Welcome to the Fitbit One™ Wireless Activity + Sleep Tracker.
What you’ll find in the box
Your Fitbit One box includes:
- Fitbit One Wireless Activity + Sleep Tracker
- Clip
- Wireless sync dongle
- Sleep wristband
- Charging cable
What’s in this document
We get you started quickly by creating a Fitbit® account and making sure the tracker can synchronize the data it collects with your Fitbit dashboard. The dashboard is where you can analyze your data, see historical trends, set goals, log food and water, keep up with friends, and much more. As soon as you’re done setting up your tracker, you’re ready to start moving.
Next, we explain how to find and use the features that interest you and adjust your
preferences. To find more information, tips, and troubleshooting, please browse our comprehensive articles at http://help.fitbit.com
Setting up your Fitbit One
To make the most of your One, use the free Fitbit app available for iOS®, Android™, and Windows® 10 mobile devices. If you don’t have a compatible mobile device, you can use a computer and Fitbit.com instead.
Setting up your tracker on your mobile device
The Fitbit app is compatible with more than 200 mobile devices that support iOS,
Android, and Windows 10 operating systems.
To get started:
- Make sure the Fitbit app is compatible with your mobile device by checking
http://www.fitbit.com/devices. - Find the Fitbit app in one of these locations, depending on your device:
- The Apple® App Store® for iOS devices such as an iPhone® or iPad®.
- The Google Play™ Store for Android devices such as the Samsung® Galaxy® S5 and Motorola Droid Turbo.
- The Microsoft® Windows Store for Windows 10 mobile such as the Lumia™ phone or Surface™ tablet.
- Install the app. Note that you’ll need an account with the applicable store before you can download even a free app such as Fitbit.
- When the app is installed, open it and tap Join Fitbit to get started. You’ll be guided through the process of creating a Fitbit account and connecting (pairing) your One to your mobile device. Pairing makes sure the tracker and mobile device can communicate with one another (sync their data).
Note that the personal information you’re asked during setup is used to calculate your basal metabolic rate (BMR), which helps determine your estimated calorie expenditure. This information is private unless you go into your Privacy settings and opt to share age, height, or weight with Fitbit friends.
After setup you’re ready to get moving.
Setting up your tracker on your PC (Windows 10 only)
If you don’t have a mobile device, you can set up and sync your tracker on your Windows 10 PC using the same Fitbit app available for Windows mobile devices.
To get the app, click the Start button and open the Windows Store (called Store).
Search for “Fitbit app.” Note that if you’ve never downloaded an app from the store to your computer, you’ll be prompted to create an account.
Open the app and follow the instructions to create a Fitbit account and set up your One. You can set up and sync wirelessly if your computer has Bluetooth®, otherwise, you’ll need to use the wireless sync dongle that came in the box with your Fitbit One.
Setting up your tracker on your PC (Windows 8.1 and below)
If you don’t have a compatible mobile device, you can set up your tracker with a
computer and see your Fitbit stats on fitbit.com. To use this setup method you’ll first install a free software application called Fitbit Connect that lets One sync its data with your fitbit.com dashboard.
To install Fitbit Connect and set up your tracker:
- Go to http://www.fitbit.com/setup.
- Scroll down and click the option to download.
- When prompted, save the file that appears.
- Double-click the file (FitbitConnect_Win.exe). The Fitbit Connect installer opens.
- Click Continue to move through the installer.
- When prompted, choose Set up a New Fitbit Device.
- Follow the onscreen instructions to create a Fitbit account and connect your One. If your computer has Bluetooth, setup can take place wirelessly. If not you’ll be prompted to plug in the wireless sync dongle that came in the box with your Fitbit One.
Note that the personal information you’re asked for during setup is used to calculate your basal metabolic rate (BMR), which helps determine your estimated calorie expenditure. This information is private unless you go into your Privacy settings and opt to share age, height, or weight with Fitbit friends.
Setting up your tracker on your Mac
If you don’t have a compatible mobile device, you can set up your tracker with a computer and see your Fitbit stats on fitbit.com. To use this setup method you’ll first install a free software application called Fitbit Connect that lets One sync its data with your fitbit.com dashboard.
To install Fitbit Connect and set up your tracker:
- Go to http://www.fitbit.com/setup
- Scroll down and click the option to download.
- When prompted, save the file that appears.
- Double-click the file (Install Fitbit Connect.pkg). The Fitbit Connect installer opens.
- Click Continue to move through the installer.
- When prompted, choose Set up a New Fitbit Device.
- Follow the onscreen instructions to create a Fitbit account and connect your
One.
Note that the personal information you’re asked during setup is used to calculate your basal metabolic rate (BMR), which helps determine your estimated calorie expenditure. This information is private unless you go into your Privacy settings and opt to share age, height, or weight with Fitbit friends.
Syncing your tracker data to your Fitbit account
Once you’ve set up and started using One, you’ll need to make sure it regularly transfers (syncs) its data to Fitbit so you can track your progress, see your exercise history, earn badges, analyze your sleep logs, and more on your Fitbit dashboard. A daily sync is recommended but not required.
The Fitbit apps use Bluetooth Low Energy (BLE) technology to sync with your Fitbit tracker. Each time you open the app it will sync if the tracker is nearby, and the app will also sync periodically throughout the day if you have the all-day sync setting enabled. If you’re running the Fitbit app on a Windows 10 PC that doesn’t have Bluetooth, you’ll need to make sure the tracker is connected to the computer.
