I am most impressed with this motion measuring app and device. It is the best one I have found so far. The aluminum design is attractive and very durable. You can take it swimming, have it measure cycling, sleep, walking, running and more. It allows you to set daily goals and then tracks your performance in terms of the goals you have entered. It tracks your progress daily, weekly, and over time. In addition to meauring points towards your objectives. It measures steps, calories, and miles. It's an impressive product and the best I have found to date.
