Smart Intensity is a High Intensity Interval Training (HIIT) workout app for the Apple Watch which incorporates haptic (feeling taps on your wrist) and auditory (sounds and/or voice) guidance throughout your routine. As you alternate between high and low intensity phases, Smart Intensity will track your heart rate using your Apple Watch and let you know when you need increase or decrease your difficulty to achieve the recommended heart rate. HIIT routines offer many health benefits in less time than other workout routines. Smart Intensity guides you in achieving those results easily.
