CircuitStorm is lap timer, data logger, and driving analysis tool designed for track days, time attack, road racing, and endurance events. Developed by racers for racers, it provides real-time insights to help drivers optimize their performance and improve lap times.

The predictive lap timer delivers instant feedback, allowing drivers to experiment with different lines, braking points, and throttle application. Results are displayed in real-time, with optional voice notifications. For best results, mount your device low and forward in your field of view to track improvements without distraction.

CircuitStorm supports a range of industry-standard data sources:

• RaceCapture data loggers

• Qstarz GNSS receivers
