Clockwatts - Car power meter

The Clockwatts turns your smartphone into a virtual dyno meter that measures car power while driving. The application is designed for track conditions.

Power is no longer just numbers in the car's technical specifications
You can see the current and maximum power of the car in real time.
• The application works independently on the phone, without external devices or connections to the vehicle.
• The measurement uses the device's location data and internal sensors.
• The power measurement settings can be adjusted to suit different cars and conditions. Use the application on a flat area.
• You only need to know the total weight of the car. The settings contain examples for other values.

Power Measurement Report
When you stop the power measurement, a report is automatically generated for the measurement period. The report includes a clear line graph showing the vehicle's power and speed during the session. You can save the graph for later review. The maximum length of the measurement period depends on the device's GPS capabilities – typically around 30–60 minutes with a phone and about 10 minutes with an external GPS device.

Support for External GPS Devices
• The app is also compatible with the RaceBox Mini device.
• RaceBox Mini enables significantly faster measurement data updates and improved accuracy.

If you know your car’s exact frontal area, rolling resistance coefficient, and drag coefficient, enter them in the settings – this will provide even more accurate measurement results.
