate, is more precise!
