For greater accuracy, you must specify which wrist you wear Alta HR on, and which hand you consider dominant. Your dominant hand is the one you use for writing and eating. To start, Wrist Placement is set to Left and Handedness is set to Right. Change either setting in the Fitbit app:
From the Today tab in the Fitbit app, tap your profile picture > Alta HR tile > Wrist Placement or Handedness.
The wristband has two separate bands (top and bottom) that you can swap with accessory bands sold separately.
Remove a band
If you're having trouble removing the band or if it feels stuck, gently move the band back and forth to release it.
Attach a new band
Before you attach a new wristband, first identify the top and bottom bands. The top band has a buckle on it and should be attached on the side closest to the charging port. The bottom band has notches in it.

Alta HR tracks your progress toward a daily activity goal of your choice. When you reach your goal, your tracker vibrates and shows a celebration.
Choose a goal
Set a goal to help you get started on your health and fitness journey. To begin, your goal is 10,000 steps per day. Choose to increase or decrease the number of steps, or to change your goal to distance, calories burned, or active minutes.
For more information, see help.fitbit.com.
Alta HR helps you stay active throughout the day by keeping track of when you're stationary and reminding you to move.

Wear Alta HR to bed to automatically track your time asleep, and sleep stages (time spent in REM, light sleep, and deep sleep). To see your sleep stats, sync your tracker when you wake up and check the Fitbit app.
To start, you have a sleep goal of 8 hours of sleep per night. Customize this goal to meet your needs.

Heart-rate zones help you target the training intensity of your choice. Alta HR shows your current zone and progress toward your maximum heart rate next to your heart-rate reading. In the Fitbit app, you can see your time spent in zones during a particular day or exercise. Three zones based on American Heart Association recommendations are available, or you can create a custom zone if you have a specific heart rate you're targeting.
Default heart-rate zones are calculated using your estimated maximum heart rate. Fitbit calculates your maximum heart rate with the common formula of 220 minus your age.
This is alow-to-medium intensity exercise zone. Thiszone may be a good place to
start for those new to exercise. It's called the Fat Burnzone because a higher percentage of caloriesare burned from fat, but the total calorie burnrate is lower.
Set a custom heart-rate zone or a custom max heart rate in the Fitbit app 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 most people.
For more information, see help.fitbit.com.
After you complete a workout, sync your tracker with the Fitbit app to share your stats with friends and family.

Alta HR continuously tracks your heart rate while you're exercising and throughout the day. If the heart-rate sensor on your tracker has difficulty detecting a signal, dashed lines appear.
If your device doesn't detect a heart-rate signal, first check the Heart Rate setting in the Fitbit app and make sure it's set to On or Auto. Next, make sure you're wearing your tracker correctly, either by moving it higher or lower on your wrist or by tightening or loosening the band. Alta HR should be in contact with your skin. After holding your arm still and straight for a short time, you should see your heart rate again.
