onTrackTools vs Dexian Timer

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.

Dexian Timer is a professional lap timing and telemetry analysis tool designed exclusively for track day and karting enthusiasts. Fully compatible with the high-performance 25Hz Dexian D1 GPS, RaceChrono DIY protocol devices, and .VBO file imports, it delivers the ultimate smooth experience for lap timing and data review. KEY FEATURES: • High-Precision GPS Data: Supports external GPS receivers with up to a 25Hz update rate, completely eliminating the lag of built-in smartphone GPS. • Universal Video Auto-Sync (Patent Pending): A pioneering dynamic timestamp QR code solution that breaks device barriers, supporting ANY external camera or smartphone for video recording. Simply record the on-screen QR code before driving; upon import, the app visually scans it to achieve millisecond-perfect alignment between your video and telemetry data, completely eliminating tedious manual timeline adjustments. • Bluetooth OBD Telemetry: Support for connecting external Bluetooth OBD modules. Read real-time underlying vehicle performance data (such as Engine RPM and Throttle Position) perfectly synced with your GPS telemetry, making your data review and exported videos look like professional motorsport broadcasts. • Innovative Pit2Car Communication: Break the communication barrier between the car and the pit wall! Without needing any account registration, your pit crew or friends can use a web browser to send real-time commands (like "Box") directly to your live dashboard while you are driving. • Perfect Map Alignment in China: Automatically handles map coordinate conversions to completely eliminate the trajectory offset issues common in traditional apps. Your racing line aligns perfectly with the map. • Auto Lap Timing & Real-Time Delta: Intelligently detects your current track and automatically triggers timing when crossing the start/finish line. During your stint, it displays a precise, position-based real-time delta against your session's or day's best lap, letting you instantly know your current pace. • Session Analysis & Dual-Lap Comparison: A dedicated landscape analysis workspace seamlessly integrating map trajectories, telemetry graphs, and onboard videos. Features highly synchronized dual-video and data playback to compare two laps side-by-side, visually identifying fast and slow sectors to find exactly where to push harder. • Video Export with Data Overlay: Export your track highlight videos with professional telemetry HUDs with a single tap. Freely configure the overlay elements (speed, G-force friction circle, OBD data, etc.) to create highly personalized videos ready for easy sharing. • 1,000 Built-in Tracks: Pre-loaded with nearly 1,000 touring car and karting tracks worldwide. No manual start/finish line setup required—just arrive and race. POWERFUL COMPATIBILITY Supports any Bluetooth GPS receiver based on the RaceChrono BLE DIY protocol. Seamlessly imports and exports industry-standard .VBO files to perfectly integrate with your existing data ecosystem. IMPORTANT SAFETY DISCLAIMER Motorsport is inherently dangerous. This application is designed exclusively for use on closed-circuit tracks and professional racing facilities. DO NOT use this app on public roads. The data is for reference only. Always prioritize safe driving.
