Both the Fitbit Charge HR and Surge fitness bands now come with the Smart Track feature, which automatically senses when a user begins exercising. It will even sense what type of exercise you had started – in other words, if you’re running, biking, walking, playing certain sports, or even taking Zumba classes, your Fitbit band will know exactly what you’re doing. All information is sent back to your Fitbit app, may it be the smartphone app or PC/laptop program, without requiring you to go through menus.
A second new feature for the Android and iOS versions of the Fitbit app is Exercise Goals. This allows users to set weekly targets and get daily updates on their progress. So if you’re on a specific training schedule or have a certain amount of weight you want to lose by a certain point in the year, your Fitbit will remind you about that and help you effectively set your goals.
The update also comes with a revamped version of PurePulse, which allows for better heart rate monitoring during intensive workouts. This should help users in determining whether they’re doing the right exercise at the right level of intensity.
