onTrackTools vs PB Buddy

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.

PB Buddy is a lap timer app for HPDE and time trials. It offers an easy-to-use, minimalist interface that allows you to focus on what matters most. The user experience has been crafted to work well for drivers of all skill levels, from beginners to seasoned racers. The app has been tested at numerous Time Trials and helped set over a dozen class records across the US. Key features: 1. Easy to set up. The app walks you through the setup and explains how to use it. You don’t need to be an IT professional just to see your lap times. 2. Easy to use. Once the initial setup is complete, simply open the app, press the button to start recording, confirm the track, and you're ready to go! 3. Quickly get feedback on your current lap. Thanks to big, bright visual elements and fun, vibrant colors, you can easily see if you’re on a good lap or lost too much time to set a new personal best (PB). Forget counting the number of tiny LEDs! 4. Fast and targeted feedback. It’s too late to review data in the paddock if you only have one session in the morning when the conditions are best! With PB Buddy, you get instant feedback for each sector of the track (or even per corner!), so you can turn even a bad lap into an opportunity to try something new in that tricky corner you’re struggling with, and find another tenth of a second for your next hot lap. 5. YOU own your data. Export data for each session in CSV format compatible with many existing third-party apps, or export every byte recorded by the app in a developer-friendly format if you enjoy tinkering with data. 6. Supports most race tracks in the US, with more tracks and configurations coming soon. 7. Supports the built-in GPS receiver, but works best with third-party Bluetooth-enabled GPS devices.
