onTrackTools 1.5.1 finds and repairs damaged track configurations and fixes bugs in the Garage, average lap speed and the Mac configuration editor. New to 1.5? Everything from our biggest update yet follows below. 1.5.1 IMPROVEMENTS • Damaged track configurations: the Tracks Manager marks a configuration that needs repair. Repair fixes what it can, keeps your sectors, and reports anything left for you to fix. • An empty laps table now explains itself: a banner says why and offers Repair or Open Configuration Editor. • Configuration editor: Place Start Line and Reset Sectors on every device, and a clear error when a change can't be saved. • Batch Import (PRO) skips damaged configurations and flags the file; the single-file import warns about them. 1.5.1 FIXES • Garage: deleted setup elements no longer come back. • Garage: setups of a cloned configuration keep their front and rear variants, and elements swapped by 1.5.0 are corrected automatically. • Garage: corner weight can be entered in pounds. • Average lap speed uses the same lap length for every session on a configuration, and shows "—" until the configuration has a lap length or a reference lap. • Repairing configurations no longer stops at the first problem or deletes your sectors on a built-in track's default configuration. • Refreshing the track library no longer resets a damaged default configuration. • Mac: sector separators can be dragged in the configuration editor again. onTrackTools 1.5 is our biggest update yet. ANALYSIS DASHBOARD (PRO) • Build your own analysis screens from seven widgets: line chart, XY scatter (G-G diagram, friction circle), track map, histogram, statistics, heatmap and frequency. • Season-wide statistics: compare every session on the same track, filtered by date, car, setup, layout or driver. • Dashboards follow the laps you select, share the cursor with the charts, map and video, and sync through iCloud. Open several at once on Mac and Apple Vision Pro. DRIVERS & SESSION TYPES • Drivers (PRO): keep a profile for each driver and attribute laps to them, stint by stint. The laps table shows who drove each lap. • Session types on every plan: Track Day, HPDE, Coaching, Qualifying, Race, Endurance, Time Attack, Autocross, Hillclimb, Drift and more, or your own. • Filter and search sessions by type and driver; Spotlight finds them too. "Manage with AI" in the Garage now handles drivers. BATCH IMPORT (PRO) • Import a whole folder of VBO and LD files in one go on Mac, iPad and Apple Vision Pro. Track, date, vehicle, drivers and session type are worked out from each file and can be reviewed before importing. IMPROVEMENTS • Faster start-up and less work during iCloud sync. • iPhone, iPad and Vision Pro: Settings ▸ Storage cleans up copies of imported files no longer needed. PLANS • Every feature is unlocked for your first week, with nothing to sign up for. • Three plans: Free, onTrackTools and onTrackTools PRO, monthly, yearly or one-time. If you already own onTrackTools, a discounted upgrade to PRO lifetime is available. • After the week, the free plan keeps your three most recent sessions open. Nothing is ever deleted: older sessions stay in your library and unlock again when you subscribe or purchase. 1.5 FIXES • Fixed a crash during iCloud sync on iPhone, iPad and Apple Vision Pro. • Fixed a crash at launch after a long time without opening the app. • Switching sessions with the details open no longer carries the previous session's values over. • Video playback no longer gets stuck after panning a chart. • Mac, UI: sector deltas now follow Dark Mode right away. ...and many other improvements! Please update onTrackTools on all your devices: earlier versions cannot read data saved by 1.5.

