Vetkuro vs onTrackTools

Vetkuro is lap timer and track day telemetry app for drivers who want more than just a time. Sector splits, telemetry overlays, GPS racing line and OBD-II channel logging - all working from the phone in your pocket, with the gear you already own. Whether you run track days at your local circuit, compete in karting, autocross or time attack, or just want to understand why your lap times aren't improving, Vetkuro gives you the data layer that makes the difference. GPS LAP TIMER & SECTOR TIMES Vetkuro starts timing the moment you cross the start/finish line. Each lap is split into sectors so you can see not just your total time but where you are gaining and losing against your best. Compare sector-by-sector across unlimited laps and sessions. [Assumption - verify lap comparison limit] TELEMETRY THAT MAKES SENSE Unlike basic lap timer apps that give you a number and nothing else, Vetkuro logs full telemetry channels: speed, braking, throttle, G-force and heart rate. Overlay them lap-over-lap. Find your braking point. Find your exit speed. Find the tenth you have been leaving on the table. GPS RACING LINE Your GPS racing line is plotted on a track map after every session. See where you braked too early, where you ran wide on exit, where your line through sector 2 cost you. Data, not guesswork. OBD-II ENGINE DATA Connect a compatible OBD-II adapter and Vetkuro logs engine channels alongside your GPS data. Supported adapters: Carista, vLinker MC+, NEXAS NexLink. HEART RATE MONITORING Pair any Bluetooth LE heart-rate strap or your Apple Watch and your BPM is recorded alongside speed, GPS and OBD channels. Track your physical response to on-track stress. HARDWARE SUPPORT Vetkuro is designed to work without any add-ons, your phone's GPS is enough to get started. When you want higher accuracy, pair it with supported external hardware. BUILT FOR EVERY TRACK DISCIPLINE Track days. Karting. Autocross. Time attack. Club racing. Vetkuro works at any circuit where you can define a start/finish line. TURN DATA INTO SPEED Download Vetkuro and arrive at your next track day with a data plan for every sector.

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. • 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 conversationally, every change echoed back for confirmation before it's applied. Hands-free voice mode with spoken replies 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 from your data using formulas, unit-aware inputs, aliases, derivatives, integrals, and common math functions. Chart them alongside built-in and logged channels. • Built-In Track Library: Start faster with a built-in library of 600+ track layouts, with automatic track detection during import. • Automatic Sector Detection: Generate sector splits from a selected lap using corners, braking zones, speed peaks, or equal-distance algorithms, then fine-tune and apply them on the track map. • Automatic Weather: Conditions for every session are retrieved automatically from Apple Weather and shown alongside your laps. • 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 supported video files - or videos stored in your Photos Library - with your data. Not tied to any proprietary data logger or camera. Watch delta times update frame-by-frame as you scrub through laps. • Side-by-Side Lap Comparison: Compare two laps in detail, aligned by time or distance on track, and instantly see where you gain or lose time. • Interactive Track Maps: Visualize GPS traces, car position, and custom sector splits directly on the circuit map. Tap any sector on the map or chart to zoom straight to it. • Custom Tracks, Sectors & Open Courses: Define your own track, start/finish line, sector splits, or separate start and finish lines for autocross courses, hillclimbs, rally stages, and more. • Lap & Sector Time Tables: Break down performance with detailed tables, highlight best sectors, and calculate your theoretical ideal lap. • Sessions at a Glance: Every session row shows lap count, best lap time, and weather, with search and filtering to find any session fast. • Persistent Analysis State: Switch between sessions and comparisons without losing your working context - selected laps, traces, chart zoom, map view, scrubber position, sector zoom, and follow-car mode are restored per session set. • Garage, Vehicle & Setup Management: Track your car's history. Create vehicles, build configurations, and log setup changes for every session. • iCloud Sync: Your sessions, tracks, garage, videos, and math channels sync automatically across all your devices via iCloud. 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.
