LapPulse Timer vs QUAD

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.

A GPS lap timer that works anywhere on Earth, and an integrated vehicle-dynamics G-force meter. Using nothing but your phone's sensors and GPS, it times laps and sectors while showing four-wheel weight transfer, G-forces and chassis attitude in real time. No extra sensors. ■ GPS lap timer Circuits, of course — but you can set a course anywhere in the world. Long-press the map to place start, finish and sector lines, and every crossing splits a lap and a sector automatically. Best lap, last lap and every sector time stay on the main screen, so you can see where you are finding time while you drive. Closed circuits and open point-to-point courses are both supported, so rally and hill-climb stages work too. Save as many courses as you like, set which direction counts as a crossing, and add as many sectors as you need. With no course set, the LAP button still times from where you stand. ■ One integrated meter Four-wheel load, the G-G diagram, yaw rate and roll/pitch on a single screen, right alongside the lap display. Everything you need while driving, in one place. ■ Four-wheel load monitoring Weight transfer is computed from G-forces and your vehicle specs, then shown at each corner as colour and numbers, so you can see whether you are using all of the tyre. Load falling shifts blue, load building shifts red. Delta/absolute and %/kgf are both switchable. ■ G-G diagram Lateral against longitudinal G, with the trail you actually drove and the envelope of the limit you reached. The envelope is where your car's grip runs out, drawn for you. ■ Understeer and oversteer alerts Measured yaw rate is compared against the theoretical neutral-steer reference to catch sharp yaw-rate changes in the transient, and the app calls them out by voice and colour. The axle that is losing cornering force is boxed, so you can tell instantly which end is going. Tune it with a scene (circuit / winding road) × sensitivity profile. ■ Data logger and viewer Record a session and review times, racing line and vehicle data afterwards. A track map coloured by speed, time-series charts of G, yaw rate and attitude, and the G-G diagram all follow one playhead. Understeer and oversteer segments are marked on the charts. Export to CSV to analyse the data in external tools. ■ Customisation Theme (dark / light) and accent colour, which channels appear in the readout column, the range of each meter, load display units, render rate and more. ■ Three steps to start 1. Enter your vehicle info (weight, CG height, wheelbase, track, weight distribution). It works on the defaults, but the more accurate you are, the closer the load readout gets to your real car. 2. Mount the phone rigidly, screen upright. 3. Run calibration once before you drive. No sensors handy? Settings has a "Play demo" mode that replays real recorded track data through every feature. ■ About the in-app purchase Lap timing, the data logger and viewer, understeer/oversteer alerts and UI customisation are Premium features, unlocked with a single payment. There is no subscription and nothing auto-renews. ■ Please read This app is a simulated monitor that estimates and displays vehicle attitude, load, G-forces and understeer/oversteer tendency from phone sensors and GPS. It is not a certified measuring instrument or a safety device. All values shown are approximate and are not guaranteed to be accurate real-world measurements. Load is not a load-cell reading; it is a computed estimate. Timing accuracy depends on your device's. This app is intended for competition use in closed environments such as race circuits. Watching the screen while driving is distracted driving and is illegal and punishable under applicable traffic laws. Never watch the screen while driving on public roads. If you use it on public roads you must comply with all applicable laws and do so entirely at your own risk.
