DashFacer vs RaceLineCalc

DashFacer transforms your iPhone into a live racing dashboard, built for real drivers on real tracks. Mount it to your steering wheel and experience real-time performance insights while you race. DashFacer connects to live timing systems across licensed tracks, delivering instant lap data, sector performance, and live position updates — right where you need them most. Whether you're chasing personal bests or battling for position, DashFacer keeps you informed and focused with live data and intelligent voice feedback. Features: Real-Time Telemetry - live lap time, position, sector deltas, and gap analysis — updated while you drive. Sector Delta - See your gain or loss in each sector — get performance feedback before the lap is even finished. Multi-Class Position - See your real-time ranking not only overall, but also within your class. Whether you’re racing amateurs, or pro drivers, you always know your position against the right competitors. Voice Feedback - hear your latest lap time or performance changes without taking your eyes off the track. Steering Wheel Mount Friendly - designed for visibility and clarity from your wheel or dashboard. Optimized Dark UI - high-contrast design for outdoor visibility and night racing. Free Plan & Upgrades: The free plan includes all data channels and voice feedback for the first 5 minutes of your session. After this, voice feedback is disabled and some data channels are limited. Full access requires an in-app purchase or subscription. By using this app, you agree to DashFacer's Terms of Use. https://dashfacer.com/terms/

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.
