The Garmin Vivosmart 4 Activity Tracker


Founded in 1989, Garmin is a brand that many customers associate with GPS tracking for vehicles. However, the company soon realized that their vehicle tracking technology could be brilliantly repurposed and aimed towards their more health-conscious customers.

Their vivosmart 4 is both stylish and practical. It’s slim and comfortable with a bright, easy-to-read screen.

The vivosmart 4 tracks your sleep in the light, deep, and REM stages as well as letting you know how much you moved during the night. Additionally, the vivosmart 4 uses preloaded activity timers, Elevate heart rate data, and a Pulse Ox feature that monitors your blood’s oxygen absorption rate. What makes the vivosmart stand apart as a tracker is that it also keeps tabs on your stress levels. It’s one of the rare health trackers that actively encourages you to take a moment for yourself to breathe easy and to prioritize your mental and emotional state.

This vivosmart sleep and fitness monitor uses a variety of sensors and app features to offer a complete picture of how healthy you are. It gives you the opportunity to set a series of goals when it comes to sleep, managing stress, and exercise.

The vivosmart comes in four colors: gray, azure blue, berry, and black.

Sleep Tracking

What makes the vivosmart 4 such an effective sleep tracking device comes down to a few key components. Firstly, the vivosmart is a very slim, lightweight tracker that fits comfortably around the wrist. It’s easy to wear to bed because it won’t interfere with your ability to naturally drift off to sleep.

Once you’re ready for bed, the vivosmart uses its Elevate feature to detect changes to your heart rate, using your slowing heart rate as a vital clue that you’ve gone to sleep. At this point, the vivosmart 4 begins to track you through light, deep, and REM stages of sleep. It uses the Pulse OX sensor which, based on data about your current overall fitness, estimates how well your blood absorbs oxygen while you sleep. The vivosmart also makes note of how often you move during the night and if you experience any sleep disturbances.

When you wake up, you can view all the information recorded during the night on the Garmin Connect Mobile App. When you do lay down to rest, you’ll want to make sure you wear the tracker tight enough across your skin for sensors to effectively record data. Should you decide to take a nap during the day, you can do so without worrying about it skewing sleep tracking accuracy; the vivosmart doesn’t count daytime naps towards your overall sleep data.

Additional Features

In addition to providing accurate sleep tracking data, the vivosmart 4 provides a variety of features meant to help you be more active and healthy in your waking life. For instance, the smart device provides personalized step goals every day. Keep track of your fitness by using preloaded activity timers. Thanks to the Move IQ feature, vivosmart 4 automatically detects certain activities such as cycling, walking, or swimming.

One of the best aspects of vivosmart is that in addition to fitness and sleep, it keeps tabs on your stress levels. It does this by monitoring your heart rate variability (HRV), or the time between each heartbeat. By turning on the Relax Reminder, vivosmart will vibrate an alert if you seem particularly stressed. During such moments, the device will walk you through breathing techniques meant to help lower your heart rate and make you feel more relaxed.

When not keeping tabs on your health, you can also use the vivosmart 4 sleep and fitness tracker to check the weather, control music, or receive certain smart notifications.


Because vivosmart 4 is a very accurate sleep tracker loaded with a wide range of fitness-related features, it’s no surprise that the device comes with a premium price tag. It does possess a wide range of capabilities similar to smartwatches and trackers within the same price range. Therefore, it’s priced in a way that makes sense for the features provided.

Battery Life

The vivosmart 4 sleep and fitness tracker enjoys a battery life of up to one week. That’s without the Pulse OX sleep tracking feature, which could shorten battery life depending on the amount of use.

Should your battery run out of energy, connect it to the accompanying charge cable, which plugs into an available USB port. It should take about two hours to fully charge.


The accompanying Garmin Connect app is compatible with iPhone, iPad, and iPod touch devices running iOS 10.0 or later. Android devices should have 4.4 OS or later and Bluetooth 4.0 or higher. Garmin actively makes the effort to ensure its smart trackers are compatible with as many smartphones as possible.
