The Genius Fit tracker is great for tracking a variety of activities and has several different functionalities that all provide some useful insight into your daily routines. For example, there's a photoelectric sensor that monitors your heart rate, so if you're working out, you can stay within your target range. It's also got a running mode that helps keep track of your steps and calories. You'll also be able to monitor your sleep quality, which is useful if you find yourself waking up tired more days than not. The watch also allows you to set reminders as well as view notifications and alerts, so you can keep tabs of everything that's going on while you're busy.
