onTrackTools vs Kerbz Laps

onTrackTools brings professional-grade motorsport telemetry analysis to your iPhone, iPad, Mac, and Apple Vision Pro. Whether you're refining your driving skills, comparing laps, or validating car setup changes, onTrackTools turns raw track-day data, video, and logged signals into clear, actionable insight. Key Features • Import & Analyze Telemetry: Load VBO and LD session files, then explore speed, acceleration, lateral/longitudinal Gs, GPS traces, and any other logged channel. • Analysis Dashboard (PRO): Build your own analysis screens from line charts, XY scatter plots, track maps, histograms, heatmaps, frequency plots, and statistics. Compare every session on a track, filtered by car, setup, or driver. • Drivers (PRO): Keep a profile for each driver, attribute laps stint by stint, and see who drove each lap. • Batch Import (PRO): Import a whole folder of sessions in one go on Mac, iPad, and Apple Vision Pro, with track, date, vehicle, and drivers worked out from each file. • Session Types: Tag sessions as Track Day, HPDE, Race, Time Attack, Autocross, and more, then filter and search by type or driver. • AI Assistants (Apple Intelligence): Dictate your impressions right out of the car and get structured session notes, create math channels by describing them in plain language, and manage your garage and drivers conversationally, every change echoed back for confirmation. Hands-free voice mode on every assistant. All processing happens on-device: your data never leaves your device. • Siri & Spotlight: Open sessions, show setups, create sessions, and capture notes without opening the app. • Math Channels: Create reusable calculated traces with formulas, unit-aware inputs, derivatives, integrals, and common math functions. • Built-In Track Library: 600+ track layouts, with automatic track and direction detection during import. • Automatic Sector Detection: Generate sector splits from corners, braking zones, speed peaks, or equal distances, then fine-tune them on the track map. • Automatic Weather: Conditions for every session are retrieved from Apple Weather. • Plan Your Track Day: Create a session before the data exists, log vehicle, setup, conditions, and notes at the track, then attach telemetry and video later. • Synchronized Video Overlay: Pair any video file, or one from your Photos Library, with your data. Not tied to any proprietary logger or camera. • Side-by-Side Lap Comparison: Compare laps aligned by time or distance and see where you gain or lose time. • Interactive Track Maps: GPS traces, car position, and sectors on the circuit map. Tap a sector to zoom straight to it. • Custom Tracks & Open Courses: Define your own tracks, sectors, or separate start and finish lines for hillclimbs, rally stages, and more. • Lap & Sector Tables: Best sectors highlighted and your theoretical ideal lap. • Persistent Analysis State: Laps, traces, zoom, and map view are restored per session set. • Garage Management: Vehicles, configurations, and setup changes for every session. • iCloud Sync: Sessions, tracks, garage, drivers, dashboards, videos, and math channels sync across all your devices. Plans Every feature is free for your first week, with nothing to sign up for. After that, the free plan keeps your three most recent sessions open; onTrackTools unlocks unlimited sessions, and onTrackTools PRO adds the dashboard, drivers, and batch import. Both are available monthly, yearly, or as a one-time purchase. Nothing you create is ever deleted. AI features require a device that supports Apple Intelligence running iOS/iPadOS 26, macOS 26, or visionOS 26 or later. Everything else works on every supported device. Whether you're chasing personal bests, fine-tuning driving technique, or testing car upgrades, onTrackTools is designed to help you get the most out of every lap.

Live coaching and timing. Kerbz Laps turns your device into a GPS lap timer for track days: it times every lap from the start/finish line, shows you as you drive whether you're ahead of your best, reads out your lap times, coaches you from your own best laps, and keeps the whole session for when you're back in the paddock. ON TRACK • Lap times from the GPS, timed where you crossed the line, not when the next reading came in • A live gap to your best lap at this track, in this car and these conditions, with your predicted lap time and your speed against your best • The screen fills green when you're ahead and red when you're behind, big enough to read at a glance • A new best lap lights up the screen, and every lap time is read out loud, through your device or your car's speakers • Timing starts when you drive off and asks to stop when you pull in • On your out lap, how far you have left to the start/finish line VOICE COACHING (with a free Kerbz account) • Before a turn where you have time to find, a tip from your own best lap there: "Turn 2: carry 4 mph more out of the turn, like your best" • A word when you match or beat your best through a turn, or set a new best lap • It waits until it has enough laps to go on, and never asks for more than you've already done AFTER THE SESSION • Your best lap, your optimal lap (your best through each part of the track, added up), your average, your top speed and how consistent you were • Turn by turn: your time, and your speed into the turn, mid-turn and out of it • Where the time is: the turns with the most to gain, and what your best lap did differently there • Where you braked, turned in and got back on the power, lap against lap, next to your best • Film the road with your device's camera or a GoPro, then watch it back with your lap data over the video, two laps side by side YOUR KERBZ LOGBOOK • Save your sessions to your Kerbz logbook, with the event, who ran it and your car • Registered for the event on Kerbz? The day is already in your logbook • Put your best lap on the track's leaderboard, where it goes up once its video is added MADE FOR THE TRACK • Works with no signal: tracks and your cars are kept on your device, and your sessions upload when you're back online • Your cars come from your Kerbz garage • Needs a device with built-in GPS Kerbz Laps is for closed race tracks only. Never use it on public roads. Set everything up before you drive, mount your device firmly, and don't touch it while the car is moving.
