RKCC currently supports Apex Live Timing only. Additional timing providers are planned for the future.
RKCC
Which kart tracks are currently supported?

At launch, RKCC includes 50 verified Apex Live Timing kart tracks.

RKCC currently supports kart tracks that use Apex Live Timing and have public live timing enabled.

Why is no live status shown for Alpha tracks?

Tracks marked โ€œ(Alpha)โ€ are checked only when you select the individual track. This avoids sending too many status requests at the same time. Their live status is therefore not loaded automatically in the general track list.

Why does my kart track not appear in the app?

A track only appears if it has been added to RKCCโ€™s supported track database and if public Apex Live Timing is available.

Some tracks may use Apex Timing internally but do not have public live timing enabled. In that case, RKCC cannot connect to live race data.

My track uses Apex Timing. Why does RKCC still not work there?

Using Apex Timing does not automatically mean that public Apex Live Timing is available. Some tracks may not have live timing enabled, may use a private configuration, or may not include live timing in their current Apex package.

Example: A track can use Apex Timing for internal timing, but if the public live timing page is not active, RKCC cannot access live race data.

Can I suggest a kart track?

Yes. If you know a kart track that offers public Apex Live Timing, you can suggest it for inclusion.

Please provide:

  • Track name
  • Country
  • City or region
  • Apex Live Timing URL
  • Official website, if available
Will more tracks be added?

Yes. More supported kart tracks will be added over time, especially if users suggest tracks with public Apex Live Timing.

Will RKCC support timing providers other than Apex?

Yes, support for additional timing providers is planned for the future. The first release focuses on Apex Live Timing to keep the app stable and reliable.

Does RKCC work on every kart track?

No. RKCC only works on supported tracks with compatible live timing data. If a track is not listed or does not provide public live timing, RKCC cannot provide live race information for that track.

Why are some features free and others premium?

The free version lets you test whether RKCC works on your track. Premium features unlock the full race crew chief experience, including position calls, live gaps, rival watch, race progress and the advanced dashboard.

Roadmap / Future Features Future ideas Feature suggestions welcome

Future Features / Roadmap

RKCC is still at the beginning. The first release focuses on stable Apex Live Timing support and a reliable race dashboard. More features are planned for future versions.

More timing providers

Support for additional timing providers is planned. The first release focuses on Apex Live Timing to keep the app stable and reliable.

More kart tracks

More supported kart tracks will be added over time. Users can suggest tracks if public live timing is available.

Custom voices

Future versions may offer more voice options, including custom crew chief voices and different announcement styles.

Talk to your AI Race Engineer

A future AI Race Engineer mode could allow you to ask questions during or after a session, such as "Who is catching me?", "Where can I improve?" or "What is my gap to P3?"

Voice messages to rivals

In the future, drivers using RKCC could send short voice messages to rivals or teammates during a session, if both drivers use the app and have enabled this feature.

Team / Club mode

Team and club features could allow race organizers, friends or karting clubs to follow multiple drivers and share race information.

Championship mode

Future versions may support championship standings, points systems and live position forecasts based on the current race result.

AI race summaries

After a race, RKCC could generate an AI-powered summary with key moments, position changes, best laps and tactical insights.

Personalized Rival Watch

Rival Watch could become more advanced, allowing users to save favorite rivals and receive smarter updates based on race context.

Track-specific profiles

Track-specific profiles could store preferred drivers, favorite kart centers, voice settings and dashboard preferences per track.

Cloud sync

Future versions may sync settings, favorite tracks and premium access across devices.

Wearables / headset optimization

RKCC may later be optimized for helmet audio, wireless earbuds, wearables or other hands-free race setups.

Race strategy assistant

Future versions could include strategy hints, such as when to defend, when to push, whether a rival is gaining, or whether a penalty changes your position.

Practice coaching

Practice mode could focus on consistency, lap time trends and improvement hints instead of race position.

Kart history / performance notes

Users could save notes about rental karts, such as handling, braking, acceleration or personal bests with a specific kart.

These ideas are not guaranteed features. They are part of the long-term vision for RKCC and may depend on technical feasibility, timing provider access, user feedback and development priorities.

Some advanced future features may become Premium or Pro features.
