Step Cal for iPhone

From Must Have It:

Step Cal determines your running speed, amount of steps you have done reaching your working place, and burned calories after a walk. You can set your step length manually or have Step Cal guess it from your height. You can switch between English and metric measurement units by tapping on the km/h or mph label. You can also set your weight and Step Cal will estimate the number of calories that you burn while walking or jogging. Step Cal will give you acoustic signals after a number of steps, a distance, a number of calories burned, or a time interval of your choice.
