Overview: The Garmin vívosmart 4 is a water-resistant smart activity
tracker with a built-in heart rate monitor that helps you reach your personalized daily
fitness goals. The slender, lightweight
device is worn on the wrist, and has a 0.26" x 0.7"
(48 x 128 pixels) touchscreen display. On the display, you can view your steps, calories burned, distances traveled,
heart rate, floors climbed, reps completed, and activity intensity. vívosmart 4
also alerts you when it's time to move, or when you receive an email, text, a
call on your smartphone, or a social media alert. It can even monitor your
sleep. This vívosmart 4 weighs just
0.58 ounces, and
has an adjustable wrist band that fits small-to-medium wrist circumferences of between
4.8" to 7.4".
A large-sized version
(in black only) is also available
for those with a wrist circumference of 5.8" to 8.5".
Elevate: The vívosmart 4 is equipped with Elevate
wrist-based heart rate technology. A Pulse Ox sensor, located on the bottom of the
activity tracker, continuously measures your heart rate and blood oxygen
saturation levels at the wrist. There
is no need to wear a separate heart rate strap. The vívosmart 4 can broadcast
your heart rate (in beats per minute) to other compatible Garmin
devices, such an Edge cycling device or VIRB action camera.
Body Battery: The device can gauge your body's energy
reserves at any moment. Your Body Battery reading is calculated using a
combination of stress, heart rate variability, sleep, and activity data. Knowing
your energy reserve level helps you to know when it's best to be active, and
when you should rest. The Body Energy reading is expressed numerically between 0
and 100, with a trending arrow indicating if your energy reserve is increasing,
decreasing, or holding steady.
Garmin Connect: The vívosmart 4 has built-in Bluetooth Smart
technology so you can automatically pair it to your smartphone or mobile device.
With the Garmin Connect app on your smartphone or computer, you can keep track
of your activities, your daily goals, the calories you've burned, and help
motivate you to keep active. You can also share your activities and goals with
your friends on social media. The vívosmart 4 settings are configured on Garmin
Connect, including Time Format (12-hour or 24-hour), Measurement Units (miles or
kilometers), Visible Screens, and Auto Goal. Garmin Connect for your home
computer is compatible with Windows 7 SP1 and newer and Mac OS X v10.11 or
later. Garmin Connect Mobile works with Bluetooth 4.0-enabled devices running
Android 4.0 or higher, or iOS 9.0 and above.
Widgets: The Garmin vívosmart 4's on-screen widgets provide
feedback on many activities. You can keep track of your activity
level throughout the day and view the results on the screen at any time. Additional sensors, such as a bike speed sensor, can be paired to the device. You can swipe the touchscreen
display left or right to scroll through the widgets. Some of the
activities and display screens include:
- Time/Date: Displays the current time, day, and date
(can be set manually, or automatically when it syncs up to your mobile
- Steps: Provides a count of the steps you take, and you
daily step goal. As you progress, the device will propose a new step goal
- Floors: Similar to the Steps widget, the device keeps
track of the number of floors climbed and your goal for the day.
- Intensity Minutes: The vívosmart 4 counts the number of
minutes spent in vigorous activity, plus your goal for the week.
- Calories Burned: Keeps track of the number of total
calories burned for the day, including active and resting calories.
- Distance: Keeps track of the total distance traveled
for the day, expressed in miles or kilometers.
- VIRB: Remote controls for a paired VIRB action camera.
- Heart Rate: Shows your current heart rate and 7-day
average resting heart rate in beats per minute (BPM).
- Music Controls: Music controls for the music player on
a paired mobile
- Temperature/Weather: Displays the current temperature
and weather forecast. Requires connection to a smartphone.
- Notifications: You receive notification of new texts, emails, social
network updates, and phone calls received from the paired mobile device. The
notifications include visual alerts, as well as vibrations.
- Message: A custom message that you create on the Garmin
Connect Mobile app appears in the display.
- Stress Level: Displays your current stress level, based
on your heart rate variability while you are inactive. The lower the number,
the lower your stress level.
- Body Battery: Displays your current Body Battery energy
reserve, based on sleep, stress, and activity data. The higher number
indicates a higher energy reserve.
Advanced Sleep Monitoring: The vívosmart 4 can help you
analyze your sleep, by monitoring your movement, heart rate, and blood oxygen
levels. The device tracks your light, deep, and REM stages of sleep, and allows
you to view your sleep stats in the Garmin Connect mobile app.
Note: Pulse Ox monitoring during sleep can greatly reduce the
Stress Tracking: The device can analyze your heart rate
variability while you are inactive to determine your overall stress. Your stress
level is expressed within a range of 0 to 100: 0-25 resting state, 26-50 low
stress, 51-75 medium stress, and 76-100 high stress. When stress levels are
high, you can use the relaxation-based breathing timer (a 1 to 5 minute
breathing exercise) on the stress widget to help lower your stress level.
Syncing your device to your Garmin Connect account lets you see your stress
level throughout the day, stress trends, and which parts of the day are the most
stressful. For best results, you should wear the device while sleeping.
Move IQ: The vívosmart 4's Move IQ feature automatically
detects activity patterns, such as biking, swimming, walking, or running, for at
least 10 minutes. This eliminates the need to start or stop the activity timer
each time you begin a new activity. You can view the event type and duration on
the Garmin Connect timeline, but they do not appear in your activities list,
snapshots, or newsfeed.
History: The device can store up to 14 days of activity data
(daily steps, calories burned, sleep statistics), heart rate monitoring data,
and up to 7 timed activities. Data storage capability depends
upon how often you upload the data to your computer.
Water Resistance: The vívosmart 4 is designed with a high
water resistance rating, allowing you to wear the device in the rain and wet
weather, as well as in the shower or while swimming.
Battery: The vívosmart 4 is powered by a built-in rechargeable
Lithium-Polymer battery with a battery life of up to 7 days, excluding pulse ox
sleep tracking. A 22" charging/data
cable is included with the device.
