LVL Hydration Monitor
Just about every smart device and fitness tracker can estimate calories burnt or steps taken. The LVL Hydration Monitor instead takes a stab at measuring hydration, which is easier said than done. Using NIRS red light technology validated by numerous studies and used in various medical settings, LVL safely shines light into your skin and analyses your level of hydration, stratifying your current state across several levels — and reminding you to drink not only when you’re thirsty but also when your body needs it, especially during and following strenuous exercise. The wristband also precisely measures heart rate and tracks activity, including steps taken, distance covered, floors climbed, and calories expended, also transmitting all data gathered to your smartphone for further analysis.
