The Go allows you to monitor the number of steps you take each day, how far you travel, and how many calories you have burned. It automatically recognises when you are engaged in activities, so you don't need to press anything to get started. Water-resistant up to 50 m, the fitness band can also monitor your swimming sessions as well as tracking your runs. When the time comes to rest, it can also track your sleeping patterns. All of this information is available using the Health Mate app, available on both Android and iOS. With a clear E-Ink display, you can quickly and easily monitor your daily progress. Clearly visible in bright sunlight and water, you can also access the watch function at any time.Running on a single replaceable button battery, the Go offers up to eight months of battery life. You can choose to wear the device on your wrist, belt, shoe, or even in your pocket. This makes it convenient to track your progress, no matter what you're up to.
