Custom heart-rate zones
Instead of using the default heart-rate zones, you can configure a custom zone or a
custom max heart rate if you have a specific target in mind. For example, elite
athletes might have a target that differs from the American Heart Association’s
recommendations for the average person. When you’re in your custom zone you’ll
see a solid heart on your tracker. When you’re not in the zone you’ll see an outline of
a heart.
For more details about heart rate tracking, including links to relevant American Heart
Rate Association information, see help.fitbit.com.
Tracking sleep
Wear your Charge 2 to bed to automatically track both your time spent asleep and
your sleep quality. To see your sleep information, sync your tracker when you wake
up and check your dashboard.
Your Fitbit dashboard can recommend consistent bedtimes and wake times to help
you improve your sleep cycle. You can even choose to be reminded nightly when it’s
time to start winding down for bed.

Tracking a daily activity goal
Your Charge 2 tracks your progress towards a daily activity goal of your choice.
When you reach your goal, the tracker vibrates and shows a celebration.
Choosing a goal
By default your goal is 10,000 steps per day. You can change the goal to distance
traveled, calories burned, active minutes, or floors climbed and select the
corresponding value you prefer. For example, you may want to keep steps as your
goal but change the target from 10,000 to 20,000 steps.
Seeing goal progress
A goal progress bar helps keep you motivated. The filled in portion of the bar shown
below indicates that you’re more than halfway to your goal.
