Description
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 • OBD-II scan tools such as OBDLink MX+ and ELM327-based devices • Porsche GT car Wi-Fi modules • Wireless action cameras, including GoPro
Connecting and configuring these devices is straightforward, with built-in verification tools to ensure proper setup before heading out on track. Additional hardware information is available at https://www.petreldata.com.
CircuitStorm also features a comprehensive Vehicle CAN Library, providing real-time access to CAN bus data for supported vehicles. This allows drivers to analyze key vehicle parameters such as:
With one-click configuration, the Vehicle CAN Library simplifies the integration of high-speed vehicle telemetry, delivering a deeper understanding of driving performance.
CircuitStorm includes a preloaded database of race tracks via the Podium platform from Autosport Labs. Drivers can also stream lap data live to Podium for remote monitoring by their team, provided a mobile data connection is available.
Video capture and data overlay are fully integrated, eliminating the need for PC-based editing. Video can be recorded using the mobile device’s built-in camera or wirelessly connected GoPro cameras. The built-in video transcoding engine enables high-quality exports with overlay graphics for detailed post-session analysis.
CircuitStorm’s analysis tools help drivers refine their performance with:
• Lap comparisons to identify inconsistencies • Sectional analysis of braking, acceleration, and cornering performance • Custom data channels to match individual driving styles • Cloud storage and sharing via Petrel Cloud for collaborative analysis
The app includes extensive in-app contextual help, a detailed online user guide, and a support ticketing system to assist users with setup and troubleshooting. Whether new to data logging or an experienced driver, CircuitStorm provides the tools and resources needed to make informed decisions based on real-world telemetry.
Important Notes: • Some features require additional hardware. • A securely mounted mobile device is necessary for accurate lap timing and data logging. • Cloud functionality may require a mobile data connection, subject to carrier charges.

Comments on CircuitStorm - Track Lap Timer for Android
★★★★★Meris Williams· Mar 10, 2023
The lap timer helped me find key areas on track to focus on, and the analysis mode blows away the other apps that I have tried. This app really focuses on driver improvement, which is exactly what I need! Definitely worth the full subscription.
★★★★★Ken Lau· Mar 11, 2023
Been waiting for an elaborate app as such which is truly made by fellow motorsport enthusiasts! Looking forward to use this instead of my current lap timer that doesn't allow true data-logger capabilities.
★★★★★Yarko Petriw· Mar 13, 2023
Excellent data logging software. Have used road racing and the sister app Solo storm for Autocross. Easy to use and very helpful for finding time and improving my driving using data rather than intuition!
★★★★★L·ouĩş Law· Mar 13, 2023
Fantastic app! Great driver-to-driver comparison with videos integration. Valuable data analysis. Easy to use user interface.
