UChrono

U Chrono is much more than a chronometer — it's a comprehensive tool designed for racing enthusiasts who strive to improve their performance on the track, lap after lap.

With an intuitive and user-friendly interface, U Chrono allows you to manually record lap and split times in real time — ideal for sessions where a coach, teammate, or assistant is tracking performance from the sidelines. Practice sessions are saved locally, enabling you to review and compare results even without an internet connection.

The app includes a complete kart setup configuration module, allowing you to adjust essential parameters such as tire pressure, apertures, and carburetion, as well as manage installed engines and their maintenance history. Each driver can have a personalized profile, including kart number and custom setup, making it perfect for individuals and teams alike.

At the end of each practice session, you can export results in PDF format, making it easy to share technical reports or feedback with coaches, engineers, or teammates.

U Chrono is the perfect solution for:

Professional drivers
Karting schools
Racing teams
Coaches
Amateur drivers
