The Alta HR Fitness Tracker is Fitbit’s slimmest design and aims to help users reach health goals in style. The tracker features PurePulse® Heart Rate that tracks the heart rate continuously on the wrist and using the heart rate zones, users will be able to see how intense their workouts are and be able to increase or decrease their efforts accordingly. SmartTrack™ allows for auto detection for workouts such as running and the likes and automatically logs them to the dashboard. Along with this is calorie burn tracking of accurate measurement as well as steps and distance tracking that can be tracked all day where a simple tap on the OLED display will show progress. Alta HR’s battery can last up to 7 days on a single charge even when worn overnight to track sleep and the silent alarm is used. Sleep stages can be shown, whether light, deep or REM, through the heart rate and sleep quality can be understood better. Finally, Alta HR is also designed to display a customizable clock and receive call, text and calendar alerts from the connected smart phone and also has convenient on-screen reminders that help reach step goals.
