Trakio vs Himawari CIRCUIT

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.

Himawari Circuit turns a day at the track into something you can look back on. It times your laps with GPS and records your driving line, speed and G-force together. After the session you can see, on the map, where you were quick and where you lost time. AUTOMATIC LAP TIMING Every time you cross the control line, a lap is recorded, along with sector times, top speed and average speed. Each lap time is announced out loud, so you never have to look at the screen while you drive. Times are interpolated between GPS fixes, so a lap is not lost when there is no fix at the moment you cross the line. DRIVING LINES YOU CAN COMPARE Your line is drawn on the map, colored by speed or by G-force, so you can see where you are on the power and where you are not turning. Lay your own earlier runs over it, or line up runs from friends in the same group. In replay, up to four cars move at once, so you can watch the gap open up. YOUR SESSIONS ARE KEPT FOR YOU Sessions upload automatically when you finish. With no signal they stay on your phone and go up once you are back online. VEHICLES AND TIRES Record sessions per vehicle, with maintenance records and tire details, so you can trace how a setup changed your times. WITH YOUR FRIENDS Create a group to share sessions and leaderboards with its members. Live timing shows where your friends are on track, and their lap times, as they drive. EXTERNAL GPS RECEIVERS Works with RaceBox and DigSpice IV. A phone's built-in GPS updates about once per second; an external receiver updates far more often, which makes lines worth comparing. If the connection drops, recording falls back to the built-in GPS, so nothing is lost. WHAT YOU CAN TIME Circuits and closed courses, and point-to-point runs such as hill climbs. -------------------------------- PLANS The free plan covers lap timing, session recording, the track list and leaderboards, and cloud sync of your sessions.
