Take your workouts to the next level.  IntervalCoach is an easy to use High/Low intensity interval workout tracker.  Progress can be checked with quick glance.  Clock and interval progress are shown in large fonts.  High intensity is indicated by red background; Low with green.  Sounds remind you of the cycle you are entering.  A delay feature allows time to stow the device before beginning your workout. 
 
There are settings for varying the start of the workout and the duration of both the high and low intervals.  Number of intervals can also be adjusted.  All of these are set with easy to use sliders.  Press and hold sliders before moving and it shows the setting above. Additionally, the sounds and device vibration can be turned on/off.  The sounds will emit over any playing music but will not stop any music being listened to.  Ship bell sounds signal the start of high intensity and school bell sounds signal start of low intensity.  
 
All the settings come preconfigured.  Any adjustments made are saved for the next workout!  The application is available in English and Spanish as well as landscape and portrait.
 
Always consult with a physician before starting any new exercise program.  This is especially true when starting or changing a high intensity workout.