Fitbit Connect on a Mac® also uses Bluetooth for syncing (if available), otherwise, you’ll need to make sure your wireless sync dongle is plugged into the computer. Fitbit Connect on a PC requires that you plug in your wireless sync dongle.
You can force Fitbit Connect to sync at any time or it will happen automatically every 15 minutes if:
- Your tracker is within 20 feet of your computer and has new data to upload
(meaning that if you haven’t moved, an automatic sync won’t occur). - The computer is powered on, awake, and connected to the Internet.
Getting to know your Fitbit One
This section tells you how best to wear and recharge your tracker.
Placement
The One is most accurate when worn on or very close to your torso. A clip designed to keep the tracker secured to your clothing is included in your package.
A sleep wristband for your One is also included in your package.
To avoid losing your tracker, we recommend that you wear it in your pocket, clipped to your pocket, or clipped to your bra.
The One is not designed to be worn in direct contact with the skin. Always use the silicone holder when clipping it to a bra or waistband, with the display facing outward. Do not wear the One inside your bra.
Some users may experience skin irritation even when wearing the One as instructed on the bra or waistband. If this occurs we recommend clipping it on your pocket, belt, or other external piece of clothing.
The One is sweat-proof and rainproof. It is not waterproof and should not be taken swimming.
Changing the display for left-handed use
By default your tracker is oriented for right-handed individuals. If you’re left-handed, you can reorient the display to make it easier to read. To do so, log into your fitbit.com dashboard and click the gear icon in the upper right. Click Settings > Devices and then find and adjust the Left-handed button.
Battery life and charging
The One is powered by a rechargeable built-in battery. Your fully charged One has a battery life of up to two weeks.
Determining your current battery level
You can check your battery level in a couple of places:
- While charging your One, press the button on your tracker to view the battery
indicator on screen. - On your fitbit.com dashboard.
Charging your tracker
To charge your One, align the gold contacts on your tracker with the gold contacts on the inside of the charging cable, then plug the cable into your computer’s USB port. Charging typically takes about an hour.
Note: Every night at midnight, your tracker will reset itself. This means your goal progress and daily data will begin at zero again. This does not delete the data stored on your tracker. That data will be uploaded to your dashboard the next time you sync your tracker. The time this reset occurs is based on the time zone set on your fitbit.com profile.
Tracking with Fitbit One
Your One tracks a variety of stats automatically whenever you’re wearing it. Your
tracker’s latest data is uploaded to your Fitbit dashboard whenever you sync.
Viewing all-day stats
Press the button on your One to see the time of day and cycle through these all-day stats:
- Steps taken
- Floors climbed
- Recent activity levels (represented by an expanding flower)
- Distance traveled
- Calories burned
Note that your One resets at midnight according to the time zone you’ve selected for your account. The reset ensures that One can track your daily totals correctly, and does not delete the previous day’s data. All your data will appear on your dashboard when you sync your tracker.
Using the display
When you first set up your One and press the button to scroll through your stats, you see the stat category (e.g. STEPS) followed by the stat and its icon. After you’ve cycled through each screen 5 times and can recognize the stat icon, the stat
category no longer appears so that you can scroll more quickly.
Any time your tracker is reset, it will enter “beginner mode” and show the stat category again for the first 5 cycles. This will happen if you shut down and then
restart your tracker, upgrade your tracker, or charge your tracker after the battery drained completely.
Tracking sleep
You can use your One to track how long and how well you sleep. The One will track your movement throughout the night to provide you with information about the quality of your sleep.
- Place your tracker into the slot in your wristband and wrap it around your
non-dominant wrist. - Once you are in bed and ready to fall asleep, press and hold the tracker’s
button for 2+ seconds. You will see a blinking stopwatch and clock. The other
icons will also blink, indicating that your tracker is in sleep mode. - When you wake up, press and hold the button for 2+ seconds to stop the
sleep recording. The icons will stop blinking to indicate you’ve exited sleep
mode. Once you exit sleep mode, your tracker will resume, displaying your
daily totals.
Once the data syncs, graphs on your dashboard will reveal how long you slept and
the number of times you woke up. You can also use your dashboard to set a goal for hours slept.
Note: If you forgot to press the button on your tracker, but were wearing it while you slept, you can enter your sleep times manually in your online sleep log.
Tracking exercise
Though your One automatically tracks several stats throughout the day, you can also track stats for a specific exercise or workout as well. Similar to the trip mode on a car’s odometer, activity mode brings closer scrutiny to a specific time period.
For example, if you put your One in activity mode and go for a run, you can view
stats measured for that run, such as calories burned or steps taken. When you end
activity mode at the end of the run and sync your data, your can log in to your
fitbit.com dashboard and see a summary of the activity’s stats such as pace,
duration, and more.
To start a recording, hold your tracker’s button down for 2-3 seconds until a flashing stopwatch and running numbers appear as they do in sleep mode.
During the activity the display icons will blink. When you press the tracker’s button to cycle between screens, the stats represent the activity that has occurred since the
recording started.
To exit activity mode, hold your tracker’s button down for 2-3 seconds until the icons and numbers on the display stop flashing.
Using the fitbit.com dashboard
Fitbit provides a free online tool — the fitbit.com dashboard — to help you track, manage, and evaluate your fitness progress. Use the dashboard to see your daily totals, analyze details about specific activities, view historical graphs, and log food.
