TrainHR Pro

TrainHR Pro is a performance-focused heart rate training application designed for athletes and active individuals who want to train with precision instead of guesswork. By using the Karvonen method, TrainHR Pro helps you calculate personalized heart rate zones that are tailored to your body and fitness level.
Many training apps rely only on maximum heart rate, which can lead to inaccurate intensity targets. The Karvonen method goes a step further by incorporating resting heart rate, resulting in more individualized and realistic training zones. This makes TrainHR Pro especially useful for athletes who care about efficiency, recovery, and long-term performance improvement.
