UP is not just an activity tracker-it's a revolutionary, integrated system that incorporates advanced hardware, sophisticated algorithms and data science to better understand your behaviors and habits. Through an in-depth analysis of your eating, activity and sleep patterns, UP is able to intelligently help you make better choices and achieve your goals smarter and faster. How does UP track my movement and activities? The UP2 tracker uses an accelerometer and powerful algorithms to passively track and quantify your activities, distance, calories, active time, and idle time. The UP App also allows you to log a variety of different workout types, so you get credit and estimated caloric burn for non-step-based activities. How does UP track my sleep? The UP2 tracker uses an accelerometer to detect sleep quality and duration. Your band automatically detects when you fall asleep and wake so you do not need to switch modes.
