It now supports distance measurement, useful for training such as running. The G-SQUAD also supports step counting, calorie counting, and interval timer measurement. Newly, it features automatic distance measurement correction through an accelerometer and smartphone connectivity. The new model now connects to smartphones via Bluetooth. By linking with the smartphone's GPS function, it corrects distance measurement using the accelerometer. Once corrected, the watch alone can measure running distance more accurately from the next time onwards. By linking this distance measurement with running time measurement, it supports measurement of running pace and also features an auto-lap function that automatically measures time every time a certain distance is run. Along with the conventional step tracker (step counting function), interval timer (up to 5 sets x 20 sets), lap time measurement (up to 140 laps x 100 runs), and calorie consumption measurement, it supports your daily training.
