Get started
Fitbit Sense is the advanced smartwatch that helps you tune in to your body
with tools for heart health, stress management, skin temperature trends, and
more. Take a moment to review our complete safety information at
fitbit.com/safety. Sense is not intended to provide medical or scientific
data.
What’s in the box
Your Sense box includes:
Watch with small band (color and material varies)
Charging cable
Additional large band
The detachable bands on Sense come in a variety of colors and materials, sold separately.
7
Charge your watch
A fully-charged Sense has a battery life of 6+ days. Battery life and charge
cycles vary with use and other factors; actual results will vary. To charge
Sense:
1. Plug the charging cable into the USB port on your computer, a UL-certified
USB wall charger, or another low-energy charging device.
2. Hold the other end of the charging cable near the port on the back of the
watch until it attaches magnetically. Make sure the pins on the charging cable
align with the port on the back of your watch.
Charge Sense for 12 minutes for 24 hours of battery life. While the watch
charges, tap the screen twice or press the button to turn the screen on. The
battery level appears for several seconds, then disappears so you can use your
watch while it charges. Charging fully takes about 1-2 hours.
8
Set up Sense
Set up Sense with the Fitbit app for iPhones and iPads or Android phones. The
Fitbit app is compatible with most popular phones. See fitbit.com/devices to
check if your phone is compatible.
To get started:
1. Download the Fitbit app: l Apple App Store for iPhones l Google Play Store
for Android phones
2. Install the app, and open it.
l If you already have a Fitbit account, log in to your account
tap the
Today tab
your profile picture Set Up a Device.
l If you don’t have a Fitbit account, tap Join Fitbit to be guided through a
series of questions to create a Fitbit account.
3. Continue to follow the on-screen instructions to connect Sense to your
account.
When you’re done with setup, read through the guide to learn more about your new watch and then explore the Fitbit app.
For more information, see the related help article.
9
Connect to Wi-Fi
During setup, you’re prompted to connect Sense to your Wi-Fi network. Sense
uses Wi-Fi to more quickly transfer music from Pandora or Deezer, download
apps from the Fitbit Gallery, and for faster, more reliable OS updates. Sense
can connect to open, WEP, WPA personal, and WPA2 personal Wi-Fi networks. Your
watch won’t connect to 5GHz, WPA enterprise, or public Wi-Fi networks that
require more than a password to connect–for example, logins, subscriptions, or
profiles. If you see fields for a username or domain when connecting to the
Wi-Fi network on a computer, the network isn’t supported. For best results,
connect Sense to your home Wi-Fi network. Make sure you know the network
password before connecting. For more information, see the related help
article.
See your data in the Fitbit app
Open the Fitbit app on your phone to view your activity, health metrics, and
sleep data; log food and water; participate in challenges; and more.
10
Unlock Fitbit Premium
Fitbit Premium is your personalized resource in the Fitbit app that helps you
stay active, sleep well, and manage stress. A Premium subscription includes
programs tailored to your health and fitness goals, personalized insights,
hundreds of workouts from fitness brands, guided meditations, and more. Sense
includes a 6-month Fitbit Premium membership for eligible customers in certain
countries. For more information, see the related help article.
11
Wear Sense
Wear Sense around your wrist. If you need to attach a different size band, or
if you purchased another band, see the instructions in “Change the band” on
page 15.
Placement for all-day wear vs. exercise
When you’re not exercising, wear Sense a finger’s width above your wrist bone.
In general, it’s always important to give your wrist a break on a regular
basis by removing your watch for around an hour after extended wear. We
recommend removing your watch while you shower. Although you can shower while
wearing your watch, not doing so reduces the potential for exposure to soaps,
shampoos, and conditioners, which can cause long-term damage to your watch and
may cause skin irritation.
For optimized heart-rate tracking while exercising: l During workouts, try
moving the band higher on your wrist to get a better fit. If you experience
any discomfort, loosen the band, and if it persists give your wrist a break by
taking it off.
12
l Wear your watch on top of your wrist, and make sure the back of the device
is in contact with your skin.
Fasten the band
1. Place Sense around your wrist. 2. Slide the bottom band through the first
loop in the top band.
13
3. Tighten the band until it fits comfortably, and press the peg through one
of the holes in the band.
4. Slide the loose end of the band through the second loop until it lies flat
on your wrist. Make sure the band isn’t too tight. Wear the band loosely
enough that it can move back and forth on your wrist.
