SEE WHERE YOUR LAP TIME GOES Created by a professional racing driver and instructor. Mount your iPhone, drive your session and get every lap timed, onboard video with telemetry and a corner-by-corner breakdown: where you braked too late and where you lost speed on exit. VIDEO WORTH SHARING Record with iPhone cameras or connect a GoPro. G-Box overlays lap time, speed, G-forces, track map and RPM on your video. Pick a race-car style dash or a vertical layout for social media. On supported iPhones, film both cameras at once: the road and the driver. ALL ON ONE IPHONE 25 Hz Fusion combines the iPhone's GPS and motion sensors to calculate a smooth driving line between GPS fixes, with no external receiver. These are calculated positions, not 25 Hz satellite measurements; results depend on GPS reception and phone mounting. Add a compatible OBD adapter for RPM, estimated gear and power, or an external GPS receiver: G-Box, RaceBox Mini, Mini S and Micro, and selected Dragy models. COMPARE YOUR LAPS • Automatic lap timing, live delta, sectors and predicted lap time • Speed, G-forces, RPM and delta on synchronized graphs and map • Braking, turn-in, apex and exit speed against your best lap • Friction Circle and a theoretical best lap from your strongest sectors • Session replay on 2D and 3D maps YOUR DATA, YOUR WAY Import sessions from RaceChrono, Harry's LapTimer, VBOX, Race Navigator, MoTeC and AiM.
