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.
