With Garmin's Vivofit fitness band, you have an easy-to-read device that learns your activity level and assigns a personalised daily goal to keep you motivated.
Displaying steps, calories and distance upon its crystal clear 25.5 x 10mm screen, it even monitors your sleep to ensure you are getting the most out of every hour of the day.
As you meet your milestones, Vívofit will adjust your goal for the next day, gradually nudging you toward a healthier lifestyle. Using Garmin Connect™, the brand's free-to-use fitness community, you can earn virtual badges and view your progress. Using this service, you can also join online challenges with other Vívofit users or start your own competition with friends to compete for virtual badges and bragging rights.
You can access the free online community from your computer or on your compatible mobile device with the Garmin Connect™ Mobile app..
