What’s in this manual

We’ll explain how to create a Fitbit® account and make sure your tracker can
transfer the data it collects to your dashboard. The dashboard is where you’ll set
goals, analyze historical data, identify trends, log food and water, keep up with
friends, and much more. As soon as you’re done setting up Alta HR, you’re ready to
start moving.

Next, we’ll explain how to find and use the features that interest you and how to
adjust your preferences. For more information, tips, and troubleshooting, browse
our comprehensive help content at help.fitbit.com

Set up Fitbit Alta HR

For the best experience, use the Fitbit app for iOS, Android, or Windows 10. If you
don’t have a smartphone or tablet, you can also use a computer and fitbit.com
instead, but keep in mind that a phone is required for call, text, and calendar

Your Fitbit account asks for information such as height, weight, and sex in order to
calculate your stride length and to estimate distance, basal metabolic rate, and
calorie burn. When you set up your account, your name and photos are visible to all
other Fitbit users. You have the option to share other information, but most of the
information you provide is private by default.

Charge Alta HR

To charge your tracker:

  • Plug the charging cable into the USB port on your computer or a UL-certified
    USB wall charger.
  • Clip the other end of the charging cable to the port on the back of the tracker.
    The pins on the charging cable must lock securely with the port. You’ll know
    the connection is secure when the tracker vibrates and you see a battery icon
    on your tracker’s display. The battery icon disappears after three seconds

Charging fully takes about one to two hours. While the tracker charges, you can tap
it to check the battery level. A fully charged tracker shows a solid battery icon.

Set up with your phone or tablet

The free Fitbit app is compatible with more than 200 devices that support iOS,
Android, and Windows 10 operating systems.

To get started:

  • Find the Fitbit app in one of the locations below, depending on your device. If
    you’re unsure if the Fitbit app is compatible with your phone or tablet, see
    fitbit.com/devices                                                                                     -Apple App Store for iOS devices such as an iPhone or iPad.                          -Google Play Store for Android devices such as the Samsung Galaxy S8 and Google Pixel.                                                                                            -Microsoft Store for Windows 10 devices such as the Lumia phone or Surface tablet.

    one before you can download the app.
  • When the app is installed, open it and tap Join Fitbit to be guided through a
    series of questions that help you create your Fitbit account, or log in to your
    existing account.
  • Continue following the on-screen instructions to connect, or “pair,” Alta HR to your phone or tablet. Pairing makes sure the tracker and phone or tablet can
    communicate with one another (sync data back and forth).

When you’re done pairing, read through the guide to learn more about your new
tracker and then explore the Fitbit dashboard.

    series of questions that help you create your Fitbit account, or log in to your
    existing account.
  • Continue following the on-screen instructions to connect, or “pair,” Alta HR to your computer. Pairing makes sure the tracker and computer can communicate with one another (sync data back and forth).

When you’re done pairing, read through the guide to learn more about your new
tracker and then explore the Fitbit dashboard.

Set up with your Mac

If you don’t have a compatible phone or tablet, you can set up your tracker with a
Bluetooth-enabled Mac and use the fitbit.com dashboard to see your stats. To use
this method you’ll first install a free software application called Fitbit Connect that
lets Alta HR sync its data with your fitbit.com dashboard.

To install Fitbit Connect and set up your tracker:

  • Go to fitbit.com/setup
  • Scroll down and click the option to download for Mac.
  • If prompted, save the file that appears.
  • Find and double-click the file to open the installer program (Install Fitbit
  • Click Continue to move through the installer
  • When prompted, choose Set up a New Fitbit Device.
  • Follow the on-screen instructions to create a Fitbit account, or log in to your
    existing account.

When you’re done with the setup, Fitbit guides you through an introduction to Alta
HR and takes you to the fitbit.com dashboard.

Sync data to your Fitbit account

Regularly sync Alta HR to transfer data to your dashboard. The dashboard is where
you’ll track your progress, see exercise history, track your sleep patterns, log food
and water, identify trends, participate in challenges, and much more. We recommend syncing at least once a day.

The Fitbit app and Fitbit Connect use Bluetooth Low Energy technology to sync
data with Alta HR.

