In the past few years, plenty of companies have released smart wearable fitness trackers. LVL is not your average fitness tracker though. It not only tracks your activity, sleep, mood, and heart rate, it also helps you stay hydrated. You get real-time hydration notifications, wrist-based heart rate tracking, and smart alarm functionality.
LVL lets you know how much you need to drink based on your activity and sweat rate. The device has a full color OLED touchscreen and connects to your smartphone via Bluetooth.[where to get it]
