ApexLap vs LapTrace

Your phone becomes a professional data-logger. ApexLap times every lap automatically the moment you cross the start line — reliably, every single time. Built for track days: cars, motorcycles and karting. No manual needed, readable in full sun through a visor, usable with gloves. RELIABLE LAP TIMING — FREE FOREVER • Automatic start/finish detection with millisecond interpolation • Every lap is saved the instant it completes — a crash or dead battery never loses your data • 500+ circuits built in worldwide, karting included — no second app to buy • Create your own start line for any track in seconds • Sessions per circuit, laps sorted by best time, best lap and theoretical best • Your recorded laps, sessions and history are never locked behind a paywall APEX PRO — THE FULL DATA-LOGGER • Video overlay export that actually works: lap time, speed, G-force and track map burned into your footage, fast and reliable • Full telemetry: speed traces, G-forces, auto sectors, live delta vs your best lap • Lap comparison: overlay two laps and see exactly where the time is • External 10 Hz GPS receivers (RaceBox, Garmin GLO, Dual…) and OBD-II engine data • Progression analysis per circuit, session after session • Setup sheets: tires, pressures and settings logged with each session • CSV export, unlimited custom circuits Try Apex Pro free for 7 days with the yearly plan. Monthly and one-time lifetime options available. Your location data stays on your device. No account, no tracking.

Turn your iPhone into a local-first telemetry recorder and video companion for karting, cycling, and outdoor activities. RECORD THE SESSION • Start a karting, road-cycling, or outdoor session in seconds. • Capture timestamped location and motion telemetry with source and quality information. • Follow recording duration, current speed, quality, and active Apple-device sources with a local Live Activity. • Road cycling includes moving-time auto-pause, with a per-ride option to turn it off; raw telemetry and elapsed time continue. • Open LapTrace on a paired Apple Watch to add a separate Watch location stream to the active iPhone recording. • Keep the original sensor log while LapTrace calculates useful derived values. UNDERSTAND THE DRIVE • Review your route, speed, distance, and telemetry quality. • Optionally download nearby public kart-track data from OpenStreetMap after a clear permission prompt; normalized track data is cached locally for offline use. • When route evidence is strong, review the matched track layout, edit an unsaved start/finish suggestion, and compare an additional track-constrained route. • Set a non-destructive driving range to exclude setup or shutdown time from kart review and flat exports while preserving the complete raw recording. • When Watch data is available, compare iPhone, Apple Watch, and combined routes, observed rates, distance, gaps, and source timing. • See current, previous, and best lap times. • Compare lap deltas and inspect a speed trace without a wall of engineering data. • Configure a directed start/finish line and reusable track when needed. SYNC ACTION-CAMERA FOOTAGE • Import video from Photos or Files. • Align footage and telemetry with dependable coarse and fine offset controls. • Set video and telemetry in/out points. • Preview speed and lap values at the selected moment. CREATE A SHAREABLE VIDEO • Choose from reusable overlay presets. • Adjust overlay position, scale, and opacity. • Render the overlay with AVFoundation, then save or share the finished video. OWN YOUR DATA • Export CSV, JSON, GPX, FIT, or a documented LapTrace session archive where appropriate. • No account, LapTrace backend, analytics, tracking, or automatic upload. • Telemetry, imported media, projects, and exports remain local to your devices until you explicitly save or share them. LapTrace clearly labels each session's telemetry source and quality. FIT exports include timestamped position, altitude, speed, distance, lap, session, and activity records.
