SEE WHERE YOUR LAP TIME GOES Created by a professional racing driver and instructor, G-Box turns the iPhone you already own into a track-day lap timer and telemetry tool. Start free with iPhone GPS Standard. Unlock G-Box Pro for 25 Hz Fusion and advanced lap analysis. 25 HZ FUSION. JUST YOUR IPHONE. G-Box Pro combines the iPhone's built-in GPS and motion sensors (IMU) to calculate your driving line at 25 Hz. No external GPS receiver is required for Fusion. Review a smoother estimated trajectory between GPS fixes, then compare braking zones, corner speed and acceleration on exit. These are calculated position updates, not 25 Hz satellite measurements. Results depend on GPS reception, phone mounting and sensor calibration. TIME EVERY LAP • Automatic lap timing with current, previous and best lap • Live delta, sectors and predicted lap time • Create or load tracks and organize your sessions • Metric and imperial units FIND THE DIFFERENCE BETWEEN TWO LAPS Compare speed, lateral and longitudinal G, available RPM and lap delta on synchronized maps and graphs. Inspect braking, turn-in, apex and exit speed. Explore the Friction Circle and a theoretical best lap assembled from your strongest sectors. BRING YOUR EXISTING DATA Import supported telemetry from RaceChrono, Harry's LapTimer, VBOX, Race Navigator, MoTeC and AiM. Connect compatible external GPS receivers, including supported G-Box, RaceBox and selected Dragy models. Add speed and RPM from compatible OBD hardware. Available channels depend on your equipment and source files. PUT VIDEO AND DATA TOGETHER Record with iPhone cameras or connect a compatible GoPro. Synchronize video with telemetry, compare laps during playback, and export overlays with lap time, speed, G-forces, map and available RPM. Replay sessions on 2D and 3D maps. PLAN YOUR NEXT STINT Review local corner-by-corner analysis of braking and corner exit. Optional AI analysis offers another perspective on your telemetry. Export your calculated Fusion route and supported telemetry formats, including GBO, CSV, VBO, GPX, KML and NMEA. Start now with the included Nürburgring Nordschleife BTG demo lap (8:06), or bring your previous sessions. Supported imports include RaceChrono RCZ/VBO, Harry’s LapTimer HLPTRL/CSV and RaceBox VBO exports. Save your export to Files, then open Sessions > Load in G-Box. FREE TO START. PRO WHEN YOU NEED MORE. FREE: Record laps with iPhone GPS Standard, view maps and speed graphs, import supported sessions, and connect and log compatible OBD data. Overlay templates remain available to preview. PRO: Calculated 25 Hz Fusion, external GPS receivers, lap comparison, additional channels (G-forces, RPM and pedal position), corner analysis, advanced OBD power analysis and AI analysis. Video recording, import, playback, synchronization and overlay export require Pro. Cloud AI uses separate credits. Choose a one-time Lifetime purchase or a monthly subscription. Existing purchases and annual subscriptions remain supported. Location access is required for GPS lap timing and telemetry. For closed race tracks only. Mount and set up your phone before driving. Never operate it while driving. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is update cadence: G at every 4 days against RDRC's fortnightly. RDRC's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 17.0). On price, review sentiment, ads and in-app purchases there is nothing between them.
