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 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 see your health metrics, activity and sleep
data, choose a workout or mindfulness session, 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.

For more information, see the related help article.
11
Wear Sense
WearSense 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 page15.
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 in the Fitbit app, tap your profile picture Sense tile
Wrist Dominant.
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.
For more information, visit the Fitbit Wear & Care page.
Change the band
Sense comes with a small band attached and an additional large, bottom band in
the box. Boththe top and bottom bands can be swapped with accessory bands,
sold separately on fitbit.com. For band measurements, see "Band size" on page75.
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.

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 GPSsatellite, the watch
stops trying to connect until the next time you start a GPSexercise.
71
For best results, wait for Sense to find the signal before you start your workout.
If Sense loses the GPSsignal during your workout, "GPSlost 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.
72
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, WPAenterprise, or public networks that require
logins, subscriptions, or profiles. For a list of compatible network types, see
"Connect to Wi-Fi" on page10.
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 page69.

Materials
The band that comes with Sense is made of a flexible, durable elastomer material
similar to that used in many sports watches.
The housing and buckle on Sense are made of anodized aluminum. While anodized
aluminum can contain traces of nickel, which can cause an allergic reaction in
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.
