LapPulse is the ultimate lap timer for kart drivers — precision telemetry in your pocket. REAL-TIME LAP TIMING Connect your RaceBox Mini via Bluetooth for 25Hz GPS-based lap detection with automatic start/finish line recognition. See your current lap, best lap, and live delta in real time on a heads-up display designed for the track. 3 HUD LAYOUTS Choose from Neon Grid, Racing Cockpit, or Clean Brutalist — each available in landscape and portrait orientation. Mount your phone on the wheel or dash and get the data you need at a glance. LAP COMPARISON Compare any two laps side by side with synchronized speed and delta charts. Scrub through the data and see cursor positions move on the track map in real time. Find where you're gaining and losing time. SPEED ANALYSIS Color-coded speed heatmaps overlay your racing line on a satellite map. Instantly see braking zones, corner speeds, and acceleration points. TRACK MANAGEMENT Create and manage your favorite tracks with a guided editor. Set start/finish lines and sector boundaries with precision using draggable pins and visual trigger zones. PERSONAL BESTS Track your PB progression across sessions for every track. See your improvement over time and celebrate new records. SESSION HISTORY Every session is saved with full telemetry data, weather conditions, and tags. Filter, search, and review your driving history. SHARE & COMPARE Export sessions as .lappulse files to share with teammates, or export CSV for external analysis tools. WORKS OFFLINE All data is stored locally on your device. No account required, no cloud dependency. Your data stays yours. REQUIRES: RaceBox Mini, Mini S, or Micro GPS device for live recording. Demo mode available for testing without hardware. BUILD YOUR OWN HUD Every driver reads a different number first. Drag widgets onto a snap grid and put yours where your eyes already go — current lap, best lap, live delta, predicted lap, speed, sector lights and more. Portrait and landscape get their own layouts. The stop button always stays put, so you can never lose it mid-session. ## Version history (last 4 releases) ### 1.4.4 — 2026-08-01 BUILD YOUR OWN HUD Stop settling for a fixed layout. Drag widgets onto a snap grid and put every number exactly where your eyes already go. • Ten widgets: current lap, best lap, last lap, lap number, live delta, delta bar, predicted lap, speed, sector lights and session time • Separate layouts for portrait and landscape, because they are not the same problem • Drag to move, drag the corner to resize, or use the size buttons • Start from the default layout and change one card, or rebuild it from scratch NEW: PREDICTED LAP TIME Your best lap plus the delta you are carrying right now. It answers "am I on for a PB?" without doing the maths at 90 kph. NEW: SESSION TIME Total time recording, so you can pace a booked track slot. FAR MORE ACCURATE LIVE DELTA The delta used to line laps up by integrating speed, which drifts. Error grew across the lap and snapped back at the start/finish line. It now matches your GPS position against the best lap's actual path, the same approach VBOX and AiM use. Measured against ground truth: average error dropped from 96 ms to 0 ms, worst case from 269 ms to 26 ms, and the 0.21 s jump at the line is gone. Laps are also timed at the exact moment your path crossed the line, not at whichever GPS tick noticed. ACCOUNT DELETION Delete your account from inside the app. Tracks you published to the Workshop stay available to other drivers, and their lap times on them survive. FIXES • Fixed crashes on the session detail and comparison screens • Patched security advisories in bundled dependencies ### 1.4.1 — 2026-07-25 • Personal bests now stay with the correct track layout — layouts sharing a name at different circuits no longer share a PB • Browse community tracks from the Add Track screen, with offline detection • "Venue" is now called "Track" throughout the app • New tracks require at least three sectors for meaningful sector deltas • Your profile card now shows a public/private badge • Speed Delta removed from the HUD to keep 25 Hz timing smooth ### 1.3.1 — 2026-04-02 v1.3.1 — Major Update - Phone GPS mode — no hardware needed to start recording - Track Workshop — browse, download, and publish community tracks - Sign In with Apple & Google - Post-session summary with stats and top laps - 17 achievements across 6 categories - Lap replay animation with speed trail - Session photos, GPX export, share cards - Performance trends charts - Track search, filters, and sorting - Auto leaderboard submission ### 1.3.0 — 2026-03-19 No release notes. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
