Vivofit 4: Sleep Tracking And More

The Garmin Vivofit 4 is a daily activity tracker with an incredible 1+ year battery life and no charging required. It is an affordable Fitbit rival with unbeatable battery life, although it lacks heart rate tracking. The Vivofit 4 also includes sleep monitoring, but how accurate is it?

The Garmin Vivofit 4 tracks sleep but not very well

The Garmin Vivofit 4 is a daily activity tracker with an incredible 1+ year battery life and no charging necessary. It has a built-in always-on display that is easy to read in bright sunlight and in the dark, making it comfortable enough for sleeping. The device also includes a weather widget and a "Find My Phone" feature.

The Vivofit 4 has its strengths, but one of its weaknesses is sleep tracking. While it does track sleep, it doesn't do so very accurately. This may be because Garmin's Move IQ technology requires movement to work. For example, the Vivofit 4 will think you're asleep if you're sitting on the couch playing video games, lying in bed reading, or even typing furiously at 2 a.m. while maintaining excellent posture and a neutral wrist position.

The device automatically detects your sleep and monitors your movement during your normal sleep hours, which can be set in the user settings on your Garmin Connect account. Sleep statistics include total hours of sleep, sleep levels, and sleep movement, but naps are not added to these statistics. The Vivofit 4 only tracks one sleep period per day, and it does so during a pre-defined timeslot. This means that if you take a nap or go to bed outside of your set sleep hours, it will not be tracked.

Compared to other devices, such as Fitbit and Samsung, the Vivofit 4's sleep tracking capabilities are lacking. These alternative devices can track multiple sleep periods per day and do not rely solely on movement to detect sleep. While the Vivofit 4 has its strengths, such as its long battery life and activity-tracking technology, sleep tracking is not its forte.

The device monitors sleep movement and total sleep

The Garmin Vivofit 4 is a fitness tracker with a battery life of over a year, which means it never needs to be charged. The device can monitor sleep movement and total sleep. While you are sleeping, the device automatically detects your sleep and monitors your movement during your normal sleep hours. You can set your normal sleep hours in the user settings on your Garmin Connect account. Sleep statistics include total hours of sleep, sleep levels, and sleep movement. You can view your sleep statistics on your Garmin Connect account.

The Vivofit 4 is also packed with solid activity-tracking technology. It works with the Garmin Connect app, which is compatible with Garmin and ANT+ devices. The device can be used as an everyday watch, complete with a countdown timer, stopwatch, and multiple alarms. It can also be customized with various watch faces, color themes, and personalized text.

However, the Vivofit 4's sleep tracking feature has received mixed reviews. Some users have reported that the device accurately tracks their sleep, while others have found it to be inaccurate. For example, some people have noticed that the device will think they are asleep if they are sitting still and playing video games or reading in bed. Additionally, the device only tracks one sleep period per day, which may be a disadvantage for people who take naps during the day.

Despite these limitations, the Vivofit 4 can be a useful tool for monitoring sleep and improving sleep habits. It is important to remember that no device is perfect out of the box, and it may take time for the Vivofit 4 to learn your unique sleep patterns and movements.

It is not as accurate as the Fitbit Inspire HR

The Garmin Vivofit 4 does track sleep, but it is not as accurate as the Fitbit Inspire HR. While the Vivofit 4 has its advantages, such as its unbeatable battery life and compatibility with the Garmin Connect app, its sleep-tracking capabilities are limited. For example, it may incorrectly assume you are asleep if you are sitting still or lying down, even if you are playing video games or reading.

On the other hand, the Fitbit Inspire HR offers more accurate sleep tracking. The Fitbit Inspire series, including the Inspire 2 and Inspire 3, are all capable of tracking sleep. While studies comparing the accuracy of Fitbit devices to polysomnography (PSG) are limited, one study found that the Fitbit Inspire 2 had a sensitivity of 93.9%, specificity of 13.1%, and accuracy of 76.0% in terms of total sleep results. Another study reported that the Fitbit Inspire 2 had high accuracy in participants with sleep disturbances.

The Fitbit Inspire HR also provides heart rate tracking, which is a feature that the Vivofit 4 lacks. This may be a significant consideration for casual users seeking an entry-level fitness tracker that offers a comprehensive overview of their health and activity. The Vivofit 4's lack of heart rate tracking may be a drawback for those who want a device that can monitor their sleep and heart rate in addition to their daily activities.

While the Vivofit 4 has a better design and more aesthetic upgrades compared to its previous generations, its sleep tracking capabilities are not as advanced as those of the Fitbit Inspire HR. The Fitbit Inspire series provides a good balance of features, including sleep tracking, heart rate monitoring, and activity tracking, making them popular choices for those seeking an affordable and reliable fitness tracker.
