Interval Running App is the only one App allowing to manage your interval running session by vibration way. Without to have a look on the screen, the app launches a specific vibration indicating the speed period and another for the slow period (management by time or distance); the two period are cycled until stop/pause key pressed (number of cycle can be adjusted, set to 0 for infinite cycling). A warm-up and warm-down step can be also adjusted. In real time, it’s reported on the screen: the distance (km and mile), the average or current pace (min:sec by km or mile) and the time elapsed (h:min:sec). When the Heart Rate monitor is connected, the heart rate value is reported on the screen in real time. A HR threshold can be adjusted; a periodical vibration warning (and a signal on screen) is activated as long as the heart rate is higher than the threshold. The session (map, pace, segment…) can be stored with FIT format compatible for Garmin Connect IQ (need to create a Garmin Connect account). For watches without Menu button, the settings menu is accessed by swiping the screen up or down for watches touch screen, or by pressing the up or down button.