MATH CHANNELS V2 • Lap, selection, and session statistics right in your expressions: min, max, average, standard deviation, normalization, and z-score. • Use your car's configuration and setup values (mass, tire pressures, …) as channel inputs — with 20 new units, including force in Newtons or pound-force. • Compare laps: bind an input to the fastest lap, the 2nd fastest, or a specific lap, and build channels like speed − speed_ref. • Math channels can reference other math channels, and the time delta is now available as an input. • The signal browser is organized by source: telemetry, vehicle configuration, vehicle setup, and math channels. • "Create with AI" understands all of it, applies unit conversions exactly, and remembers the signal choices you already made. LAP LENGTH & AVERAGE SPEED • Track configurations carry a lap length — from the built-in track library or measured from your reference lap. • New average-speed column in the laps table, and best-lap average speed in the session list. IMPROVEMENTS & FIXES • Spotlight search now works from macOS 15, iOS/iPadOS 18, and visionOS 2 — and opening a result takes you to the exact session, note, car, or setup. • Toolbar labels: native Finder-style labels on macOS, no more clipped labels on iPad. • Deleted items no longer appear in track filters and pickers. • Fixed a Math Channels crash on macOS when opening the Expression Reference. • Assistant fixes: garage changes can no longer be misread as creating a new car, and notes are always filed under real categories. • Fixed the Details button on iPhone becoming unresponsive after viewing lap analysis. This version updates the database format — please update onTrackTools on all your devices together. New to 1.4? Version 1.4.0 introduced on-device AI assistants for session notes, garage, and math channels, Siri & Spotlight integration, empty sessions with the Session Details view, and automatic weather.

AI assistance comes to your track days - powered by Apple Intelligence, running entirely on-device - plus a redesigned session workflow. AI ASSISTANTS • Session Notes: dictate your impressions right out of the car and the assistant turns them into structured session notes. • Garage - Manage with AI: update configurations and setups conversationally ("set the front tire pressures to 28 psi"), ask what you ran before, and confirm every change before it's applied. • Math Channels - Create with AI: describe the channel you want in plain language; the assistant builds the formula, maps the signals from your data, and shows a review before creating it. • Hands-free voice mode on every assistant, with spoken replies and motorsport vocabulary recognition. • Siri & Spotlight: open sessions, show setups, create sessions, and capture notes without opening the app. TRACK-DAY WORKFLOW • Create a session before the data exists: log vehicle, setup, conditions, and notes at the track, then attach telemetry and video later. • New Session Details view: manage videos, data files, track configuration, vehicle, and setup in one place - one flip away from the analysis view. • Redesigned session list: lap count, best lap time, and weather at a glance, with search and filtering. • Automatic weather: conditions are retrieved from Apple Weather for new sessions, and existing sessions are backfilled automatically. FIXES & REFINEMENTS • Garage editors polished on iPhone and Vision Pro, with clearer element labels for per-corner and per-axle values. • Improved window handling on Apple Vision Pro. • Many smaller stability and UI improvements across all platforms. AI features require a device that supports Apple Intelligence running iOS/iPadOS 26, macOS 26, or visionOS 26 or later. All AI processing happens on-device - your data never leaves your device.

Version 1.3.0 adds powerful new tools for deeper telemetry analysis. • Math Channels: Create reusable calculated traces from built-in or logged channels. Define expressions with unit-aware inputs, aliases, common math functions, derivative/integral support, live validation, signal browsing, and per-session input overrides. • Automatic Sector Detection: Generate sector layouts from lap telemetry using corners, braking zones, speed peaks, or equal-distance splits. Tune sensitivity, sector count, and advanced placement settings, then adjust the result on the map before applying. • Persistent Analysis State: Switch between sessions and comparisons without losing your place. Selected laps, chart traces, sector zoom, scrubber position, chart range, map view, and follow-car mode are restored per session set. • Faster, more reliable sync: Large telemetry data is now compressed to reduce storage use and improve iCloud sync reliability, especially for large imports. CloudKit and subscription status updates are also smoother. • Fixes and polish: Improved chart behavior while zooming and resizing, clearer warnings for incompatible comparisons, more reliable trace controls on iPhone, and many other improvements and fixes.

Version 1.2.1 adds major new features, plus performance and reliability improvements across the app. • Added a built-in library of 600+ track layouts, with automatic track detection during session import. • Added support for LD telemetry files, including sim-racing originated data files. • Improved chart and video scrubbing performance, especially on macOS. • Track manager now shows track previews.
