RN Analyzer is the analysis app for the Race Navigator. Download laps and videos from the recorder over its Wi-Fi, and the app shows you where the time goes. WHERE THE TIME GOES Compare a lap with your best lap in one tap, or choose up to ten laps of a track yourself. The gap chart shows in red and green where you lose and where you gain, the videos of the laps run side by side, and one cursor runs through the charts, the map and the videos at the same time. CORNER COACH For every corner: braking point, apex, throttle point, exit speed and the grip used, the time lost and where it goes, and a what-if: "+5 km/h at the apex ≈ −0.12 s". A short summary, written on the device, follows the facts. 3D CHASE VIEW Flip the map to a camera behind your car on satellite imagery: every lap on its own line, brake lights that light from the data. TRACK MAP Coloured by time gained and lost, by grip, by driving phase or by any channel such as the gear, with the braking points and apexes of the laps shown. HIGHLIGHTS AND NOTES The hardest braking, the biggest losses and the moments off the line, found in the telemetry. Pin a note at the place something happened. One tap takes the cursor and the videos there. PRO TELEMETRY Charts with up to six channels, channel strips with the corners on top, an X-Y chart of any two channels, math channels from a library or your own formulas, CAN channels, limits per car, sector times and your own sectors, Excel export by distance or by time. THE DRIVER IN THE DATA With your permission, heart rate, HRV, breathing, blood oxygen and body temperature from Apple Health, as channels in the charts and the heart rate on the video. Start a workout on your Apple Watch before you drive, and the heart rate runs through every lap. Steering, throttle and brake in the video when the car's data has them. RACE NAVIGATOR INSIDE Laps and videos over the recorder's Wi-Fi, no firmware change. Recording, driver, car, track and video settings, the camera preview and RN software updates from the same app. SHARE Send a lap, or just a part of it, with its video to a teammate, who compares it with their own laps. Your notes go with it, your health data only if you choose so. YOUR DATA STAYS YOURS No account needed. Everything is stored on your device, and in a cloud folder of your own if you choose one. The laps and videos of RN Analyzer for iPad are taken over in place. Requires a Race Navigator recorder for the direct connection; .rnz and .mp4 files can be imported without one. A guided tour with two sample laps shows everything before you connect. In 20 languages.

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. YOUR FIRST TRACK DAY WITH PRO Your first 3 sessions with laps are recorded with full G-Box Pro and stay unlocked for good: where you lose time, video, overlays and lap comparison. Sessions without laps don't count. FREE AND PRO Free: lap timing with iPhone GPS, map and speed graph, session import, OBD logging, and a preview of the analysis: how much time you could gain and in which corners. G-Box Pro: the full analysis with time lost per corner, causes and tips, 25 Hz Fusion, video recording and overlays, lap comparison, all telemetry channels, OBD power and external GPS receivers. Pro is a one-time purchase, not a subscription, and includes 1,000 credits for AI analysis. More AI credits are available in separate packs. Location access is required for GPS lap timing. For closed race tracks only. Set up your phone before driving and never operate it while driving. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
