The majority of heart rate regulation apps require manual adjustment of desired heart rates, leading to over- and under-exertion.

University of Utah researchers have created an application and wearable for automatic, personalized, high accuracy heart rate regulation. The user inputs their desired heart rate plan, and a wearable heart rate sensor provides real-time bio-feedback to influence audible cues produced by the application. This adaptive audible signal gives the runner a live, calculated cadence by which to adjust their pace.