Handedness
For greater accuracy, you must specify whether you wear Sense on your dominant
or non-dominant hand. Your dominant hand is the one you use for writing and
eating. To start, the Wrist setting is set to non-dominant. If you wear Sense
on your dominant hand, change the Wrist setting in the Fitbit app:
From the Today tab
Wrist
Dominant.
in the Fitbit app, tap your profile picture
Sense tile
14
Wear and care tips
l Clean your band and wrist regularly with a soap-free cleanser. l If your
watch gets wet, remove and dry it completely after your activity. l Take your
watch off from time to time. l If you notice skin irritation, remove your
watch and contact customer support.
For more information, see fitbit.com/productcare.
Change the band
Sense comes with a small band attached and an additional large, bottom band in
the box. Both the top and bottom bands can be swapped with accessory bands,
sold separately on fitbit.com. For band measurements, see “Band size” on page
76. Fitbit Versa 3 bands are compatible with Sense.
Remove a band
1. Turn over Sense and find the band latches.
2. To release the latch, slide the flat button toward the band.
15
3. Gently pull the band away from the watch to release it.
4. Repeat on the other side.
Attach a band
To attach a band, press it into the end of the watch until you hear a click
and it snaps into place. The band with the loops and peg attaches to the top
of the watch.

If Sense isn’t working properly, see our troubleshooting steps below.
Heart-rate signal missing
Sense continuously tracks your heart rate while you’re exercising and
throughout the day. If the heart-rate sensor on your watch has difficulty
detecting a signal, dashed lines appear.
If your watch doesn’t detect a heart-rate signal, make sure you’re wearing
your watch correctly, either by moving it higher or lower on your wrist or by
tightening or loosening the band. Sense 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. For more information, see the related help article.
GPS signal missing
Environmental factors including tall buildings, dense forest, steep hills, and
thick cloud cover can interfere with your watch’s ability to connect to GPS
satellites. If your watch is searching for a GPS signal during an exercise,
you’ll see ” connecting ” appear at the top of the screen. If Sense can’t
connect to a GPS satellite, the watch stops trying to connect until the next
time you start a GPS exercise.
72
For best results, wait for Sense to find the signal before you start your
workout.
If Sense loses the GPS signal during your workout, “GPS lost signal” appears
at the top of the screen. Your watch will attempt to reconnect.
For more information, see the related help article.
Can’t connect to Wi-Fi
If Sense can’t connect to Wi-Fi, you might have entered an incorrect password,
or the password might have changed:
1. From the Today tab
in the Fitbit app, tap your profile picture Sense
tile.
2. Tap Wi-Fi Settings Next.
3. Tap the network you want to use Remove.
4. Tap Add Network and follow the on-screen instructions to reconnect the Wi-
Fi network.
73
To check if your Wi-Fi network is working correctly, connect another device to
your network; if it connects successfully, try again to connect your watch.
If Sense still won’t connect to Wi-Fi, make sure that you’re attempting to
connect your watch to a compatible network. For best results, use your home
Wi-Fi network. Sense can’t connect to 5GHz Wi-Fi, WPA enterprise, or public
networks that require logins, subscriptions, or profiles. For a list of
compatible network types, see “Connect to Wi-Fi” on page 10.
After you verify the network is compatible, restart your watch and try
connecting to Wi-Fi again. If you see other networks appear in the list of
available networks, but not your preferred network, move your watch closer to
your router.
For more information, see the related help article.
Phone disconnected
When your Fitbit device isn’t connected to your phone, the phone disconnected
icon
appears for 3 seconds at the top of your clock face when you turn on the
screen. You might have trouble syncing and receiving notifications from your
phone. If your phone is nearby, follow the troubleshooting steps in the related help
article.
Other issues
If you experience any of the following issues, restart your watch:
l Won’t sync l Won’t respond to taps, swipes, or button press l Won’t track
steps or other data l Won’t show notifications
For instructions, see “Restart Sense” on page 70.

someone with nickel sensitivity, the amount of nickel in all Fitbit products
meets the European Union’s stringent Nickel Directive.
Our products may contain trace amounts of acrylates and methacrylates from
adhesives used in those products but we work to ensure our products adhere to
rigorous design specifications and meet extensive test requirements so as to
minimum the potential for reaction to these adhesives.
