Clockwatts turns your smartphone into a virtual dynamometer that measures your vehicleâs power while driving. The app is designed for track use.
Power is no longer just a number in the specs
The app measures your vehicleâs real-time and peak power and automatically stores all data for later analysis. This allows you to focus on driving and review the results afterward.
âĸ Works fully independently without external devices or vehicle connections.
âĸ Utilizes your phoneâs GPS and built-in sensors to calculate power and speed.
âĸ Compatible with almost any type of vehicle, whether itâs an electric scooter, motorcycle, passenger car, or heavy-duty vehicle.
âĸ Measurement settings can be customized for different vehicles and driving conditions.
âĸ For best results, determine your vehicleâs total weight as accurately as possible before measurement. The settings include example values for other parameters.
âĸ Use the app on a flat surface and preferably in calm weather to ensure the most accurate results.
Power Measurement Report
When the measurement ends, the app automatically generates a clear report of the test results.
âĸ The report includes a line chart showing the vehicleâs power and speed over the measurement period.
âĸ The chart can be saved for later analysis.
âĸ With the phoneâs internal GPS, the maximum measurement duration is typically 30â60 minutes.
âĸ With an external GPS device, the maximum duration is about 10 minutes.
Support for External GPS Devices
âĸ The app supports the RaceBox Mini device, which provides significantly faster location updates and more accurate measurement results.
âĸ It also includes a feature that takes uphill and downhill gradients into account during power measurement -Â this feature is available only when using the RaceBox Mini device.
If you know your carâs exact frontal area, rolling resistance coefficient, and drag coefficient, enter them in the settings â this will provide even more accurate measurement results.
