Ive tried at least 14 timer apps. Some were confusing, some impossible. This timer is easy to customize . Create your own workouts, name your own intervals put in your own picture and music or use their presets. A while ago there was an update that created problems with their other app Ultra Timer . I contacted the developers and i shopped for another app but they resolved the issue AND upgraded my app for free to Ultra Trainer. Both timers are Great! Now thats Customer Service.
