This device allows you to monitor your calories at all points of the day, whether you're walking, running, relaxing or working. To lose weight, you have to burn more calories than you consume. It is easier said than done. You can carry CaloriScan around in your pocket. CaloriScan allows you to keep track of how many calories you've burned constantly and provides a motivational boost to help you adjust your daily calorie intake. A unique feature of the CaloriScan is its constant measure of burnt calories. While most monitors only measure your calories when you're active, the CaloriScan measures your calories even during resting periods, such as sitting at a desk. This CaloriScan has a 3D sensor that detects every movement to accurately calculate the number of calories you've burned. It travels easily in your pocked or bag for use anytime and anywhere.
