LapTrace vs BoxBox

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.

BoxBox turns your iPhone and Apple Watch into a lap timer, telemetry system and live pit wall for karting, formula and GT racing. Drop your phone in the car, strap on your watch, or pair a RaceBox over Bluetooth for 25 Hz GPS: BoxBox times every lap automatically, shows your live delta, and speaks your gaps so your eyes stay on the track. TIME: automatic lap detection on any circuit, live delta to your best, sector timing. Tracks are created on the go, no library to download. REVIEW: every session saved with full telemetry. Replay your line on the map coloured by speed, braking in red, lap against lap, and find the corners where the time is hiding. SHARE: go live so friends, coach or team can watch your session in real time, lap by lap, with your position on the track map. APPLE WATCH: start a session from your wrist, with or without the phone in the car. Last lap, best, live delta and your heart rate on the watch. One tap for a good lap, two for a slow one. Start on the phone and the watch mirrors it, or the other way round. APPLE HEALTH: turn it on and your heart rate and active energy from Apple Health are kept with every session, so you can see how hard each stint really was. BOXBOX PRO: optional monthly subscription that unlocks your complete session history and everything we ship next. Payment is charged to your Apple Account; the subscription auto-renews monthly unless cancelled at least 24 hours before the end of the period.
