Setting up your One
You can set up your Fitbit One using your computer or the Fitbit apps for iOS,
Android, or Windows.
Setting up your tracker with the Fitbit app
Over 120 mobile devices and Windows 10 PCs and tablets that support Bluetooth 4.0
technology allow you to set up and wirelessly synchronize your Fitbit One. To see if
your mobile device is compatible with your Fitbit One, visit www.fitbit.com/devices.
If your device is listed, you can then download our app and follow the installation
process in the app. If your device is not listed, check back frequently because we’re
continually adding new devices.
Even if your mobile device is not compatible for syncing via Bluetooth 4.0, you can
still use a Fitbit app to view your data and track your progress—you’ll just need to set
up and sync your tracker using a Mac or PC.
Setting up your tracker using a Mac or PC and Fitbit
Connect
To set up your One using your computer, you’ll first install Fitbit Connect. Fitbit
Connect is the software application that connects (“pairs”) your One to your
fitbit.com dashboard, where you can view your data, log food, and much more.
Mac and PC requirements
Software
Mac OS 10.6 or later
Internet connection
Hardware
USB port
Software
Windows Vista or later
Internet connection
Hardware
USB port
Downloading Fitbit Connect
1. Go to http://www.fitbit.com/setup.
2. Scroll down and click the pink Download button. If the button does not
correctly show your type of computer (for example, if it says “Download for

3
Mac” when you’re on a PC), choose the correct type before clicking the
button.
3. Save the file when prompted.
Installing Fitbit Connect and pairing your tracker
1. Plug your wireless sync dongle into your computer’s USB port and have your
charged tracker nearby.
2. Go to the folder containing the file you just downloaded and look for the
installation program:
- For Mac: Install Fitbit Connect.pkg
- For Windows: FitbitConnect_Win.exe
3. Double-click the file name to install Fitbit Connect.
4. Follow the brief onscreen instructions to finish setting up. You’re ready to get
moving.
Syncing your tracker
Now that Fitbit Connect is installed, your One will automatically and wirelessly sync
with your computer every 20 minutes or so if the following requirements are met:
• Your One is within 15-20 feet of your computer and has new data to upload
(meaning if you haven’t moved, an automatic sync won’t occur).
• Your computer is powered on, awake, and connected to the Internet.
• The wireless sync dongle is inserted into a USB port and is recognized by the
computer.
When One syncs, whether to Fitbit Connect or the Fitbit app, your data is uploaded
to your fitbit.com dashboard. Your One holds detailed minute-by-minute information
for the most recent 7 days and daily activity summaries for 30 days. For the most
accurate dashboard possible, sync your One regularly.
To manually sync your One rather than wait for an automatic sync, click the Fitbit
Connect icon located near the date and time on your computer and click Sync Now.

Wearing your One
The Fitbit 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 Fitbit One is also included in your package. The wristband
should be worn while you sleep. It should not be worn for tracking during the day.
To prevent losing your tracker, wear it:
1. In your pocket.
2. Clipped on your pocket.
3. Clipped on 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 Fitbit One is sweat-proof and rainproof. It is not waterproof and should not be
taken swimming.
