Clockwatts: Power measurement

Clockwatts turns your smartphone into a virtual dynamometer that measures your vehicle's power while driving. The app is designed for performance analysis in track environments. Power Is More Than Just a Specification Measure your vehicle's real-time and peak power output while driving. Clockwatts automatically records every measurement, allowing you to focus on driving and review the results later. Features • Works completely independently without connecting to your vehicle. • Uses your device's location services to measure vehicle performance. • Compatible with almost any vehicle, including electric scooters, motorcycles, passenger cars, vans, and heavy vehicles. • Measurement settings can be customized for different vehicles and testing conditions. • Measurements continue even when your phone's screen is locked. • Includes storage for up to 10 measurement reports. Choose the Version That Fits Your Needs FREE • Free version of the app. • Includes essential power measurement features. • Measurement results are displayed as rounded values. DYNO • Full measurement precision for power testing. • Automatic measurement mode. • Support for the RaceBox Mini Bluetooth GPS device. PERFORMANCE • Includes all DYNO features. • Adds speed, acceleration, and tractive force measurements. • Includes cropping and analysis tools for measurement reports. Select any section of a measurement and view its minimum and maximum speed, elapsed time, and distance traveled. Ideal for analyzing runs such as 0–60 km/h, 0–100 km/h, 100–200 km/h, and quarter-mile acceleration. Measurement Reports After each measurement session, Clockwatts automatically generates a detailed report. • Reports display the collected measurement data as easy-to-read line graphs. • When using your phone's built-in GPS, the maximum recording duration is typically 30–60 minutes. • When using an external GPS receiver, the maximum recording duration is approximately 10 minutes. External GPS Support • Clockwatts supports the RaceBox Mini, providing significantly faster location updates and improved measurement accuracy. • An additional gradient compensation feature accounts for uphill and downhill driving during power measurements. This feature is available only when using the RaceBox Mini. For even greater accuracy, you can manually enter your vehicle's frontal area, rolling resistance coefficient, and drag coefficient in the settings if these values are known.
