WHERE YOU LOSE TIME — A G-BOX SIGNATURE FEATURE Open a lap and G-Box shows on the map which corners cost you time and how many tenths. No digging through telemetry graphs: it's fully automatic, right on your iPhone. Works with G-Box recordings and sessions from RaceChrono, AiM, MoTeC, TraqMate or Race Navigator. The benchmark is your own car on your own tires: the best pass through each corner from that car's fast laps (within 3.5% of the best) on the same track that day — not someone else's record. Tap a marker for the cause in plain words (braking too early, a slow exit) and what to do on the next lap. "Compare with lap N" puts the faster lap on the graph and map in one tap. Created by a professional racing driver and instructor. 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, such as OBDLink MX+, 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 • Every corner in one table: this lap, the day's best pass and the difference in braking, turn-in, apex and exit speed • Speed, G-forces, RPM and delta on synchronized graphs and map, against any lap from any session on the same track • Friction Circle and a theoretical best lap from your strongest sectors • Car class from power-to-weight and tire grip: performance points, SPORT to GT4, and leaderboards by track • Session replay on 2D and 3D maps YOUR DATA, YOUR WAY Import sessions from RaceChrono, Harry's LapTimer, VBOX, Race Navigator, MoTeC, AiM and TraqMate. Export to GBO, CSV, VBO, GPX and NMEA. TRY IT BEFORE YOUR TRACK DAY Open the included Nürburgring Nordschleife demo lap (8:06) to explore maps, graphs and lap timing before your first session.
