Introducing PowerTap PowerCal, the worlds' first-ever power meter calculated from heart rate. For years there has been a widely recognized correlation between power and heart rate. In a lab, one can predict power output or intensity by knowing heart rate and vice versa. But once you leave the lab and encounter variables such as hills, wind and fatigue, the relationship gets a bit trickier to predict. This is why many cyclists and triathletes use both a heart rate monitor and a power meter in training.

Through the analysis of tens of thousands of power files over the years, the experts at PowerTap and the University of Colorado Boulder have identified patterns, which can correlate an athlete's heart rate to power across all real world conditions. We've utilized this knowledge to create a technology that provides power based on this correlation, in the real world and in real time.

No, it's not as precise as our PowerTap. Yes, it's a great tool, is incredibly easy to use, and is Bluetooth Smart compatible and will provide all the workout data you need via the PowerTap mobile app. Simply pair it to your display, and off you go!

We're all familiar with the key difference between a power meter and a heart rate monitor: that heart rate is a response to the work you're doing, whereas power is the actual work. The algorithms in PowerCal translate heart rate data into the vernacular of power-based training - watts, kilojoules, peak power, etc.

It could be one of the best investments you make in your training. So if you're ready to take your performance to the next level, let PowerCal help get you there.
