onTrackTools vs StopWatch For Multiple Cars

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.
