Description by Yating Lu(from the App Store)
Keep your focus on the workout
Core takes care of the intervals, so you can stay with your training. Set your work time, rest time and sets, then follow a clear countdown and audio cues from the first round to the last.
Made for your routine Build a timer for HIIT, Tabata, circuit training or boxing rounds. Save your usual workouts and have them ready when it is time to train again.
Know when to move and when to recover A large countdown and distinct work and rest colors make each phase easy to recognize at a glance. Choose audio cues that suit the way you train.
See the work you have put in Revisit completed sessions and see your weekly training trends. Your training history gives every session a place beyond the final countdown.
