CalmDriver

CalmDriver helps you understand and improve your driving efficiency using only your smartphone.

The app analyzes motion data from GPS and device sensors to evaluate how smoothly and efficiently you drive. Instead of relying on vehicle data or OBD connections, CalmDriver uses a physics-based model to estimate how your driving style impacts energy consumption.

Key features:

• Driving score (0–100)
Get a clear, easy-to-understand score that reflects how efficiently you drive.

• Real-time metrics
Track speed, smoothness, and peak acceleration during your trip.

• Trip analysis
Review past trips and understand what affected your score.

• Driving insights
Identify hard braking, aggressive acceleration, and unstable speed patterns.

• Fully offline
No internet connection required. All calculations are done locally on your device.

How it works:

CalmDriver analyzes your speed and acceleration over time to estimate how much energy your driving style requires. Smooth acceleration, stable speed, and gentle braking lead to better scores. Aggressive inputs increase energy usage and reduce efficiency.

This approach works for any type of vehicle:
• gasoline
• diesel
• electric
• hybrid

Why use CalmDriver:

• Improve fuel or battery efficiency
• Extend driving range
• Reduce wear on brakes and tires
• Develop smoother, more controlled driving habits

CalmDriver is not about driving slower — it’s about driving smarter.

Start a trip, drive as usual, and see how your style affects efficiency.
