MySpotter® Racing App* MySpotter® is a live timing app that provides you real time information, not only of your laptimes, but your direct competitor´s, while you are on track racing. Helps you improve at each single lap and strategically plan your race The app can be used on motor racing (go-kart, cars, motorbikes, etc) *MySpotter® will provide* • Visualization of your lap times, real time • Analyse your track performance, comparing your last lap with your best lap • Compare the lap time delta between you and your direct competition • Remotely connect on races and also support racers/teams as a spotter, on sprint or endurance races *MODO RACE* 01 - Current position 02 - Elapsed lap time (real time) 03 - Laps completed 04 - Upward arrow: your current lap time is worse than your previous lap. Downward arrow: your current lap time is better than your previous lap 05 - Current lap time 06 - Variance between your current lap time and your best lap time 07 - Time difference between you and the kart ahead (does not consider backmarkers) 08 - Kart ahead number 09 - Indicative arrows. Red arrows: your direct competitor (ahead or behind you) was quicker than you, on the last lap. Green arrows: you were quicker than your direct competitor (ahead or behind you), on the last lap 10 - Your kart number 11 - Time difference between you and the kart behind (does not consider backmarkers) 12 - Kart behind number *MODO QUALIFY* 01 - Current grid position according to your best lap 02 - Qualify session time elapsed 03 - Laps completed 04 - Current lap time 05 - Variance between your best lap time and the pole position lap time O MySpotter® é compatível com pistas que utilizam os systemas MyLaps® e Racemonitor® Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://myspotter.app/mys_termos.pdf For more information reach out to us on Facebook, Instagram or e-mail suport@myspotter.app https://www.facebook.com/Myspotterracing/ https://www.instagram.com/myspotter_racing/
RaceLineCalc
Read full descriptionHide full description
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.

Verdict
The clearest difference is update cadence: RaceLineCalc at every 3 days against MySpotter's every 3 weeks. On price, ads, in-app purchases and device support there is nothing between them.