Each time you open the Fitbit app, Alta HR syncs automatically when it’s nearby.
Alta HR also syncs with the app periodically if All-Day Sync is on. To turn on this

From the Fitbit app dashboard, tap or click the Account icon ( ) > Alta HR tile
> All-Day Sync.

You can also use the Sync Now option in the app at any time.

Fitbit Connect on your Mac syncs every 15 minutes if the tracker is within 30 feet of the computer. To force a sync, click the Fitbit Connect icon located near the date
and time on your computer and choose Sync Now.

Wear Alta HR

Place Alta HR around your wrist. If you need to attach a different size wristband, or if you purchased an accessory wristband, you’ll find instructions in “Change the
wristband” on the next page.

Placement for all-day wear vs exercise

When you’re not exercising, wear Alta HR a finger’s width below your wrist bone.

For optimized heart-rate tracking while exercising, keep these tips in mind:

  • Try wearing Alta HR higher on your wrist during exercise for an improved fit
    and more accurate heart-rate reading. Many exercises, such as bike riding or
    weight lifting, cause you to bend your wrist frequently, which can interfere
    with the heart-rate signal if the tracker is lower on your wrist.

  • Make sure the tracker is in contact with your skin.
  • Don’t wear your tracker too tight; a tight band restricts blood flow, potentially
    affecting the heart-rate signal. However, the tracker should be slightly tighter
    (snug but not constricting) during exercise than during all-day wear.
  • With high-intensity interval training or other activities where your wrist is
    moving vigorously and non-rhythmically, the movement may limit the sensor’s ability to provide a heart-rate reading. If your tracker doesn’t show a heart-rate reading, try relaxing your wrist and staying still briefly (about 10 seconds). You should see a heart-rate reading.

Wrist choice and dominant hand

For greater accuracy and ease of use, Alta HR needs to know which wrist you wear
it on (right or left) and which hand you consider dominant (right or left). Your
dominant hand is the one you usually write or throw with.

During setup, you’re asked to choose the wrist where you’re going to wear Alta HR.
Should you later decide to move Alta HR to the other wrist, change the Wrist
setting. You can also change your dominant hand at any time with the Handedness
setting. Both settings are found in the Account section of the Fitbit app.

Change the wristband

The wristband has two separate bands (top and bottom) that you can swap with
accessory bands sold separately.

Remove a wristband

To remove the wristband:

  • Turn Alta HR over and find the band latches—there’s one on each end where the band meets the frame.
  • To release the latch, press down on the flat metal button on the strap.

  • Slide the band up to release it from the tracker.

  • Repeat on the other side.

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 wristband

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.

To attach a band, slide it down on the end of the tracker until you feel it snap into


Learn how best to navigate, check the battery level, and care for your tracker.

Alta HR has an OLED tap display that can be oriented horizontally or vertically. You can choose from several clock faces, each with a unique design. Single-tap the
display to flip through your stats.

When you’re not using Alta HR the display is dimmed. To wake it up:

  • Double-tap your tracker.
  • Turn your wrist towards you. This behavior, known as Quick View, can be
    turned off in your tracker settings.

For best results, tap your tracker where the screen meets the band as shown.

Check battery level

Your fully charged Alta HR has a battery life of up to 7 days. Note that battery life
and charge cycles vary with use, settings, and many other factors. Actual results will

If your battery is low, when you wake up your Alta HR you’ll see low battery icon
after a few seconds. If you see a critical battery icon you’ll be unable to flip through
your stats until you charge your tracker. Your tracker continues to track your activity until your battery runs out. Note that heart rate tracking will stop when your battery level is at approximately 5%.

You can check your battery level at any time on the battery screen on your tracker
or on your Fitbit dashboard. You must turn on the battery screen in the Fitbit app, it is not on your tracker by default.

Care for Alta HR

It’s important to clean and dry your Alta HR regularly. For instructions and more
information, see fitbit.com/productcare

Activity and Sleep

Alta HR continuously tracks a variety of stats whenever you wear it. The information is transferred to your dashboard every time you sync your tracker.

