Activity tracker is a device or application for monitoring and tracking fitness-related metrics such as distance walked or run, calorie consumption, and in some cases heartbeat and quality of sleep.
The term is now primarily used for dedicated electronic monitoring devices that are synced wirelessly, to a smartphone (or computer) for long-term data tracking.
Note that we provide complete solution, including wearables (see Fitness bands) and smart phone app (see MyFitness). If used regularly, it can make positive impact on users, and can help them in adopting a healthy life style.
