Good but not great.

Love that its completely customizable, has voice prompts, and can be used with the watch. Dislike that there is not a way to copy duplicate activities for more complex interval workouts allowing less time to create. Also have had issues with music stopping if I use sets which completely ruins focus for me. Overall great concept sure with updates will get better.