View all-day stats

Tap your Alta HR to see these all-day stats:

  • Steps taken
  • Current heart rate
  • Resting heart rate (optional)
  • Distance covered
  • Calories burned
  • Active minutes

Other stats captured by your tracker are available on your Fitbit dashboard, including:

  • Your sleep history, including hours slept and sleep patterns
  • The hours of the day that you were stationary vs. active (walked at least 250
  • Your exercise history and progress towards a weekly exercise goal
  • Your beats per minute (BPM), average resting heart rate, and time spent in
    heart-rate zones.

Note: Alta HR stats reset at midnight to begin a new day.

Double-tap your Alta HR to wake it up. When you see the clock, tap to see each of
your stats in turn. If you have an alarm set, you’ll also see the next alarm time.

Check your heart rate

Alta HR allows you to view your real-time heart rate and your resting heart rate on
your tracker. To view your heart rate, tap your tracker until you get to the heart rate
screen where you’ll see your current heart rate. Tap again until you get to the
resting heart rate screen to see your resting heart rate. You must turn on the resting
heart rate screen in the Fitbit app.

Using heart-rate zones

Heart-rate zones help you target the training intensity of your choice. Your tracker
shows your current zone beside your heart rate, and on your Fitbit dashboard you
can see your time spent in zones during a particular day or exercise. Three zones
based on American Heart Association recommendations are available by default, or
you can create a custom zone if you have a specific heart rate you’re targeting.

Default heart-rate zones

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.

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

Track a daily activity goal

Alta HR tracks your progress towards a daily activity goal of your choice. When you
reach your goal, the tracker vibrates and shows a celebration.

Choose a goal

By default your goal is 10,000 steps per day. You can change the goal to distance
traveled, calories burned, or active minutes 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.

See goal progress

A goal progress bar helps keep you motivated. The dots in the bar shown below
indicate that you’re more than halfway to your goal.

Track your exercise

The SmartTrack feature automatically detects selected exercises and records the
details in your exercise history.

By default, SmartTrack detects continuous movement at least 15 minutes in length.
You can increase or decrease the minimum duration or disable SmartTrack for one
or more exercise types.

For more information about customizing and using SmartTrack, see help.fitbit.com

Track your hourly activity

Alta HR helps you stay active throughout the day by keeping track of when you’re
stationary and reminding you to move.

If you haven’t walked at least 250 steps in a given hour, at 10 minutes before the
hour you’ll feel a vibration reminding you to walk. When you meet the 250-step
goal after receiving the reminder, you’ll feel a second vibration and see a
congratulatory message.

For more information on hourly activity, including how to customize the hours you
receive reminders, see help.fitbit.com

Track your sleep

Wear Alta HR to bed to automatically track your time asleep and sleep stages. To
see your sleep stats, sync your tracker when you wake up and check your

For more information about sleep tracking, see help.fitbit.com

Set a sleep goal

By default, you have a sleep goal of 8 hours of sleep per night. Customize this goal
to meet your needs.

For more information about your sleep goal, including how to change it, see

Set a bedtime reminder

The Fitbit dashboard can recommend consistent bedtimes and wake times to help
you improve the consistency of your sleep cycle. You can choose to be reminded
nightly when it’s time to start getting ready for bed.

For more information about how to set bedtime reminders, see  help.fitbit.com

Learn about your sleep habits

Alta HR tracks several sleep metrics including when you go to bed, how long you’re
asleep, and your time spent in each sleep stage. When you use Alta HR with the
Fitbit dashboard, your tracker can help you understand how your sleep patterns
compare to others of the same sex and age range.

For more information about sleep stages, see  help.fitbit.com

Set a silent alarm

Alta HR can gently vibrate to wake or alert you with a silent alarm. You can set up to eight alarms to recur every day or on particular days of the week only. When the
alarm goes off, simply double tap to dismiss.

Alta HR continuously tracks your heart rate while you’re exercising and throughout
the day. Occasionally, the heart-rate sensor on your tracker may have difficulty
finding a good signal. When this happens, you’ll see dashed lines where your
current heart rate usually appears.

If you’re not getting a heart-rate signal, first 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.

If the heart rate signal is still missing, check your Heart Rate setting on your Fitbit
dashboard and make sure it’s set to On or Auto.

Unexpected behavior

If you experience one of the following problems, it may be fixed by restarting your

  • Not syncing despite successful setup
