LapPulse Timer vs RaceLineCalc

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.

RaceLineCalc calculates a racing line from your own track image, map, plan, sketch, or satellite screenshot. Use the optimized racing line to improve your lap times. Use track analysis to study apex placement, cornering, braking points, speed, and lap time. Create a track project: • Import an image and calibrate it with a known real-world distance. • Trace the left and right track boundaries and place the start/finish reference. • Choose a point-based, car-based, or motorcycle-based model and a vehicle preset. • Run the calculation on your device. Review the result: • Calculated racing line and lap time. • Speed, longitudinal acceleration, lateral acceleration, and braking points. • Calculation stations, source boundaries, and generated track geometry. • Run history and comparison of compatible results on the same track. The point-based model quickly calculates a stable racing line. Car and motorcycle models add vehicle mass, power, grip, braking, dimensions, steering, and lean-related parameters. Presets cover karting, road cars, track cars, and motorcycles, while advanced controls allow deeper experiments. RaceLineCalc is local-first: the calculation runs on the device, and the core project flow does not require an account or upload your track project to a RaceLineCalc server. Model scope: RaceLineCalc calculates on a calibrated flat 2D track model. Elevation, banking, jumps, ruts, changing grip, weather, traffic, live surface conditions, and other real-world factors remain outside the current model. Always combine the calculation with real track knowledge and safe driving or riding practices. RaceLineCalc combines a racing line calculator, track analyzer, lap time calculator, and racing line optimizer in one local-first toolkit. As a practical race line calc, it uses calibrated track geometry and vehicle parameters to estimate the optimal line, speed profile, braking points, and lap time. Minimum-time trajectory optimization: RaceLineCalc solves a constrained minimum-time race trajectory problem on a calibrated flat 2D track. It combines track geometry with a point-based, car-based, or motorcycle-based model to calculate a minimum-time racing line, speed profile, braking points, longitudinal and lateral acceleration, and lap time. Use RaceLineCalc as a race trajectory optimizer, racing line calculator, lap time calculator, vehicle dynamics analysis tool, track analyzer, and trajectory planner. It supports image-based track analysis for karting circuits, indoor tracks, road courses, custom layouts, private test tracks, and local racing venues. The result is a time-optimized trajectory within the selected geometry, vehicle model, grip, power, braking, and configuration limits. Five physics models: point mass, Car V1 and V2, and Moto V1 and V2. Explore additional model-specific overlays and legends, then compare saved runs on the same track. Project run history is preserved after track edits, and results from an older track version are marked.
