Distance measurements via the accelerometer are corrected by linking with smartphone GPS functions via Bluetooth connection. In addition to tracking running pace by comparing the distance measured with running time, it is also equipped with an auto lap function. It supports daily training via the combination of a conventional step tracker, an interval timer, a lap timer, and a calorie consumption calculator. It also has dedicated Life Log and Activity History apps, and allows for automatic creation of training plans. Uses a high-definition MIP LED for the display, and is also equipped with a super illuminator. A soft urethane material is used for the band for a more comfortable fit, and a large number of band holes are provided for fine adjustment. It also has a battery life of about two years even when using multiple functions every day. Useful for a wide range of purposes, from daily health management to improving running endurance.
