Trakio vs G

Trakio — GPS Lap Timer for Track Days Trakio is a focused lap timing app built for drivers who want clean data and zero distraction on track day. Open the app, select your circuit, and drive — Trakio handles the rest. Pre-Session Checklist Before you head out, Trakio confirms you're ready: GPS signal strength, battery level, and start/finish line configuration. No surprises on your out lap. Auto Circuit Detection Trakio uses your location to automatically identify your nearest circuit and pre-select it for you. Check the weather conditions and wind at the track, then name your session and go. GPS Lap Timing Laps are timed automatically as you cross the start/finish line — no buttons to press while driving. Run it on your iPhone's GPS, or pair a Bluetooth receiver for a faster, sharper data stream. External GPS Support Connect a Qstarz BL-1000GT / BL-818GT or a RaceBox Mini, Mini S or Micro, and Trakio times your laps from a 10-25Hz stream instead of the roughly 1Hz your phone provides. Crossings land where you actually crossed and sector splits hold up. Circuits Around the World Search in English or Japanese, filter by country, sort by what's nearest, and star the ones you run most. Every circuit is drawn with its real outline, so you know a track by its shape. Session Analytics After each session, dive into your data: - Best lap time - Top speed - Lap consistency score - Theoretical best lap (your best sectors combined) - Lap delta trend — see if you were improving or fading - Full lap-by-lap breakdown with gap to your best GPS Trace on Satellite Map Each session shows your smoothed GPS line overlaid on a satellite map of the circuit, with start/finish and sector lines marked. Session History Your session history is stored on-device. Search and filter by all sessions, recent, or your best runs. Rename sessions, log your car, add notes, and track your progress across every visit to every circuit. Global Leaderboard Optional, and entirely up to you. Post a lap to the leaderboard for a circuit and see where it lands against other drivers. Nothing is published unless you choose to share it. Share Your Results Share your session highlights as an Instagram Story — choose a template, add a background photo, and post your best lap straight from the app. Trakio Pro Trakio is free to try with 3 saved sessions. Trakio Pro unlocks unlimited saved sessions, PDF lap time sheets, and CSV lap exports. Available as a yearly auto-renewing subscription or a one-time lifetime purchase. The yearly plan renews automatically unless canceled at least 24 hours before renewal, and is managed in your App Store account. Payment is charged to your Apple Account. Designed for the Track - Dark mode for early morning sessions - Available in English and Japanese - No account required — sessions, laps and notes stay on your device. Only a leaderboard time you choose to share leaves it. Circuit outlines are derived from OpenStreetMap data, © OpenStreetMap contributors, ODbL 1.0.

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/
