JumpFit will track your jump rope workouts telling you how much you’ve jumped, how many calories you’ve burned, and the duration of your workout. You don’t even need the rope!
Using JumpFit is simple. Just hold your iPhone or iPod Touch still in relation to your body, hit the start button, and start jumping. To make the calorie calculations accurate, set your weight in the settings screen. If you like you can setup goals as well to challenge yourself to a new level of fitness.
