KartTrackerAI Race Performance vs Fox + Son Jetmax

Your kart has a history. KartTrackerAI 4.0 brings iOS 27 Apple Intelligence and advanced Siri integration to recording, reviewing and learning from every session. iOS 27 AND APPLE INTELLIGENCE KartTrackerAI supports iOS 27 while remaining compatible with iOS 18 and later. On eligible iOS 27 devices, supported photo analysis can use Apple Private Cloud Compute alongside OpenAI and Claude. When cloud providers return no usable result, a compatible on-device Apple Intelligence model can be tried for supported images. AI photo processing requires an active AI Image Processing subscription. Apple features depend on device eligibility, OS version, language, region, model readiness, connectivity, service availability, and usage limits. AI results may be incomplete or incorrect; review extracted details before saving. Photo analysis can be turned off in Preferences. ADVANCED SIRI INTEGRATION ON iOS 27 Keep your kart history within speaking distance. Ask Siri to look up a kart, read a session's recorded best lap, lap count and finishing position, or open Maintenance, Tires and Analysis. Start a new-session workflow for a selected kart, then review the setup and tap Create. Open session results to capture lap times and driver feedback when you return from the track. Try “Read session results in KartTrackerAI.” Team access and feature requirements still apply. TURN RECORDED LAPS INTO A CLEARER NEXT MOVE On compatible Apple Intelligence devices, the Analysis workspace brings together personal bests, recorded setup changes, gearing and tire-pressure baselines, lap consistency, and track conditions. Build a shareable Event Report from completed sessions at one track, including results, setup, weather, photos, and suggested next experiments. Analysis and report generation depend on model and language availability. A FRESH LOOK FOR RACE DAY A colorful garage puts your karts and next session up front. Clearer kart and session screens use alternating row colors, larger controls, and organized setup sections to make trackside entry easier. Playful motion and save celebrations bring the paddock to life, with support for Reduce Motion. SET UP. HEAD OUT. KEEP THE RESULT. Start a session from your garage, return to unfinished sessions, and keep chassis settings, gearing, tire pressures, weather, photos, notes, and results together. Prominent lap times and personal-best celebrations help you recognize progress against your recorded history. KEEP THE WORK BETWEEN SESSIONS Record maintenance for each kart: work performed, parts, notes, costs, engine hours, and lap count. Optional AI processing also supports photo and voice entry and official results-sheet import. Optional team synchronization helps drivers, parents, mechanics, and coaches work from the same kart history. WORK IN YOUR TEAM'S LANGUAGE Use the interface, Analysis, and Event Reports in English (US and UK), Spanish (Mexico and Spain), Polish, German, French, Brazilian Portuguese, Traditional Chinese, and Dutch. Supported image workflows let you choose source and output languages separately. Session notes remain as entered. The paid download includes local kart, setup, session, tire, photo, results, and maintenance tracking. Some optional processing and team synchronization features require a subscription. Availability varies by feature. Subscriptions automatically renew unless canceled at least 24 hours before the end of the current period. You can manage and cancel subscriptions in your App Store account settings. KartTrackerAI supports trackside judgment. It does not replace the driver or mechanic, and recorded associations do not prove that a setup or maintenance change caused a performance result.

Precision jetting made easy — This app helps you calculate jetting for Rotax engines based on weather and altitude. Now every Rotax racer has access to the same jetting Fox + Son has used to power our engines to countless Rotax National wins and Grand Finals tickets. After many months of development and testing, we have successfully brought the same jetting algorithms we use on our dyno to a quick, easy-to-use app. We have also included all of our popular Rotax tuning tips that are found on our website, along with a handy interactive gear chart for your convenience. As we do with our website, we will continually update the app as we discover new tuning information. Anytime a new cylinder or part is introduced, all of the testing we do at the shop will flow directly to Jetmax. Jetmax will also calculate the relative horsepower for that atmospheric condition. The relative horsepower percentage is helpful information to have when selecting your gear ratio. In certain situations you can benefit from increasing your gear ratio when HP is low & decreasing your gear ratio when HP is high. Whether you're competing at the track or fine-tuning your kart for practice, Jetmax gives you accurate, reliable recommendations so you can focus on performance. Features: - Jetting calculator for Rotax engines - Calculates relative horsepower - Includes an interactive gearing chart Engineered by racers, for racers — Fox + Son Jetmax App delivers the tools you need to stay competitive on race day. *You must have a valid subscription in order to use this app.
