iRacing, a premier platform for high-speed sim racing, can be improved enormously by selecting from a variety of free apps. These apps, ranging from software that adds cosmetic changes to practical racing engineering tools, are designed to take some of the mental load away from your virtual racing experience. Crew Chief is such a good example of this (and it’ll be on the list, naturally!)

Trophi.ai is a new AI coaching tool designed for gaming, specifically sim racing (of course!). It offers an all-in-one app experience to help gamers reach top performance with just a few just minutes spent a day. Key features include:

  1. Live AI Coaching and Interactive Lap Guides: These provide real-time guidance and subsequent feedback to improve pace and performance while practising.
  2. Post Session AI Feedback and Mistake Analyzer: The app gives detailed feedback post-race, focusing on techniques and highlighting mistakes with an improvement plan.
  3. Custom Programs and Courses: Trophi.ai’s AI selects interactive learning programs tailored to the user’s needs, ensuring effective and rapid skill development.
  4. Interactive Mechanic Training and AI Post Match Analysis (Rocket League): This aspect of the app focuses on building motor skills and providing comprehensive reports post-match to guide improvement.

The tool, built on years of coaching experience, promises to make learning complex concepts and mechanics fun, simple, and easy. It’s designed to be user-friendly, with a setup time of just 60 seconds, making it accessible for gamers looking to enhance their skills efficiently.

Trading Paints

A step up from iRacing’s in-engine paint system, Trading Paints (read our how-to here) allows for a more personalized experience by enabling users to download and apply custom paint schemes to their cars.

VRS Telemetry Logger

This tool provides data from your driving in each session, working both online and offline. It’s perfect for comparing performance across different cars and refining your driving skills. The main caveat is unlike Trophi.ai, VRS doesn’t give you actionable technique changes you have to be able to interpret this data yourself.

The data itself though s very much like the data you’d be able to download from a real racing car, I use AIM systems and their analysis software, Race Studio 2, looks very familiar:

Crew Chief

Crew Chief (read our comprehensive guide here) Acts as your virtual crew chief, providing comprehensive real-time session data and feedback, essential for all sim racers. Crew Chief is quite simply a must-have free iRacing app. Even if for one reason: it manages your fuel levels for you in an endurance race:

Improves upon iRacing’s default “black box” by providing more on-screen information at once, like iRating of rivals and session data.

Soundshift helps with gear shifting by playing a beep at the optimal upshift point for each car. It can be tailored to specific gear ratios and engine tunes. F1 drivers still use this technology the extract every last ounce of performance from their car.


SIMRacingApps offers a customizable HUD that can be displayed on secondary devices like tablets or smartphones, providing essential race data conveniently.
