Tanita Calorism Smart Pedometer
Calorism Smart is just that, a smart way to check your calories: this micro gadget will monitor how much fat you have burned off in grams, as well as calories, walking time and distance, and even how many steps you took.
Coming in five vibrant color designs, you can clip the Calorie Smart to your clothes, put it in your pocket or even attach it as a magnet. A mere 23g (including batteries!) in weight means this is very portable, and the simple three-button functionality also means it is easy to operate too.
