Color - BlueThe Nuband Story:Since life and the world in general have become more demanding, health and exercise have become important factors in all our daily lives. All our time is taken up by work, family, friends, and social media. This leaves very little time to focus on our health and well-being.We at Nuband liked what other wearable products were doing. However, we saw a major obstacle for the everyday, common person - the affordability of these products. Essentially, Nuband allows the fitness conscience owner to track their exercise and sleep, and to set goals that they can meet to improve their health and well-being. And, this shouldn’t cost the earth! Therefore, we wanted to create something lightweight, attractive, and functional but, most of all, affordable!The philosophy of the “NU” family of products has always focused on design and functionality at an affordable price. Therefore, we source the same materials as the premium brands, and ensure premium quality standards of all our products. However, we pass the savings to the end user.Now, with Nuband, everyone can afford to improve their health and well-being by tracking their workouts and setting their goals!Nuband’s mobile app works with most Apple devices and Android devices including Samsung Galaxy S3, S4 and S5.From the ManufacturerDo you want to be fit and sleep well?
